Giveet Bluetooth V5.3 Transmitter Receiver for TV, 2-in-1 Wireless Transmitter Adapter for TV Airplane PC MP3 Gym, Bluetooth Receiver for Wired Speakers Headphones, No Delay, Pair 2 Devices, 16 Hours

Been using it for 2 weeks now and still on the original charge (I did top the charge when I got it). I have been using it nearly every day for over hour at a time and closer to 90 minutes. I think I have gone past the 14 hours. No problems with sync but I use it on the headphone socket of a amplifier which all my devices go through. I have tried it with 3 bluetooth headphones/earphones just fine as well as turning wired earphones into bluetooth ones too. This was in receiver mode and connected to my phone.. Easy to use. Press down on button to turn it on (LED turns blue), then double tap it again to start pairing (LED flashes blue). I found it is best to turn the bluetooth on the headphones first then double tap on the gadget. It seems to find and pair quicker. It then turns a solid blue. Make sure it is turned off when not in use by pressing the button down otherwise it will stay on all the time. I have just noticed that not all the red LED lights on my one go on when charging or in standby, I have a pair of headphones coming today so decided to charge it up full again and just noticed the LED's.. I believe there should be 4 LED's making the circle and only get 3. I still get 4 blue LED's when bluetooth is on. As I only charged it once, it may have always been like that. One of the photos show the red light on and not quite a complete circle but got a full blue circle when in operation. Comes with a micro usb charging cable (not too long but seen shorter ones). 3.5mm to 3.5mm audio cable to connect to headphone socket as well as a audio adapter to turn the 3.5mm audio cable into red and white phono plugs on one end. The adapter is needed for receiver mode so it can connect to aux input on a Hi Fi amp and turn a Hi Fi into a bluetooth capable one. If the aux input is a 3.5mm socket then the adapter is not needed. The manual is good and explains things well. Shame about the red LED but otherwise a cracking good gadget.

I bought this device because I wanted the convenience of Bluetooth for old equipment that didn't have that facility, especially for my TV's. I have found it simple to use and reliable and I can now watch TV unobtrusively wearing my Bluetooth headphones. It has the bonus of being able to RECEIVE Bluetooth, so you can blast sound from your phone through old amplifiers and other sound devices by plugging it in to the AUX socket. Its' one catch is that it has no facility for deivices with an optical audio socket, such as Samsung TV series 7 and above. However I got round this by plugging it into my cable TV set top box instead. You can also purchase a second device that converts optical to phono and plug the BTI-018 into that. The BTI-018 does exactly what I wanted it to do and I'm very happy with my purchase.

I use this device in transmitter mode to connect an old Pioneer turntable remotely to the power amp. Connection was simple and trouble free and performance is adequate. Frequency response seems very flat compared to a direct hard wired connection but it does the job at a very reasonable price and to get something better means paying a great deal more. So, good value.

Yet another fulfilled by Amazon product that isn't as described. I bought one and my wife bought one in order to send the sound from the TV to some remote speakers using one as a transmitter and one as a receiver. The description stated: "Giveet BTI-018 supports the codec of aptX Low Latency in Both TX & RX modes", this isn't true; the receiver doesn't support low latency apt-x, it just supports SBC. Apart from that, the device works well and you can pair two together, sound quality is very good, it just isn't as described otherwise I would have rated it higher. Please be aware that to benefit from Apt-X your paired Bluetooth device needs to support Apt-X as well. There is a newer version of Apt-X coming out called Aptx HD which is supposed to give even higher quality audio. Amazon or the supplier may correct their description after this review, just bear that in mind if this review no longer makes sense.

Recently used this on an 8 hour flight to the states, was such a comfort as they give you such clunky headphones, I was able to plug this into the in flight headphone Jack and watch movies on the plane with my AirPods and could lye back & rest my head with no clunky headphones, I didn’t think it would work as the Jack insert on the plane had two ports on the end of the headphones they provided a large and a small so that threw me off, However I plugged this into the larger port & it worked. No interference & very easy to pair. The final thing before leaving a review was if it works with my home tv, I have noisy neighbours and I struggle to watch tv at night with the thumping sounds from them walking up and down in the apartment above me, I paired this to my tv, no issues and watched tv in bed my AirPods. Such a light, compact device, my favourite gadget that I wouldn’t be without.

This is a really easy to use device. I connected it to the outputs on my Teac amp with the supplied leads and now bluetooth the sound direct to my LG soundbar system wirelessly, which meant I could take out my wired in Bose speakers and sub that had started getting in the way in our newly redecorated lounge area. The sound from the LG soundbar and connected subwoofer is perfectly acceptable. It takes barely a second or two to BT back to the soundbar whenever the button is switched on, on the device. The sound level is then controlled using my soundbar remote. All very simple, all very tidy, all very good. If you have BT surround speakers, this would work with those too!

I bought this a couple of weeks ago to take receive two devices by Bluetooth (PC + tablet) and take them via its 3.5mm jack output to speakers. It was fairly simple and easy to connect and seemed to work for a bit. But it cuts outs out, drops the connection and it's highly unreliable - you're in the middle of a Zoom meeting & suddenly the audio goes - not good! I'm scrapping it and will find a different solution.

Ottimo. Si connette facilmente e funziona perfettamente sia in ricezione che in trasmissione

Die Akkulaufzeit ist klasse (ca. 10 Stunden). Ladezeit ist sehr kurz. Koppeln mit Bluetooth-Kopfhörer dauert ca. 1 Sekunden (bei meinem Vorgängermodell dauert das schon mal 30 Sekunden). Ich würde den Artikel wieder kaufen.

Mi coche tiene entrada jack auxiliar y el bluetooth solo sirve como manos libres, con este cacharro puedo poner la musica del telefono, spotify y demas perfectamente.

Petit appareil qui se fait discret. Le mode Aptx apporte une qualité CD. La synchronisation se fait rapidement. Cela fait maintenant plus d'1 An que j'en posséde une paire pour dupliquer le son de mon poste de radio analogique dans le salon sur une enceinte active dans la cuisine, la fiabilité est toujours la. Il y a quand même une petite latence mais pas trop gênante.

This BTI-018 bluetooth rx/tx works well when in a stable position during operation. It does transmit to two bluetooth devices simultaneously. Tested with my iPhone as the sound source I was unable detect any difference in sound quality between connecting my headphones to directly to my iPhone's native bluetooth tx and connecting to the BTI-018 plugged into the iPhone's lightning connector with the iPhone's headphone/lightning adapter. I originally purchased this device as a possible solution to being able to listen to music in sync with a running partner. It was small and light enough to fit a small belt pouch (yes ... fanny pack) and initial sound quality and sync seemed it would be an ideal solution. Unfortunately, even while staying within a 10 meter range of said partner, the signal would occasionally skip in one or both headphones and begin to degrade through stutter to silence requiring a disconnect/reconnect cycle on the headphones to rectify. While the product didn't address my original intentions, it does perform well and as described when using it while stationary. Customer support from this seller was quick, relevant and offered not only good suggestions on a few reasonable troubleshooting activities but also a recommendation for a product that should fit my needs better and a more than fair and generous reimbursement solution.
