FiiO BTR15 blue

The FiiO BTR15 headphone amplifier delivers an output power of 340mW (when using the balanced output). With this level of power, the BTR15 can effortlessly drive most large headphones, making it more suitable for use with a computer/laptop. That's why FiiO has implemented a manual switch on the device, allowing you to toggle between use with a computer, a pure wireless connection, and a connection to your phone. The converter is capable of full MQA and PCM decoding up to 384kHz / 32-bit and DSD256. When connected via Bluetooth, you can also set the so-called PEQ, or Global Parametric Equaliser, on the amplifier. This is a unique feature developed by FiiO that lets you adjust various equaliser parameters, gain, and other device settings for all possible uses. The body is traditionally crafted from a combination of aluminium alloy and toughened glass. On the front, there is an OLED display where you can adjust basic functions. On the bottom, you will find two headphone outputs: a 3.5mm single-ended output and a 4.4mm balanced output.
