Turn wired speakers wireless

The KAIY C52 adds Bluetooth and NFC streaming to any stereo that accepts RCA or 3.5 mm inputs. It also plays audio files directly from a TF card. The adapter suits listeners who want wireless convenience without replacing their existing amplifier or powered speakers.

Check your amplifier inputs and power source

Your system must provide a free RCA pair or a 3.5 mm auxiliary jack for the audio connection. The adapter draws power from a USB supply, so a nearby USB port or wall charger is required. Buyers whose equipment lacks these connections or a convenient USB outlet cannot use this device.

Stable streaming at room distance

The manufacturer rates the wireless link at 33 ft, so music continues through walls and furniture during extended listening sessions. Automatic re-pairing restores the connection after power cycles without manual steps. The 3D surround mode processes audio continuously rather than only for short bursts.

Questions about this item

What cables and accessories come with the KAIY C52, and what must I buy separately?

The C52 includes the receiver unit. You will need to provide a USB power source and either an RCA or 3.5 mm audio cable to connect it to your speaker system.

Should I choose the KAIY C52 over another capacity or version?

The C52 is a single model with no alternative capacities or versions listed. Choose it if you need a 2-channel Bluetooth receiver with NFC, TF card playback, RCA and 3.5 mm outputs, and a 33 ft range.

How does the 33 ft range perform when the C52 is installed in a real stereo cabinet?

The 33 ft specification is a line-of-sight figure. Inside a cabinet or through walls the reliable distance will be shorter, but automatic reconnection after the initial NFC tap keeps daily use simple.
