CTOnews.com learned that in June this year, Feiao released the THX portable decoding ear amplifier BTR7, which uses the seventh generation hard core machine armor design language, and is equipped with a 1.3-inch IPS and color display screen on the aluminum alloy body through a full-fitting process.

Officials say that BTR7 uses a complete audio architecture comparable to that of HiFi players. DAC + low-pass filtering + ear amplifier driver ensures the details and dynamics of audio; the DAC part uses ES9219C launched by two ESS to effectively reduce channel crosstalk and improve separation; and ear amplifier part uses THX AAA ear amplifier technology to form a fully balanced ear amplifier driver, which nearly doubles the output power and increases the balanced output power by more than 30% compared with DAC direct push.

In the Bluetooth part, BTR7 uses Qualcomm QCC5124 Bluetooth chip, supports LDAC / aptX HD / aptX Adaptive HD Bluetooth coding, as well as AAC / SBC and other conventional Bluetooth coding.

In the wired part, the USB decoding uses XMOS's XU208, the decoding capacity can reach 384K / 32Bit, and it can also support USB1.0 driver-free. With the playback software with MQA decoding function, it can achieve 16 times deployment.

BTR7 is a Bluetooth decoded ear amplifier that supports wireless charging, compatible with Qi protocol, built-in 880mAh high-capacity battery, and can listen to songs continuously for up to 9 hours when fully charged.

In terms of interface, BTR7 is equipped with 3.5mm / 4.4mm headphone interface, which can output single-ended and balance signals respectively.
