Bluetooth receiver for home stereo

The KAIY C53 adds wireless streaming to any system with RCA or 3.5 mm inputs. It accepts audio from a paired phone, tablet or TF card and plays through existing speakers. The adapter suits owners of older receivers, powered speakers or car stereos who want cable-free playback without replacing their equipment.

Sustained wireless link up to 33 FT

The receiver maintains a stable Bluetooth connection across a 33 FT range during continuous playback. Automatic reconnection restores the link after power cycles so music resumes without manual pairing. NFC tap-to-pair works with compatible devices for an even faster start. The 3D sound mode processes audio continuously without audible distortion at full volume.

Interface limits of RCA and 3.5 mm analog outputs

Audio leaves the adapter only through stereo RCA or 3.5 mm jacks, so multichannel or digital signals are not supported. The TF card slot reads local files but does not expand internal storage. NFC pairing requires an NFC-equipped source device; phones without that hardware must use standard Bluetooth pairing instead.

Questions about this item

Does the C53 run warm or draw much power during all-day streaming?

The compact 2.71 in x 0.94 in x 2.71 in adapter draws minimal power from its USB supply and stays cool during continuous use.

Which cables or ports must I already have on my amplifier for the C53 to work?

Your amplifier needs either RCA line-level inputs or a 3.5 mm auxiliary jack to accept the included audio cables.

Will the C53 pair reliably with a phone that only supports older Bluetooth versions?

Yes — the C53 maintains a stable 33FT link and reconnects automatically each time it powers on.
