AvantreeOrbit Pro - Bluetooth Transmitter for TV with LCD Screen & Remote Control, Compatible with Optical or AUX Audio Output & Smart TVs, Easy Volume Control for Airpods & Other Headphones

This Transmitter/Receiver is super easy to use. It's smaller than it looks, just a few inches tall, though the top is wide enough to accodate large buttons. The screen makes finding and pairing with your devices a no-brainer.I bought this unit because of the bluetooth capabilities in my Hisense TV were so limited. The Orbit Pro can connect to two bluetooth headphones instead of one, has fewer drop-outs, longer range, no lip-syncing issue (ATPX-LL, low-latency), and allows each listener to pick their own volume level separate and distinct from the other listener.Compared to the other Orbit units, this one has a remote control, supports eARC input and, I believe, has a few more volume levels (15 instead of 10?). I didn't buy this for the remote or eARC input; I simply wanted to make sure I got the latest device with the newest internals. It's 3 years newer than the previous rev.I do get some dropouts. This is particularly noticable if something is in pairing mode (so don't do that while listenting to music). I will report back if I figure out which of my 20 Bluetooth capable devices is interfering. It's not happening that often so I'm not concerned.Avantree seems to have done everything right. It sorta does what you want it to. They just sorta know. For example, I can select a set of headphones on the LCD and see if it's using APTX-LL. You can also adjust the volume in the same way if your earbuds don't have volume controls. There's a remote control that I just put in a drawer since my headphones have volume buttons.I have successfully paired with three over-the-ear headphones and was pleased:- Seinnheiser HD450SE- Ankbit E600Pro- Bose QC 35 IIThe Seinnheiser and Ankbits have APTX-LL. The Bose QC 35 II don't have APTX-LL, and the lag/latency was very noticable (not the Orbit's fault - that APTX-LL is crucial). The Bose went back upstairs for listening to music.Pros:Allows headphones with volume controls to individually select their own volume / listening levelsLooks fantasticLED screen for simple pairingCons:An occaisonal dropout

This Bluetooth 5.0 audio transmitter is an impressive device, especially for anyone looking to connect to multiple sources simultaneously. It efficiently transmits to two Bluetooth devices at once with no noticeable lag between them, which is perfect for sharing audio during parties or gatherings.One minor issue is a slight lag when using both a hard connection and Bluetooth transmission simultaneously. However, this doesn’t significantly impact the overall experience, especially given the variety of input options available.The transmitter is compact and user-friendly, making it easy to pair with your devices. If you’re looking for a versatile and reliable Bluetooth transmitter, this is a great choice.

Ordered Avantree Orbit-Pro Transmitter/Receiver and 2 Avantree NB-18 Ear Buds for TV viewing. I ordered both ear buds and transmitter together with the hope that they would install easily, work consistently without dropping the connection occasionally, and needing to be paired again after pairing was lost all problems common with 3 other transmitters I had purchased. Ease of connection to the TV was simple, pairing the 2 ear buds was simple, range is excellent, ear bud sound is excellent, and while the combination was more expensive than what I had purchased before the value for the money is excellent as the combination works as hoped for 2 old folks that are hard of hearing!

Likes:The display allows you to know what's going on and to have total control over connections. I have four headsets paired and I can easily move between them with no guessing about status. The Avantree also won't steal a device from your smartphone because it thinks it has higher priority (some other TV/Bluetooth transmitters do exactly this.)Supports active connection to two different headsets/buds simultaneously.When using an aptX capable headset the latency is virtually nil. The Avantree will auto negotiate so there's nothing to configure.Has optical input which means you can have both TV speaker audio and Bluetooth audio at the same time. Also, supports optical pass-through to a home theater system. Be aware, however, that, as a practical matter the latency of the speakers vs Bluetooth will likely be different which is very annoying and not really usable. Of course, you can mute the TV and the optical connection will still feed the Avantree and your headset(s).Built-in volume control which is essential for using headsets/buds with a TV on the optical interface.Less good:I've had to reset to factory defaults a couple of times because the device goes a bit crazy. In one case it paired with an unknown device that I did not authorize. I couldn't get it to forget the device either. In another case the volume up/down feature stopped working. In both cases all was well again after the reset.Biggest negative: the buttons need to be back-lit. The thing is unusable in a darkened room. This is especially annoying because the display is back-lit and there's a pulsing glow under the unit - so why not the light the buttons too? It's one of those fails that makes you wonder if the designers ever actually use the product outside their lab.Update:Total latency is a function of this unit PLUS your headphones. The complaints about 1 second latency seem extreme to me. I'm using this device with Sony LinkBud (ear buds) and get about 250mS of latency. It's a bit annoying to have lip-sync off by this much but not a deal breaker, UNLESS you need the speaker audio on at the same time. That's annoying because of the delay/echo between the ear buds and speaker. The only solution to this is ultra low latency headphone/earbuds. BTW, Apple AirPods have the lowest latency of anything I've tried.Finally, the Sony LinkBuds allow you to double tap to increase volume and triple tap to decrease volume. This works directly with the Avantree transmitter volume control (just setup with your Android smartphone) and works great. Otherwise, I'd be jumping up and running to the Avantree to adjust volume - that would be unacceptable.
