Bluetooth 4.2 Transmitter

I use this connected to a Samsung smart TV no bluetooth. The transmitter is barely larger than a silver dollar. The manufacturing machining and assembly is flawless. The instructions were well written in simple easily understood language and there is ample and detailed instructions,videos and FAQ's on the Avantree websiteInstallation took a couple of minutes and it paired with non aptX LL bluetooth 4.1 headphones immediately and when they were disconnected then reconnected they did not need to be paired again; they reconnected within 10-15 seconds.The sound transmission to the headphones was perfect. I used the phones for a few hours on the initial startup and there was no cutting out of sound unless I walked down to the back of the house and around a few walls (to be expected). I walked outside and down the yard (didn't measure the distance) but they continued with uninterrupted sound from the TV.I did a bit of research on these transmitters so as not to hopefully be disappointed and have to play the return and try another game. Right off I was impressed that this one used a Qualcomm chip and the reviews around the internet from tech sites ( many Amazon reviews I discount or take with a grain of salt because everybody's experience is their own) were highly favorable and highly rated.I looked for some cons with this product but I can't find any. It checked all the boxes that I needed and thought for the $ it was a bargain.One final thought is the headphones I used were as I said non aptX LL bluetooth 4.1. There was no discernable lag in the sound although with the sound up on the TV while using the headphones there was a faint echo (lag) between the TV and the headphones. This wouldn't bother most people but it did me so I purchased the Avantree Audio Pro aptX LL headphones and the synchronization of sound is perfect.

I'd read a recommendation of this Avantree product on one of the tech web sites which has nothing to sell but free advice. It made me infinitely more aware of what to look for if I wanted to watch my Bluetoothless TV with Bluetooth headsets. I never expected I'd shell out $45 for a gizmo to do this. Their advice was excellent in recommending this model, and I've been happy with the results to have spent that. Other reviewers have commented that there are cheaper ways to do this. But I'm betting that considering the reliability, simplicity in its setup, and quality of the signal, that everyone who buys it will agree it's a good value anyway.If you try hooking it up using the two RCA audio outputs (L & R) on your TV, you may discover what I did. I didn't get any sound to the headsets. So I tried hooking it up using the 3.5 MM output jack, and that worked perfectly (All cables are supplied, by the way.). Perhaps there's a TV setting you need to enable, so that the sound is ported to the RCA outputs? If so, I couldn't find any. Anyway, I've now hooked up two pairs of headsets and they work perfectly, both taking advantage of the headsets' aptX.The range is apparently very good. Although our condo isn't large, it worked perfectly anywhere and on either floor.I'm sorry Dr. Corallo (below) had the experience with Avantree that he did. I've used Avantree's online chat service and they answered my question immediately and thoroughly. I admit that my question was simple compared to his, and it wasn't for a problem I was having. I just had a technical question re aptX and my headsets.So if you don't mind spending nearly fifty bucks on this item by the time you're done paying the sales tax, I really do recommend it. BTW, kudos to Amazon; I don't have Prime and it was delivered the day after I ordered it.Dan Kap,Whittier, CA

This bluetooth transmitter works well. I am using with Sony WH-CH700N Wireless Noise Canceling Headphones, Blue (WHCH700N/L) headphones. Pairing was simple. The sound is clear. If I still have the TV sound on, the sound almost overlays each other. With the TV sound off, it appears perfectly synchronized.Everything is included in the box. It is powered by a micro-USB cable (included). I plugged it into a USB port on the TV. Sound is through a 1/8" phono jack. A cable is included, as well as an RCA-jack splitter, which I used with my TV. The back of the transmitter has double sticky tape. The cables are pretty long (2x-3x as long as I needed).My biggest complaint is its status-LED and power switch. The power switch is tiny, and hard to find. The status LED is bright and blinks blue. This is ok when the TV is on, but is annoying with the TV off. I will try covering it with a piece of tape.Recommended.
