FiiO has unveiled a pair of Bluetooth devices for Hi-Res audio fans – the portable BTR11 Bluetooth audio receiver with headphone amp and BT11 Bluetooth audio transmitter. The BT11 adds BT LE, Snapdragon Sound, LDAC, and aptX Lossless to older devices, while the BTR11 adds BT LDAC playback to wired headphones.

FiiO has released the BT11 Bluetooth transmitter and the BTR11 receiver to add Hi-Res audio to older devices and wired headphones that do not support LDAC wireless audio.

The BT11 transmitter utilizes Bluetooth 5.4 to support high-resolution audio codecs beyond the standard SBC codec - aptX, aptX Adaptive, aptX HD, aptX LL, aptX Lossless, and LDAC. The transmitter uses a QCC5181 SoC with a Qualcomm Kalimba DSP audio processor to support the transmission of 96 kHz 24-bit audio using the aptX Adaptive and aptX Lossless codecs and 48 kHz 24-bit audio using the LDAC codec.

The transmitter can use LE Audio to reduce transmission latency to under 50 msec. for more responsive gaming when connected to game consoles such as the Nintendo Switch. The BT transmission can reach up to 164 ft. (50 m) away. The BT11 measures 1.1 x 0.8 x 0.4 in. (28 x 21 x 9 mm) and weighs 0.1 oz (3 g). The USB-C port can connect to USB-A devices using the included USB-C to USB-A adapter. It comes in black or silver with an MSRP of 7,700 yen (~$49).

The BTR11 receiver uses a BES2700 BT 5.3 DAC coupled to a headphone amplifier with independent left/right amps to eliminate channel crosstalk when decoding LDAC audio. The output has a frequency range of 20 Hz to 45 kHz with a SNR ≥ 101 dB and THD+N < 0.008% (1kHz/-3dB@32Ω). A built-in microphone with noise-reduction turns wired headphones into wireless headphones capable of taking phone calls.

The battery powers 3.5mm headphones with up to 45 mW of power at 16Ω with a THD+N < 1% for up to 8.5 hours in LDAC mode or 15 hours in AAC mode. The battery fully recharges in 1.5 hours with a USB-C power source. The BTR11 measures 2.2 x 0.7 x 0.6 in. (55 × 19 × 14.6 mm) and weighs 0.5 oz. (13 g). It comes in black or white with an MSRP of 3,520 yen (~$22).

Both FiiO devices are available in Japan. Readers in America who want a 2-in-1 Bluetooth receiver/transmitter with aptX codec support can buy the AirFly Pro on Amazon.
