Questions about Ugreen CM403

Yes

Yes, a CD player in the car can be connected via Bluetooth by using a Bluetooth adapter. Such an adapter can convert the analogue audio output of the CD player into a Bluetooth signal, which can then be sent to a Bluetooth-enabled device. Alternatively, you can also use a CD player with integrated Bluetooth, if available.

It probably needs to be reset and reconnected to the new phone.

You can connect the UGREEN CM403 to a plasma TV to Bluetooth headphones by using it in transmitter mode. Here's how: 1. Connect the CM403 to the TV's audio output (if it has a 3.5mm jack) using a 3.5mm cable. 2. Switch the CM403 to transmitter mode. 3. Turn on your Bluetooth headphones and put them in pairing mode. 4. The CM403 will automatically pair with the headphones, allowing you to stream audio from the TV to the headphones. Ensure your TV has a compatible audio output for this setup.

The Ugreen CM403 can be used as a transmitter to send audio to a stereo system with a Bluetooth system. However, compatibility depends on the specific Bluetooth version and the supported audio codecs of the stereo system. The CM403 supports the AAC and SBC codecs, which offers a good chance of compatibility. On the question of whether the signal can be received with another CM403: Yes, this is possible. You can use the CM403 as a transmitter and receive the signal with another CM403 in receiver mode. The circuit "Phones out => CM403 => Bluetooth => CM403 => Aux in" should work, as the CM403 can work both as a transmitter and as a receiver.

Yes, you can connect two Bluetooth headphones to this adapter at the same time. In transmit mode, the device can be connected to two Bluetooth receivers to output audio simultaneously.

Yes, you can connect your older Sony headphones (TMR-RF855R) via Bluetooth to the Ugreen CM403 adapter and your Samsung TV (UE55DU7172UXXH). The Ugreen CM403 is a 2-in-1 Bluetooth adapter that functions as both a transmitter and receiver and is compatible with devices with a 3.5 mm AUX connection. You do not need an RCA-HDMI adapter as the CM403 works directly via the 3.5 mm connection. Note, however, that the CM403 is not compatible with AirPods Pro 2, but this should not be a problem with your Sony headphones.

Yes, the sound from a TV without Bluetooth can be transmitted to a Phonak Audeo hearing aid with Bluetooth using this adapter. The adapter acts as a transmitter and makes it possible to send the sound from a TV to the hearing aid via Bluetooth. Make sure that the hearing aid uses the supported Bluetooth codecs (e.g. SBC) to ensure a stable connection.

The UGREEN CM403 Bluetooth Audio Adapter is compatible with analogue headphones such as the Sennheiser Momentum 2 to connect them to a mobile. Here are the details: - The adapter supports connection via a 3.5mm AUX cable, which makes it possible to convert non-Bluetooth-enabled devices such as the Sennheiser Momentum 2 into Bluetooth-enabled devices. - In receiver mode (RX), the adapter can be connected to the headphones to receive music or other audio signals from a mobile phone. Thus, the UGREEN CM403 can be used to connect the Sennheiser Momentum 2 to a mobile phone.

Of course, there is a delay if you are listening to your own microphone recording.

I used it on the Zurich-New York flight, there and back, without recharging.

This setup allows you to add Bluetooth functionality to your non-Bluetooth speaker, enabling wireless audio streaming.

Yes, it also works with the Ipad (we went on holiday that way), regardless of the medium. It even works with a USB-C adapter on my Iphone 15. The volume is always controlled for both headphones at the same time, i.e. you can't turn down one headphone.

Yes, you can

Yes. Actually I'm using mine for almost a year now like this (charging it while in use).

No, that will not work. The CM403 is only made for audio transmission (jack plug). For video streaming you need an HDMI plug, something like Google ChromeCast.

9cm in total (5cm for the case and 4cm jack)

Is the battery charged and is the switch in the correct position? If you follow the operating instructions, it should actually work. https://www.manualslib.de/manual/1032603/Ugreen-Cm403.html

Yes, it works perfectly in the aircraft if it has a 3.5mm connection.

I have to charge it regularly. I have the impression that the battery life is rather short. However, I have not tested it concretely.

Ugreen's "CM403 (Transmitter & Receiver)", which is a Bluetooth audio adapter, does not appear to be specifically designed to be compatible with Bang&Olufsen BeoPlay A8 or BeoSound 8. For BeoSound 8, users have found it difficult to find Bluetooth adapters compatible with the 30-pin connector, as these adapters do not provide the data presence expected by the dock. For BeoPlay A8, there is no specific mention in the available sources that the Ugreen CM403 adapter would be compatible. It is recommended that you check directly with the Ugreen manufacturer or consult the product specifications for precise compatibility information.
