TROND Bluetooth Transmitter Receiver for TV PC iPod, Digital Optical Input & 3.5mm Aux Port, 500mAh Battery Powered, Dual Link AptX Low Latency - Specially Designed for Pairing Two Devices

Back Story:I am a regular user of bluetooth streaming, almost every night I turn down the TV sound so as not to disturb the others. I use my bose wireless headphones to watch various shows. Initially I started out using a very cheap bluetooth transmitter from Radio Shack. It worked decent enough for a while, but then the problems started when my neighbors installed some bluetooth speakers in their garage. Their speaker always happen to stay in discoverable mode when not in use. This posed a real problem because my old transmitter had minimal controls and would pick up any and all discoverable speakers within range and pair with them and start to stream audio to them. I struggled with it a lot but to no avail. It caused a lot of unwanted disturbance to my neighbor and eventually they were very nice about it and the would unplug their speakers every night. For me, this was quite embarrassing.I tried other bluetooth devices I got from Fry's Electronics, but they also had the same problems.This got me quite frustrated and I went online to find the transmitter with the best ratings. Trond BT duo came up near the top.Main Review:I ordered the device from amazon. Packaging was easy to open, no frills cardboard box. Instruction manual was decent. It came with all the accessories needed to attach it to any audio source.It solved my neighbor problem in a big way because it has a dedicated button for pairing with a secondary speaker. It will pair with more speakers if and only if I instruct it to do so. As long as I stay away from this button, there's no chance of disturbance to others.It has the 3.5mm audio jack, but in addition, it also has the digital optical input, which meant I could stream way better quality sound than before. There's a dedicated physical switch for putting the device in TX or RX mode which is very pleasant. Also there's a micro-USB port for charging the battery in the device. I always keep it plugged in to USB and it sits inside my TV cabinet and never runs out or needs charging.Performance:The first thing I was amazed by is the superb sound quality, full stereo hi-fi sound. My bose headphones were capable of so much better sound and were not being used to their fullest potential until I started streaming audio through the Trond BT duo.Other noticeable performance aspects were that there was no lag (none that I could notice), between the picture on my TV and the audio that was streaming through my headphone. It was perfectly synced. I've noticed considerable lag with other streaming devices (it gets really disorienting), but no such issue with this device.The range of bluetooth radio was also way better than before. I could go quite far, even go upstairs and still not notice any static or drop in sound quality.Recently I ran into an issue where device became un-responsive and wouldn't pair and stream properly. I tried various troubleshooting steps, but nothing worked. So I sent an email to their customer support. I provided my Amazon order number (in case they try to hassle me about these things), and a brief description of the problem.I sent the note out at my 11 pm, not expecting a response until the following day or maybe several days out. They responded within 15 minutes; told me there was a hard-shutdown button I can press with a metal pin. They even provided a picture, where to find the button. I was really amazed with the level of customer care. The guy who helped me, his name was Bruce, was courteous in all his communications.Nowadays customer support for most companies have made an art out of trying to get out of helping customers, putting them through hurdles, wasting their time. With Trond I found the exact opposite, which was quite refreshing.In summary:Pros:- Excellent sound quality- Excellent range- No lag- Dedicated button for pairing additional speakers/headphones- Good battery life- Space-saving design and muted black color- Excellent customer supportCons:- None that I could think of.

**UPDATE: Today (03/21/18) I tried to find a phone number to call for support, but they do not have a phone number! I then visited their website: www.etrond.com only to find out nearly all their links are broken and don’t work. For ex: go to products page and try to click on any of the menus on left. This greatly concerns me that I am not dealing with a solid company that is going to stand by their products. I will give them some time to reply to my support email and update here.**ORIGINAL REVIEW:I bought this TROND Dual Bluetooth Transmitter for the explicit reason of watching movies with my wife after we put the kids down for bed. I wanted the days of super-low volume and captions on the screen to be gone. Turning up the volume and risking waking up the kids was not an option. That being said, we already had a Bluetooth headset that belonged to my daughter, it wasn’t AptX Low Latency or anything like that, just a basic SBC codec Bluetooth headset. For my second pair I ordered the TROND Bluetooth headset with AptX low latency codec to match this Bluetooth transmitter. The description of this transmitter says it will work with any Bluetooth headset ...and it does, just not at the same time. If I turn off my set it picks up my daughters set, and vise versa but it just won’t do both at the same time no matter which I pair first. I followed the instructions to pair two sets and everything went without a hitch, including the triple green flash. But still it was a no go. I have not had the time to call tech support during a reasonable hour yet - I will do that tomorrow and update this review if anything changes. I expected the signal to drop to the SBC codec for both headsets because of my daughters older unit but that wasn’t the case - I now got a feeling they both have to be of the same make and model to work together. I will say, when using just my TROND set I notice a real difference in the low latency - it’s great. Also the included accessories with this transmitter are superb quality. Those two things alone kept it at 4 stars even with my hiccups.
