This Amendment No. 4 to Schedule 13D (this Amendment No. 4) amends and supplements the Schedule 13D filed on July 6, 2018 (as amended on February 11, 2020, February 26, 2020 and August 31, 2020, the Schedule 13D) with the U.S. Securities and Exchange Commission (the SEC), relating to the shares of common stock, par value $0.01 per share (PLT Common Stock), of Plantronics, Inc. (the Issuer or the Company). Unless specifically amended hereby, the disclosures set forth in the Schedule 13D remain unchanged. Capitalized terms used in this Amendment No. 4 that are not otherwise defined herein have the meanings attributed to them in the Schedule 13D.

Item 4. Purpose of Transaction

Item 4 of the Schedule 13D is hereby amended and supplemented by adding the following:

On November 23, 2020, Triangle Holdings II sold 1,011,350 shares of PLT Common Stock at a price per share of $24.00 in a block sale to a broker-dealer.

Item 5. Interest in Securities of the Issuer

Item 5 (a) - (c) and (e) of the Schedule 13D is hereby amended and restated in its entirety as follows:

(a) and (b)

None of the Reporting Persons has the sole power to vote or direct the vote or the sole power to dispose or direct the disposition of any of the shares of PLT Common Stock to which this Schedule 13D relates. All of the Reporting Persons have shared power to vote or direct the vote and shared power to dispose or direct the disposition of 1,973,884 shares of PLT Common Stock reported in this Schedule 13D, which constitute approximately 4.8% of the outstanding shares of PLT Common Stock. In addition, Siris Capital Group and Siris Group GP also have shared power to vote or direct the vote and shared power to dispose or direct the disposition of 8,303 shares of PLT Common Stock (which shares were awarded to Frank Baker in connection with his service as a former director of the Issuer) reported in this Schedule 13D, which constitute approximately 0.02% of the outstanding shares of PLT Common Stock and, when aggregated with the shares of PLT Common Stock referenced in the previous sentence, constitutes approximately 4.8% of the outstanding shares of PLT Common Stock. Pursuant to an assignment agreement between Siris Capital Group and Mr. Baker, Mr. Baker has assigned to Siris Capital Group all of his right, title and interest in and to any compensation, including equity awards, he receives from the Issuer for his services as a director of the Issuer.

The percentages set forth above are based on an aggregate of 41,246,609 shares of PLT Common Stock outstanding as of October 26, 2020, as reported in the Companys Quarterly Report on Form 10-Q, filed with the SEC on October 30, 2020.

The Reporting Persons may be deemed to be members of a group for purposes of Section 13(d) of the Act, which group may be deemed to share the power to vote or direct the vote, or to dispose or direct the disposition, of the PLT Shares. However, neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission by any of the Reporting Persons that it is a member of a group for purposes of Section 13(d) of the Act or for any other purpose. Each of the Reporting Persons expressly disclaims beneficial ownership of securities held by any other person or entity other than, to the extent of any pecuniary interest therein, the various accounts under such Reporting Persons management and control.

(c)

The Reporting Persons engaged in the following transaction with respect to the PLT Common Stock during the last sixty days: on November 23, 2020, Triangle Holdings II sold 1,011,350 shares of PLT Common Stock at a price per share of $24.00 in a block sale to a broker-dealer.

(e)

The Reporting Persons ceased to be the beneficial owners of more than five percent of the outstanding shares of PLT Common Stock on November 23, 2020.
