Overview

The UGREEN CM123 adds Bluetooth music streaming to a home stereo, powered speakers or a car stereo that has a 3.5 mm or RCA line input. It runs from a built-in battery for up to 8 hours, or from USB power while you listen, and it reconnects to a saved phone when switched on. It suits anyone who wants to play music from a phone through existing wired audio equipment without replacing the amplifier or speakers.

Is it right for you?

  • Suits a home stereo, hi-fi amplifier, powered speakers or car stereo with a 3.5 mm or RCA AUX input.
  • Choose it for music only. It has no microphone and does not handle calls.
  • It is a receiver only. It cannot send sound from a TV or stereo to Bluetooth headphones.
  • The RCA output is line level. It cannot drive passive speakers directly; the destination needs its own amplifier.

Key features

  • Bluetooth 5.0 with EDR, receiver only, using the A2DP music streaming profile.
  • 3.5 mm stereo and left and right RCA outputs, which can be used one at a time or together.
  • Frequency response of 20 Hz to 22 kHz and a signal-to-noise ratio (SNR) of 90 dB at a 16 Ω load.
  • Up to 8 hours on a charge; charges over Micro-USB in about 2 hours, and can be used while powered.
  • Range up to 10 m in open conditions.
  • Compact black housing, 66.6 × 66.6 × 24 mm.

What else you need

  • An amplifier, powered speaker or stereo with a 3.5 mm or RCA line-level input, plus the matching cable.
  • A 5 V USB power source with a Micro-USB cable for charging.
  • A phone, tablet or computer that streams Bluetooth audio (A2DP).

Before you buy

  • Receiver only: no microphone or calls, no transmission to Bluetooth headphones, no optical or coaxial audio and no multipoint. No particular codec beyond standard streaming is stated.
  • RCA is line level, not speaker power. Never connect the outputs to passive speaker terminals, mains or an unknown signal.
  • It has no water-resistance rating. Keep it and the charging port dry and never charge it while damp.
  • Do not crush, puncture or charge a swollen, wet or unusually hot unit. Do not leave it on a hot dashboard or in direct sun.
  • In a car, pair and set the volume while parked.
  • Walls, metal and 2.4 GHz interference reduce range and can interrupt playback.
  • Start at low volume and limit listening time.
