Review: iPod classic bluetooth w/ Bose Revolve & Sonos speakers - easy, no latency, no skips, no static - Very seldom does "plug and play" work as seamlessly as promised . . . except this does! Using this to give an oldie but goodie iPod classic the ability to Bluetooth connect and play through a couple Bose Revolve and Sonos speakers. Seriously, this took less than 5 minutes to set up. Plug it into the iPod's headset jack, then plug it into an outlet. It came with about a 75% charge, but I wanted it to always be plugged into a power source since I plan on leaving it in place. Toggle the on button to on, then push the sync button on this transmitter and on the first speaker. Connected easily. Do the same with the second speaker. Connected just as easily. At this point, I paired the two Bose speakers with each other so they could play in either party or stereo mode. No matter which mode they're in, they play in sync with each other without lag, latency or static. So far, I've used this almost everyday since initial set up and there was never any issue with needing to re-pair or re-sync - - - all devices remembered each other (recognizing it as Avantree) and picked up just where they left off. It honestly took me more time dealing with the physical aspect of cord managing the charging cable (fishing the cable behind furniture so it's out of sight) than actual set up of the device. Comments: - note there is an actual on/off switch on the device. It's tiny and on the side of the transmitter, but that needs to be "on" in order to function. I don't know if it's necessary, but I also turn it off when I'm not using it just so it's not always actively sending out a signal. - happy surprise that there are also volume control buttons right along side the on/off switch. I don't need those in my situation, but if you're travelling or are using this as a portable transmitter, this is a handy bonus - it's amazingly teeny - - - about the size of a flash drive and smaller than an old school pack of gum - comes with a 2 prong headset jack, presumably for airplane use, but I think most airlines have gone to the single jack input as I honestly can't remember the last time I saw a double jack on a plane. - comes with a charging cable, but not a wall plug. - if you're taking this with you, it also comes with a compact case that everything fits into nicely
Review: Ideal for flying with bluetooth headphones; a well thought out product - Why did I buy this product? Because I make international flights on a regular basis. For travel, noise canceling headphones are a must-have, but most are now bluetooth. Unfortunately, most cattle class seats have infotainment systems that only provide mini-jack outputs. Enter this device as the perfect solution! At least in my opinion. This device allows me to plug-in to the output jack on an aircraft without the inconvenience of wires. It has several domestic uses, specifically provided a bluetooth interface to older audio equipment, PC's that don't have bluetooth, and (some) tablets. Does it work? Yes, no reservations. Fully charged, the battery was only 50% drained at the end of a 10 hour flight to London from Phoenix, AZ. I used this device in conjunction with my iPad mini, the aircraft infotainment system and even my PC at home. Binding was fast and effortless. Recommend you read the instructions because although binding and unbinding is easy (and works) the unit itself has a minimum of controls and you need to know what you're doing! I really can't speak to quality or range, but at least up to around ten to fifteen feet it was working fine, and sound quality was excellent without drop-out or interference. Can I listen to music while the unit is attached to a charger? Yes you can. This was a worry for me, especially since I forgot to recharge before the return trip. So I attached to a USB-C power bank and absolutely no problem, throughout charging, the unit worked fine. BTW, many airlines seem to be banning the use of power banks on or onto their aircraft - just another nuisance to check on before you fly! Do I know how much power is left? Yes, there are 4 white LED's which tell you how much charge you've got on the device. The top-most illuminated LED flashes until the next level is reached or the unit is fully charged. Finally, can two people listen to the same audio? Yes, my wife and I watched a video on the plane, with both of us wearing Bose NC headphones in bluetooth mode. The unit provides two, simultaneous links so for me that was the final box ticked. Some widgets are hard to use, but this one is well thought out and easy.

## Questions & Answers

**Q: Will this work with a regular TV?**
A: As long as your TV has an AUX audio output jack, the Relay will work with it.

**Q: Will I get audio lag or lip-sync delays with my headphones?**
A: Your headphones must support either aptX Low Latency or aptX Adaptive in order to eliminate audio latency. Please note that most true wireless earbuds (such as AirPods) do not currently support these audio codecs.

**Q: How are the volume levels?**
A: You should be able to reach sufficient volume levels by adjusting the volume on both the Relay, your headphones, and / or the audio source.

**Q: How long does it take to fully charge the adapter?**
A: It only takes 1.5 hours to fully charge the adapter.

**Q: Can I connect my phone to the Relay via Bluetooth?**
A: No, as a transmitter, the Relay is designed to only connect to audio devices (such as your headphones or AirPods) via Bluetooth.
