UGREEN 90748 CM596 Bluetooth 5.3 AUX Receiver, 15H

Overview

The UGREEN CM596 adds Bluetooth music and hands-free calls to a car stereo or speaker that has a 3.5 mm AUX input. It has its own battery with up to 15 hours of playback, a built-in microphone, and reconnects to a saved phone when switched on. It suits a car or home speaker with an AUX socket and no Bluetooth of its own.

Is it right for you?

• Suits a car stereo, powered speaker or home stereo with a 3.5 mm line-level AUX input.
• Choose it if you want battery operation, so it does not need a USB port while playing.
• It uses SBC and AAC codecs. If your phone supports aptX or LDAC and you want them, a different receiver would suit better.
• It is a receiver only. It cannot send TV or stereo sound to Bluetooth headphones.
• Not for speaker-level or microphone-only sockets.

Key features

• Bluetooth 5.3 receiver with SBC and AAC codecs.
• Built-in microphone for hands-free calls on phones that support them.
• Two phones connected at once, one playing at a time.
• Up to 15 hours of playback per charge and about 200 hours on standby.
• Charges over USB-C in about 2 hours.
• 3.5 mm AUX output. Black housing.

What else you need

• A stereo or speaker with a 3.5 mm line-level AUX input and its own amplifier, plus a 3.5 mm cable if the receiver does not plug in directly.
• A USB-C cable and a 5 V USB power source for charging.
• A phone or tablet that streams Bluetooth audio.

Before you buy

• Receiver only: no transmission to Bluetooth headphones, no aptX or LDAC, no optical or RCA output and no USB data audio.
• It has no water-resistance rating. Keep it and the USB-C port dry and never charge it while damp.
• Pair, mount, choose sources and set the volume while parked. Hands-free calling does not remove your attention or legal responsibilities.
• Do not leave it on a hot dashboard or in direct sun. Do not crush, puncture or charge a swollen, wet or unusually hot unit.
• Connect the 3.5 mm output only to a headphone or AUX line-level input, never to speaker terminals, mains or unknown signals.
• Walls, metal and 2.4 GHz interference reduce range and can interrupt the link.
• Start at low volume and limit listening time.
