Giveet Bluetooth Transmitter Receiver for TV to Headphones, 2-in-1 Bluetooth V5.0 Adapter w/Volume Control, Optical RCA AUX for PC/DVD/MP3/Home Theater, 25Hrs Playtime, Pairs 2 Devices Simultaneously

I've been using the product extensively for about a week now. So far it works really well. - The controls might be confusing at first but as long but using the LED light as a "guide" it becomes straightforward. The device itself has its own volume control and a separate button for paring to two devices at the same time. - Its paired with all of my Bluetooth speakers and I've had no issues connecting 2 devices at the same time. - I'm very happy with the sound quality. It has a very flat frequency response so the sound quality is going to depend on how your speaker/headphones has been tuned. - Battery is very long. I don't know if its "25 Hours" as claimed but I have on throughout my shift (at least 9 hours) before I switch it off. I never have to think about it. It supports APTX Low Latency, but I don't have anything that uses that codec so I wasn't able to test that. Everything I have uses AAC or SBC so in my case I expected some video/audio sync delays.

Superb, used for sending tv audio to Bluetooth head phones. It was easy to setup and has two inputs one is a optical input which is a plus, the battery life is very good and the best of all it automatically shuts down when the headphones are disconnected.

I'm only using this as a Bluetooth transmitter to some Jabra earbus via the optical output of a SKY Q Minibox and the AUX (stereo min-jack) output of a desktop computer. It's pretty easy to set up and pair, and the controls are very simple - On/Off, volume +/-, pair, and switch between optical and AUX. Once paired, connection is automatic and a status indicator light at the front shows what's happening. It comes with a full complement of cables and a tiny but detailed printed instruction manual, which even has specific instructions for use with hearing aids, Amazon Echo, Google Home devices, and Airpods. Given a decent cable, the AUX input sound is crisp & clear, and the optical input sound is very good (48KHz, 24 bit). My earbuds don't have the aptX low-latency Bluetooth codec, so the default SBC codec is used - this gives a noticeable (~220ms) lag between vision and sound, but I think it's OK unless you're gaming. For gaming, aptX Bluetooth headphones are a must. This device looks almost identical to the Avantree TC417 which costs £5 more and has the same layout, functions & features, so I suspect they use the same electronics. The only significant difference I can see is that the Giveet comes in a plain box and support is via email, whereas the Avantree comes in a glossy printed retail pack and has website support. So far, so good.

Brilliant device, I use this BT sender from my Smart TV which is tethered to my iPhone At first I had a buzzing noise in the headphones but my mistake I had not set the TV sound output to PCM After contacting the supplier who replied in hours and said change the output to PCM it worked straight away. Love the unit, easy to connect, battery last ages and you can adjust the volume A small compact unit I use with optical input. 5 star rating and would recommend and buy again.

The unit was was easy to set up and use. I am now playing my ancient akai reel to reel through Bluetooth speakers, and it sounds great.

I'm using this on a 4 year old Hitachi TV in the bedroom. I've used it through the headphone socket, the optical connection and the RCA connectors. They all work well, the only thing I noticed wrong was the TV remote wouldn't adjust volume through the optical connection - but that may be down to the TV. So far used it with 2 different Bluetooth headphones, both worked with no problems - Bluetooth connection was really easy to set up. Battery life is good, plus I can charge it via the TV's USB socket, so can still use it while charging. Can't think of a single negative thing to say about it. It's good value as well, especially when you consider how much extra manufacturers charge for Bluetooth TVs.

This device would be ok for just audio, however when used as a TV output for headphones etc the term 'low latency' does not apply. There is a definite lag between the picture on the TV and the sound arriving in your ears. I found this annoying especially as I am deaf so wanted to use this together with the TV speaker itself for my Wife while I listened on headphones. Even in my deafness I could hear two slightly unsynchronised sound outputs, while looking at actors on the TV whose lips were not synched to the sound I was listening to on the headset. The sound quality itself was OK but that is more to do with the headphones than the device itself.

Received today and set up in a couple of minutes after I charged it. But it only took half an hour to fully charge so it must have already been almost fully charged on arrival. Used in TX mode with my Hisense A6250 television via Toslink/Optical and Cowin E-7 bluetooth headphones. As soon as both were turned on they both went straight into pairing mode and paired in a few seconds. Overall the sound was a little too deep which I cured by turning off surround sound on the TV. No latency that I could see. At first I muted the TV but I didn't like the mute symbol being in the corner of the screen so I then just turned the sound volume all the way down which worked about the same as muting. A few shortcomings which might be important for some but not for me: (a) When used in SPDIF (Toslink/Optical) mode the "+" and "-" volume buttons don't work which probably means the next track and previous track functions which use the same buttons won't work either. So headphones which have their own independent volume control is a must - Apple Air Pods are out! Such a set up is handy though for people who have the volume at different settings possibly listening on both headphones and tv speakers.. I haven't tested the connections for two sets of headphones at the same time though. (b) No Dolby, only PCM which needs to be set as such in the TV settings. (c) The RCA connection is RCA to Aux 3.5mm Overall it works for me so 5 stars. Now I won't disturb my neighbours with horror film screams at a high volume!

Ottimo prodotto, pienamente funionante, il bluetooth raggiunge anche un piano di distanza. Facilissimo da collegare a qualsiasi dispositivo Ottima anche la durata della batteria.

le sont légèrement décalée autrement fonctionne très bien

Este producto fue el que seleccione después de probar varios productos que no me dieron el resultado deseado. Además creo que es de un precio adecuado.

Según lo anunciado en la descripción del producto, quería un adaptador bluetooth 5.0 para mi PC para conectar dispositivos bluetooth con el PC como cascos, teléfono etc.. y en realidad no lo hace. Por lo tanto no me sirve y la valoración del producto esta basada en este hecho, no si vale para las otras funciones que dice que hace, cosa que no he probado.

I bought 2 units of this item to pair up as 1 as a transmitter connected to my Yamaha digital piano and the other 1 as the receiver connected to my headphone, the result was phenomenal, I could not hear a lag and noise level was very minimum. I will duplicate this setup for my video production on site as 1 connect to camera body and the other to my headphone so I can more mobility moving around. I am quite satisfied with this product. Regarding the bluetooth connectivity, you still need an aptx type of bluetooth headphone to achieve the best result.
