Compact Bluetooth Audio Receiver

The QwickZen JS57 adds wireless streaming to any wired speaker, amplifier or vintage stereo system. It accepts Bluetooth audio from a phone, tablet or laptop and outputs through RCA, 3.5 mm auxiliary or optical ports. The unit weighs 115 grams and measures 4.191 cm by 8.7884 cm by 12.3952 cm.

Interface and Range Limits

Bluetooth input uses SBC decoding with HSP, HFP, A2DP and AVRCP profiles. The wireless link remains stable up to 10 metres or 30 feet in open space. Power is supplied from a 5 volt USB source; there is no internal battery. Buyers needing aptX, LDAC or multi-room synchronisation will not find those features here.

Upgrade Path and Fit

This adapter replaces a physical cable between a source device and a legacy audio system. It suits owners of older receivers, powered speakers or projectors that lack Bluetooth but offer RCA, AUX or optical inputs. The jump is worthwhile when you want wireless convenience without replacing a working amplifier. It does not add Bluetooth to a car audio system.

Questions about this item

Which output should I pick — RCA, 3.5 mm AUX or optical — for my stereo?

All three are available on the JS57; choose RCA for most amplifiers, 3.5 mm AUX for portable speakers or car aux-in, and optical for digital input on modern AV receivers or soundbars.

What does the 10-metre Bluetooth range mean when the receiver is placed behind a cabinet?

The 10-metre (30-foot) figure is an open-space maximum; walls, metal furniture and other wireless devices will reduce the practical distance, so keep the receiver in line of sight of your phone for reliable streaming.

Which Bluetooth profiles does the JS57 support for music and calls?

It supports A2DP for stereo music streaming, AVRCP for track control, and HSP/HFP so you can take calls through the connected audio system.
