TROND Bluetooth Transmitter and Receiver for TV iPod PC, Dual Link AptX Low Latency, 500mAh Large Battery, Digital Optical TOSLINK and 3.5mm Aux, Specially Designed for TWO Wireless HeadphonesIn the box.The Bluetooth unit, phono to jack adapter, USB micro to USB 1 (charge lead), Jack to jack lead, male to male jack adapter Tosh link optical cable and instructions.Power.It can be powered from the internal rechargeable battery or via a USB power source.How it works.This unit can take an audio output signal and turn into a wireless Bluetooth signal. It can also receive Bluetooth signal and via one of the cables link to a system that has no Bluetooth.Applications.I have two applications for this. One is to take my TV signal to my Bluetooth headphones which give me better quality sound than the built-in speaker. Also a headphone cable would need to be very long and largely impractical to implement. Secondly it can take the music via Bluetooth from my phone and tablet and using the supplied cables link it into my hi fi system so that I can play my music downloads over my speakers. My hi fi is very good quality but Bluetooth was not around when was designed.Set up.It can be a bit fiddley to get it right but the instructions are quite easy to understand and follow. After about half an hour with the system I managed to connect it to my hi fi and Bluetooth my music from my table to it. I also quickly got my TV sound onto my Bluetooth headphones – just don’t forget to change the mode switch on the side from TX to RX (I did not the first time and wondered why I had no sound! – it does help to read the instructions!Overall.A nice little gadget that serves a really useful purpose. Have my downloaded music playing on my hi fi is great and the quality is not bad. It is not as good as a CD but quite close. I am very pleased with the results and having an internal; battery means you don’t need a lumpy power supply. This is a neat solution.

After a great deal of research into various options I finally settled on this one, not without some misgivings.My worries were unfounded.Neatly packed, everything present. Really clear instruction leaflet solely in good English - Yay !Promises of 30 day money-back offer and 18 months warranty.We have a typical problem with TV listening where my hearing is well inferior to my wife's.Our old Samsung TV has no Bluetooth and I wanted to use my AKG Y50BT headphones.The existing Yamaha sound-bar is connected to the 'optical out' socket on the TV and does not mute the audio. It also has it's own remote for volume and mute etc.This means that simultaneously connecting headphones via the 3.5mm audio-out socket on the TV automatically mutes the TV speakers, but allows the headphone volume can be controlled independently via the TV remote.Voila !I plugged the Trond into the audio-out socket on the TV, carefully paired the AKG headphones, and RESULT. Pairing was quick and simple, worked perfectly.So, In ear sound for me, and the soundbar acoustically for my wife, independently controlled. Very good quality sound in the headphones and undetectable lag (latency).The audio lead with 3.5mm plugs both ends is a really helpful 1 metre or so long, permitting the Trond to be placed with a clear aim to the listeners. Range was fantastic, right through the wall and into the kitchen (so now it's me has to make the coffees). I am using battery power alone and charging independently from a usb socket in another room when required. Not checked duration yet, nor yet added a second pair of headphones.Added Comment on January 16th 2020. Sadly the Trond started to misbehave recently and has now given up altogether despite my best efforts.Trond have now kindly promised me a replacement under warranty. We shall see (and report further).Added 22nd January 2020:Replacement arrived quickly. Worked well initially but problems again when re-pairing with Cambridge Audio earbuds after their use with a tablet. Trond were extremely helpful and attentive in attempting to resolve the problem. When it worked (eg with the AKG headphones) it was really good, just not with re-pairing with my Earbuds. I have given up now and purchased a different brand which seems fine.

Wanted a good Bluetooth transmitter/receiver, and after reading many reviews decided on this trond device. I wanted to use it on my hifi which worked well with my smart phone as long as I stayed within ten foot and kept the phone pointed at the hifi. I also tried my laptop within ten feet which worked after a while but kept dropping out, same with my wired headphones paired ok but as soon as I moved dropped out. So I decided to return them which Amazon made very easy to do and have not purchased another T/R unit as of yet. UPDATE...Have been using a replacement DUO II unit now for 3 weeks and so far has been much, much better and am very happy to keep on using it on my hi-fi. The music I can now play from my laptop & phone is predominantly mp3's, but sound very good played through the DUO II & my Nad amp & Eltax floorstanders. Bluetooth headphones work well too, so am now well pleased that I have the Trond unit on my system.
