<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:8%; font-size:10pt; font-family:Times New Roman">On July&nbsp;1, 2015, Orange Subsidiary, Inc., a wholly-owned subsidiary of the Registrant (&#147;Merger Sub&#148;), merged (the
&#147;Merger&#148;) with and into Audience, Inc. (&#147;Audience&#148;), with Audience continuing as the survivor of such merger and as a wholly owned subsidiary of the Registrant, pursuant to the terms and conditions of an Agreement and Plan of
Merger, dated as of April&nbsp;29, 2015, among the Registrant, Audience and Merger Sub (the &#147;Merger Agreement&#148;). Under the Merger Agreement, certain options to purchase Audience common stock granted under the Plan and all outstanding
Audience restricted stock units that were outstanding immediately prior to the effective time of the Merger (the &#147;Effective Time&#148;) were assumed by the Registrant and converted into an option to purchase Common Stock or restricted stock
units of Knowles, as the case may be, on the same terms and conditions as the Audience stock options and restricted stock units, respectively (but taking into account any changes thereto, including any acceleration, lapse or other vesting, provided
in the Plan or related award documents by reason of the Merger). The number of shares of Common Stock subject to each such converted stock option and restricted stock unit equals the number of shares of Audience common stock subject to such Audience
stock option or restricted stock unit, respectively, multiplied by the conversion ratio, rounded down to the nearest whole share of Common Stock. The conversion ratio equals 0.2647 which equals the fraction (rounded to the nearest 1/10,000) having a
numerator equal to $5.01, and having a denominator equal to the volume weighted average of the sale prices for Common Stock as reported on the New York Stock Exchange for each of the 10 consecutive trading days ending on and including the second
trading day prior to the final expiration date of the tender offer made by Merger Sub for outstanding shares of Audience common stock (without any adjustment thereto pursuant to application of the collar). Also at the Effective Time, the Registrant
assumed the Plan, as amended and adjusted. This Registration Statement relates to shares that may be issued for future awards granted by the Registrant under the Plan and to the outstanding Audience options and restricted stock units assumed by
Registrant in connection with the Merger. </P> <P STYLE="margin-top:24pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman" ALIGN="center"><B>PART I </B></P>

settlement in connection with any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, in which such person is made a party by reason of the fact that the person is or was a director,

except that indemnification only extends to expenses (including attorneys&#146; fees) incurred in connection with the defense or settlement of such action, and the statute requires court approval before there can be any indemnification where the
person seeking indemnification has been found liable to the corporation. The statute provides that it is not exclusive of other indemnification that may be granted by a corporation&#146;s bylaws, disinterested director vote, stockholder vote,

proceeding if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Registrant, and, with respect to any criminal action or proceeding, had no reasonable cause to believe
such person&#146;s conduct was unlawful. The By-Laws also provide that the Registrant shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of
the Registrant to procure a judgment in its favor by reason of the fact that such person is or was a director or officer of the Registrant, or is or was a director, officer or employee of the Registrant serving at the request of the Registrant as a

Registrant in advance of the final disposition of such action, suit or proceeding. The indemnification and advancement of expenses provided by, or granted pursuant to, the By-Laws are not exclusive of any other rights to which those seeking
indemnification or advancement of expenses may be entitled under the Certificate of Incorporation, the By-Laws, any statute, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in such person&#146;s official
capacity and as to action in another capacity while holding such office. Any repeal or modification of the indemnification or advancement of expenses provisions of the By-Laws will not adversely affect any right or protection thereunder of a
director, officer or employee of the Registrant in respect of any proceeding (regardless of when such proceeding is first threatened, commenced or completed) arising out of, or related to, any act or omission occurring prior to the time of such
repeal or modification. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Registrant maintains liability insurance for its directors and officers. Such insurance is available to the

Represents 463,419 common shares of Knowles Corporation (the "Registrant"), $0.01 par value per share ("Common Stock"), originally registered on the Registration Statement on Form S-4 (Registration
No. 333-204291), which are issuable pursuant to outstanding stock options and restricted stock units of Audience, Inc., and 176,438 shares of Common Stock reserved for issuance under the Audience, Inc. Amended and Restated 2011 Employee Stock
Purchase Plan, as amended or supplemented from time to time (the "Plan") as adjusted and assumed by the Registrant on July 1, 2015 pursuant to the terms of that certain Agreement and Plan of Merger, dated as of April 29, 2015,
among the Registrant, Audience, Inc. and Orange Subsidiary, Inc. This Registration Statement also covers such additional and indeterminate number of shares of Common Stock as may become issuable under the Plan by reason of any stock dividend, stock
split, recapitalization or other similar transaction effected without the Registrant's receipt of consideration, which results in an increase in the number of the outstanding shares of Common Stock.

Estimated in accordance with Rules 457(c) and (h) under the Securities Act, solely for the purpose of calculating the registration fee. The price of $18.72 per share represents the average of the high and low sales
prices of the Registrant's common shares as reported on the New York Stock Exchange on July 13, 2015.

The registration fees are being offset in respect of registration fees in respect of 463,419 shares of Common Stock equal to $1,008.06, that were paid in connection with the original filing on May 19, 2015 of the
Registrant's Registration Statement on Form S-4 (Registration No. 333-204291). Such Registration Statement was declared effective on June 30, 2015.
EXPLANATORY NOTE
On July 1, 2015, Orange Subsidiary, Inc., a wholly-owned subsidiary of the Registrant ("Merger Sub"), merged (the
"Merger") with and into Audience, Inc. ("Audience"), with Audience continuing as the survivor of such merger and as a wholly owned subsidiary of the Registrant, pursuant to the terms and conditions of an Agreement and Plan of
Merger, dated as of April 29, 2015, among the Registrant, Audience and Merger Sub (the "Merger Agreement"). Under the Merger Agreement, certain options to purchase Audience common stock granted under the Plan and all outstanding
Audience restricted stock units that were outstanding immediately prior to the effective time of the Merger (the "Effective Time") were assumed by the Registrant and converted into an option to purchase Common Stock or restricted stock
units of Knowles, as the case may be, on the same terms and conditions as the Audience stock options and restricted stock units, respectively (but taking into account any changes thereto, including any acceleration, lapse or other vesting, provided
in the Plan or related award documents by reason of the Merger). The number of shares of Common Stock subject to each such converted stock option and restricted stock unit equals the number of shares of Audience common stock subject to such Audience
stock option or restricted stock unit, respectively, multiplied by the conversion ratio, rounded down to the nearest whole share of Common Stock. The conversion ratio equals 0.2647 which equals the fraction (rounded to the nearest 1/10,000) having a
numerator equal to $5.01, and having a denominator equal to the volume weighted average of the sale prices for Common Stock as reported on the New York Stock Exchange for each of the 10 consecutive trading days ending on and including the second
trading day prior to the final expiration date of the tender offer made by Merger Sub for outstanding shares of Audience common stock (without any adjustment thereto pursuant to application of the collar). Also at the Effective Time, the Registrant
assumed the Plan, as amended and adjusted. This Registration Statement relates to shares that may be issued for future awards granted by the Registrant under the Plan and to the outstanding Audience options and restricted stock units assumed by
Registrant in connection with the Merger.

Item 6.
Indemnification of Directors and Officers.
Section 145 of the Delaware General
Corporation Law ("DGCL") provides that a corporation may indemnify directors and officers as well as other employees and agents of the corporation against expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement in connection with any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, in which such person is made a party by reason of the fact that the person is or was a director,
officer, employee or agent of the corporation (other than an action by or in the right of the corporation—a "derivative action"), if such person acted in good faith and in a manner such person reasonably believed to be in or not
opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe such person's conduct was unlawful. A similar standard is applicable in the case of derivative actions,
except that indemnification only extends to expenses (including attorneys' fees) incurred in connection with the defense or settlement of such action, and the statute requires court approval before there can be any indemnification where the
person seeking indemnification has been found liable to the corporation. The statute provides that it is not exclusive of other indemnification that may be granted by a corporation's bylaws, disinterested director vote, stockholder vote,
agreement or otherwise.
The Registrant's amended and restated certificate of incorporation (the "Certificate of
Incorporation") provides that no director shall be liable to the Registrant or the Registrant's shareholders for monetary damages for breach of fiduciary duty as a director, except to the extent such exemption from liability or limitation
thereof is not permitted under the DGCL, as now in effect or as amended. Currently, Section 102(b)(7) of the DGCL requires that liability be imposed for the following:
•
any breach of the director's duty of loyalty to the Registrant or its shareholders;
•
any act or omission not in good faith or which involved intentional misconduct or a knowing violation of law;
•
unlawful payments of dividends or unlawful stock purchases or redemptions as provided in Section 174 of the DGCL; and
•
any transaction from which the director derived an improper personal benefit.
The Certificate
of Incorporation also provides that the Registrant shall indemnify its directors and officers to the fullest extent authorized or permitted by law. A director's or officer's right to indemnification under the Certificate of Incorporation
includes the right to be paid by the Registrant the expenses incurred in defending or otherwise participating in any proceeding in advance of its final disposition. The rights to indemnification and advancement of expenses in the Certificate of
Incorporation are not exclusive of any other right which any person may have under the Certificate of Incorporation, amended and restated by-laws (the "By-Laws"), any statute, agreement, vote of shareholders or disinterested directors or
otherwise. In addition, any repeal or modification of the indemnification or advancement of expenses provisions in the Certificate of Incorporation will not adversely affect any rights to indemnification and to the advancement of expenses of a
director or officer of the Registrant existing at the time of such repeal or modification with respect to any acts or omissions occurring prior to such repeal or modification.
The Registrant's By-Laws provide that the Registrant shall indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the Registrant), by reason of the fact that such person is or was a director or
officer of the Registrant, or is or was a director, officer or employee of the Registrant serving at the request of the Registrant as a director, officer, employee or agent of, or in a fiduciary capacity with respect to, another corporation,
partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or
proceeding if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Registrant, and, with respect to any criminal action or proceeding, had no reasonable cause to believe
such person's conduct was unlawful. The By-Laws also provide that the Registrant shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of
the Registrant to procure a judgment in its favor by reason of the fact that such person is or was a director or officer of the Registrant, or is or was a director, officer or employee of the Registrant serving at the request of the Registrant as a
director, officer, employee or agent of, or in a fiduciary capacity with respect to, another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees) actually and reasonably incurred by
such person in connection with the defense or settlement of such action or suit if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Registrant. Expenses (including
attorneys' fees) incurred by a current or former director or officer or employee entitled to indemnification under the By-Laws in defending any civil, criminal, administrative or investigative action, suit or proceeding will be paid by the
Registrant in advance of the final disposition of such action, suit or proceeding. The indemnification and advancement of expenses provided by, or granted pursuant to, the By-Laws are not exclusive of any other rights to which those seeking
indemnification or advancement of expenses may be entitled under the Certificate of Incorporation, the By-Laws, any statute, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in such person's official
capacity and as to action in another capacity while holding such office. Any repeal or modification of the indemnification or advancement of expenses provisions of the By-Laws will not adversely affect any right or protection thereunder of a
director, officer or employee of the Registrant in respect of any proceeding (regardless of when such proceeding is first threatened, commenced or completed) arising out of, or related to, any act or omission occurring prior to the time of such
repeal or modification.
The Registrant maintains liability insurance for its directors and officers. Such insurance is available to the
Registrant's directors and officers in accordance with its terms.

Undertakings.
(a) The undersigned registrant hereby undertakes:
(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:
(i)
To include any prospectus required by Section 10(a)(3) of the Securities Act;
(ii)
To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a
fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was
registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price
represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective Registration Statement; and
(iii)
To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement;
provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) of this section do not apply if the information required to be
included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Exchange Act that are incorporated by reference in the
Registration Statement.
(2) That, for the purpose of determining any liability under the Securities Act, each such
post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the
termination of the offering.
(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act,
each filing of the registrant's annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act)
that is incorporated by reference in this Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.
(c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to
directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the
registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
SIGNATURES
Pursuant to the requirements of the Securities Act of 1933, the registrant certifies that it has reasonable grounds to believe that it meets
all of the requirements for filing on Form S-8 and has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the Village of Itasca, State of Illinois, on this 15
th
day of July, 2015.
