Shenzhen MYGT Co., Ltd Date: 2026/9/20 Federal Communications Commission Authorization and Evaluation Division 7435 Oakland Mills Road Columbia, MD 21046 USA Subject: Label Justification Letter for FCC ID: [2AMKE-BS-T20] Product: [Black Shark Open Ear Pro] / [BS-T20] Dear Sir or Madam, We request approval to place the FCC ID in the user manual and on the packaging (or a removable label) instead of on the device itself. Justification: The device is too small to label with a font size of four-points or larger, and it does not use electronic labeling. Alternative Labeling: Per 47 CFR §15.19(a)(5), the FCC ID will be placed in the user manual and on the device packaging (or a removable label attached to the device). See the " T20-Color box and manual" exhibit for details. Sincerely, Shenzhen MYGT Co., Ltd [Name] Xianming Xu [Title] Program Manager [Company Name] Shenzhen MYGT Co., Ltd [Email] [email protected]

RF Exposure Info

FCC ID: 2AMKE-BS-T20 Portable device According to §15.247(e)(i) and §1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. According to KDB447498 D01 General RF Exposure Guidance V06 The 1-g SAR and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)]·[√f(GHZ)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where: • f(GHZ) is the RF channel transmit frequency in GHz • Power and distance are rounded to the nearest mW and mm before calculation • The result is rounded to one decimal place for comparison When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion.
