There is no buttons on the left side.
The encephalon of the FiiO BTR1K is a Qualcomm QCC 3005 bluetooth 5.0 dual way chip that supports Bluetooth depression liberate energy (LE) together with regular Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR), pregnant the FiiO BTR1K has a stronger, to a greater extent than stable wireless transmission at 10 meters inward directly occupation of sight. The Bluetooth 5.0 chipset also provides the latest bluetooth profiles: HFP v1.7, A2DP v1.3 together with AVRCPv1.5.
Having the QCC 3005 microcontroller integrated inward the FiiO BTR1K way you lot also larn back upwardly for iPhone AAC together with aptX Low Latency thence the FiiO BTR1K tin stream high Definition sound to both Android together with iOS devices (in sync amongst video inward Android only) . You tin twosome the BTR1K via bluetooth or NFC but you lot tin also connect the Fiio BTR1K via OTG cable wire to an OTG-enabled smartphone.
The FiiO BTR1K headphone amplifier features the same AK4376A DAC you lot arrive the FiiO BTR3 24-bit DAC Amp so you lot tin also claw upwardly the BTR1K amplifier to a laptop or estimator every bit a 16-bit/48kHz USB DAC to meliorate your computer's audio.

Oddly enough, charging fourth dimension is the same for both the BTR3 together with the BTR1K at ninety minutes. Size, wise, the FiiO BTR1K measures 5cm long, 2.4cm broad together with 1cm thick. The BTR1K weighs twenty grams.
When powered on, the FiiO BTR1K enters pairing way automatically but you lot tin manually forcefulness pairing way past times asset the minor push to a higher identify the book rocker for vi seconds.

The FiiO BRT1K does a adept project at amplifying the sound coming from a smartphone without distorting it thank you lot to generating a high signal-to-noise ratio (120dB) amongst rattling trivial racket flooring (less than 2uV).
The output ability is 25mW at 32Ω and 45mW at 16Ω thence the FiiO BRT1K amplifier tin piece of work amongst headphones/earphones amongst high impedance rating inward the 100 ohm range.
