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)
                  Power line conducted emissions was performed 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.

          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.


          Test Objective:

                     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.

Powerline Conducted Emissions
Requirement:
For radio apparatus that are designed to be connected to the public utility AC power network, the radio frequency voltage that is
conducted back onto the AC power line on any frequency or frequencies within the range 150 kHz to 30 MHz shall not exceed
the limits below, as measured using a 50 μH / 50 Ω line impedance stabilization network. This requirement applies for the radio
frequency voltage measured between each power line and the ground terminal of each AC power-line mains cable of the EUT.

For an EUT that connects to the AC power lines indirectly, through another device, the requirement for compliance with the limits
in table 4 shall apply at the terminals of the AC power-line mains cable of a representative support device, while it provides
power to the EUT. The lower limit applies at the boundary between the frequency ranges. The device used to power the EUT
shall be representative of typical applications.

                                    Note 1: The level decreases linearly with the logarithm of the frequency.



Test Procedure:
The EUT is placed on a non-conducting table 40 cm from the vertical ground plane and 80 cm above the horizontal ground
plane. The test receiver is set to a resolution bandwidth of 9 kHz. Quasi-peak and average detectors were used. Line conducted
data is recorded for both line and neutral.
