KAIY C52 Bluetooth Receiver NFC RCA AUX 33FT

What the C52 receiver does

The KAIY C52 adds Bluetooth streaming to any stereo that has RCA or 3.5 mm inputs, letting you play music from a phone or tablet without running new wires. It also reads audio files directly from a TF card, so you can listen even when no Bluetooth source is nearby. The tiny 2.71 in square footprint means it tucks behind most equipment racks without crowding other gear.

Build and daily connections

A plastic shell houses the circuitry and exposes RCA sockets plus a 3.5 mm jack, covering 99 percent of the speaker and amplifier combinations found in home and car systems. Power comes from an external USB cable, so placement depends on a nearby port or charger. The stated 33 ft wireless range keeps the link stable across a typical living room, and automatic reconnection restores the link each time the unit powers on.

Accessories and software behaviour

The box includes the RCA and 3.5 mm cables needed for the two most common analogue inputs, eliminating a separate cable purchase. NFC tap-to-pair works with compatible Android phones, cutting the usual menu-driven pairing down to a single touch. A 3D surround mode can be toggled on the device to widen the soundstage for music, movies or podcasts.
