DESIGN ASSURANCE ENGINEERING Wireless Transceiver DSS/DTS Test Report Certificate # 1514.1 FCC ID: A94429638 IC: 3232A-429638 Test Report Summary Product Information: Description The EUT is a wireless headphone that contains DSS/DTS transceivers, manufactured by Cambridge Silicon Radio, CSR8675. The EUT uses Adaptive Frequency Hopping (AFH) mode, using a reduced hop set if interference is detected in band, however a minimum of 20 channels is always maintained. The two models use identical electronics and are differentiated only by cosmetic differences in the enclosure. The differences in the enclosures have no impact on the transmitter function or characteristics. Model BMD003 was used for testing. Setup (Cables and Accessories) Spurious emissions was performed with the EUT playing IEC pink noise over the wireless link, with the EUT sensors operating and sending data over the wireless link, or while the EUT battery is charging from an external power supply. The EUT cannot charge and play audio at the same time. EUT is not sold with a power supply so when necessary a Bose model number S008AHU0500160 power supply was used for charging. For radio tests the radio was configured with CSR Blue Suite software (details provided in SOFTWARE AND FIRMWARE section). EUT Antenna Description The antenna is an internal PIF variant with antenna gain of 5.65 dBi formed by printed circuit board etch. SOFTWARE AND FIRMWARE The firmware installed in the EUT during testing was version 0.6.3 The test utility software used during testing was Polycomm, version 0.2.1.0 and CSR Blue Suite version 2.6.2. Scope: This report covers EMC requirements. FCC CFR 47 PART 15 SUBPART C, Industry Canada RSS-247 Issue 2, and Industry Canada RSS-GEN Issue 5. All measurements in this report were made radiated, with the EUT antenna connected. Test Objective: Verify product meets all applicable EMC requirements. Measurement Method: ANSI C63.10 (2013). Results: Product complies with all applicable EMC requirements. All final results represent worst-case emissions and/or immunity. Conclusions: The device under test (D.U.T.): [X] meets all test standards selected in section 2 of this report. [ ] does not meet all test standards selected in section 2 of this report.

DESIGN ASSURANCE ENGINEERING Wireless Transceiver DSS/DTS Test Report Certificate # 1514.1 FCC ID: A94429638 IC: 3232A-429638 Radiated Emissions 30 MHz to 1 GHz Requirement: Spurious emissions shall not exceed the radiated emissions limits shown below radiated emissions limits Test Procedure: The EUT is placed on a non-conducting table 80 cm above the ground plane for below 1GHz measurements. The EUT is rotated around the vertical axis, the antenna polarization changed from H to V and the antenna height is varied from 1 to 4 meters in order to find the maximum value of the harmonic emission. Account is taken of the beam width of the antenna to make sure the EUT remains in the main lobe of the antenna. EUT was tested in 3 orthogonal axes and the worst-case results are shown below. For measurements below 1 GHz, the resolution bandwidth is set to 120 kHz and a quasi-peak detector was used. Test setup details: EUT is playing pink noise at max volume via Bluetooth from an ipod; sensors are not active (sensors have no impact on radiated emissions performance). EUT is powered by the internal battery. Worst case orientation found to be with the glasses closed and the lenses down. EUT is connected to a power supply and charging; no audio is playing, no sensors are active. EUT is not provided with a power supply; using Bose power supply MN: S008AHU0500160. Worst case orientation found to be with the glasses open and the lenses forward.

DESIGN ASSURANCE ENGINEERING Wireless Transceiver DSS/DTS Test Report Certificate # 1514.1 FCC ID: A94429638 IC: 3232A-429638 Radiated Emissions 1 GHz to 40 GHz Requirement: FCC 15.205, 15.209, 15.247 (d), IC RSS-GEN Clause 8.9 (Transmitter) Restricted Bands: In any of the restricted bands defined in FCC part 15.209(a), the field strength at a distance of 3 meters shall not exceed 54dBμV/m (average) or 74dBμV/m (peak) Non-Restricted Bands: In any 100 kHz bandwidth outside the frequency band in which the spread spectrum or digitally modulated device is operating, the RF power that is produced shall be at least 20 dB below that in the 100 kHz bandwidth within the band that contains the highest level of the desired power, based on either an RF conducted or a radiated measurement, provided that the transmitter demonstrates compliance with the peak conducted power limits. If the transmitter complies with the conducted power limits based on the use of root-mean-square averaging over a time interval, the attenuation required shall be 30 dB instead of 20 dB. Attenuation below the general field strength limits specified in RSS-Gen is not required. Test Procedure: The EUT is placed in a standard ANSI C63.10 test setup. Standard Gain Horn Antennas and Double-Ridged Guide Horn Antennas with suitable pre-amps mounted directly on the horn antennas are used for the measurement of the harmonics. The EUT hopping is stopped and measurements are made in the low, mid and high end of the frequency range at the defined limit distance of 3 meters. The EUT is placed on a non-conducting table 80 cm above the ground plane for below 1GHz measurements and 1.5 m above the ground plane for above 1GHz measurements. The EUT is rotated around the vertical axis, the antenna polarization changed from H to V and the antenna height is varied from 1 to 4 meters in order to find the maximum value of the harmonic emission. Account is taken of the beam width of the horn antennas to make sure the EUT remains in the main lobe of the antenna. EUT was tested in 3 orthogonal axes and the worst-case results are shown below. For peak measurements above 1 GHz, a resolution bandwidth of 1 MHz was used and video bandwidth of 3 MHz was used. For average measurements above 1GHz, the resolution bandwidth and video bandwidth are set as described in ANSI C63.10:2013 for the applicable measurement. An average detector was used and a duty cycle correction factor was added to correspond to the average during the transmission to compute the emission level that would have been measured had the test been performed at 100 % duty cycle. The duty cycle correction factor used was 2.2 dB for DH5 Bluetooth and 3.6 dB for BLE. Test setup details: The EUT is software programmed via the USB cable with software which is used to set the test modes of the Bluetooth device. The EUT antenna is connected, the measurements are made using a radiated emissions setup. Testing performed in the worst case orientation - with the glasses closed and the lenses down. Spurious/Harmonics The EUT is transmitting at full power, either on 2402 MHz, 2441 MHz (BT) or 2442 MHz (BLE), 2480 MHz, or hopping on low/mid/high channels. For Bluetooth mode, DH5 packets were used. Band-edge The EUT is transmitting at full power, either on 2402 MHz, 2480 MHz, or hopping on all channels. For Bluetooth mode, DH5 and 3DH5 packets were used.
