Features:

  • Apt & apt Low Latency. Powered by premium CSR8670 chipset, TROND BT-DUO supports apt & apt Low Latency in both TX and RX mode. You can now watch movies while listening to wireless Audio in a synchronized fashion and without any noticeable Audio delay. In order to avoid the Audio lag, your Bluetooth headphones or speaker also need to support apt Low Latency. Please refer to your headphone or speaker Manufacturer and verify whether their devices could support apt Low Latency
  • TROND BT-DUO can transmit stereo Audio wirelessly from your non-Bluetooth Audio sources such as TV, MP3, CD player, PC or book Reader to your Bluetooth-enabled headphones, speaker or receiver. This way, you can enjoy high quality music wirelessly or listen to late night shows without disturbing your loved ones while they sleep. Please order TROND td-bh01 over-ear BT V4.2 headphones to use with this transmitter and to avoid the lip-sync issues
  • Due to apt Low Latency supported in the Rx mode, BT-DUO offers an economical solution by turning your old wired headphones or speakers into Bluetooth headphones or speakers with the feature of apt ll. Now, you can enjoyed-like Audio quality wirelessly on your home stereo or wired speaker. Please note that TROND BT-DUO doesn't have the built-in microphone, and hence doesn’t support phone calls
  • Dual stream & multi point. When used as a Bluetooth transmitter, TROND BT-DUO can be paired to two Bluetooth headphones or speakers, and streams audio to both of them simultaneously. Working as a Bluetooth receiver, it can still be paired to two of your smartphones or tablets, but the receiver can only receive the Audio from one of the two paired devices. Please note that the codec would be downgraded to SBC when pairing to two BT devices simultaneously

Works great, connects quickly

Got this to replace an old BluBridge receiver in my car so I can stream music from my phone to my ancient cassette-radio unit with one of those cassette adapters which you then plug into the Bluetooth receiver. If you have a cassette radio and no AUX input this is a great solution. This Trond unit connects very quickly and automatically. I just push and hold the power button briefly and I'm streaming music in my car in just a couple seconds. The old BluBridge I had before needed to be manually connected to my phone each time which was a pain. I chose this Trond unit as well for other features I may appreciate in the future. 1) It can be a receiver or transmitter 2) it supports "aptX Low Latency" which is useful if you want to use it as transmitter to watch TV with headphones and not have lip movement out of sync (make sure your headphones support this feature as well). Very happy with this unit.

I've tried close to 10 of these and this is the I'm sticking with...

I tried close to 10 of these bluetooth devices. Some of them were ok. Some were terrible. This one had a few peers in quality but not in size and price. This thing is tiny. I use it in my car. See pics attached. It's size is unobtrusive and hardly noticeable and works real well where I've mounted it. Which is right next to my aux input and cigarette lighter jack. I bought a short (6") USB 2.0 A Male to Micro B USB cable (https://smile.amazon.com/dp/B013G4EAEI). It comes with a similar length aux cable. And together it creates a nice little setup that no ones really notices. I mounted it so that you can somewhat see the single button on the device. That button lights blue/red when you put it into pairing mode (holding the button for about 5 seconds). That button is so flush with the device you really can't feel it or know when you are actually depressing it. So it's important to be able to see when the color changes to the blue/red almost purple color. That means it's ready to connect with your phone. And yes, you have to reconnect to it every time you get back in the car. Which is the only unfortunate "feature" about it. But I didn't find a single bluetooth device that would auto-reconnect after losing power in the car. Actually it doesn't even lose power because it stays connected to the cigarette lighter power. But the device turns itself off. So when I get back in the car I have to hold the hard-to-feel button for about 5-6 seconds and then my phone connects on its own. Unless someone else was last connected to the bluetooth device then sometimes I have to go into my bluetooth setting (I'm using an iPhone) and tell it to reconnect. But that is not often. And it doesn't have to stay connected to the power in the car but for me there is no sense to ever have it unconnected. So it just stays "charging" all of the time. Overall it's a nice little quality piece of tech. I chose it over a bunch or more expensive units (and some cheaper ones). Don't hesitate to buy it if you need simple and solid.

Works great

I am using this Bluetooth device with an LG TV and it works great. It did take me a couple of tries, so passing this along in case it's helpful to you. The audio menu on the LG 55EF9500 has several choices including Audio Out and Wired Headphones (see pic). I originally selected Audio Out because that's the port I am using for the Bluetooth transceiver. That didn't work. The headset would pair successfully but I couldn't hear anything. The right setting is actually Wired Headphones. Even better, I'm using the Internal TV Speaker + Wired Headphones. That way I can control the volume on the headset and TV speaker independently, and I don't have to review this menu every time I want to watch TV. If I want to use the headphones, all I have to do is press the button on the Bluetooth device to connect and I'm good to go.

Old iPod Shuffle - lives another day

Works great with old iPod Shuffle generation 2, wireless sport earbuds! There is no latency and it was super easy to sync, which surprised me. It is so light and small that I hardly noticed an additional piece of equipment during my run. I also paired it with my hybrid piano..hmm, latency was obvious, but it worked if you played a very slow piece! I am just happy that I could reuse my iPod Shuffle wit my wireless earbuds. .

Better than expected. Works good for have two headsets connected to one output.

Really had doubts about this as to trying to get it to work with two blue tooth headsets. Wife and I both go walking to workout music which goes by the beat. Both of us hear the same music from one phone with this transmitter and keeps us in sync without disturbing others since we usually Mall walk. Size is pretty small and fits in the phones holster pretty well. I could think of several other applications where this would be handy. Pairing has to follow the directions exactly and takes a few minutes, but not overly difficult. Maintains pairing good when restarting each time. If my wife has the need to sing along, at least were listening to the same song.

Compliments the Nintendo Switch perfectly!

I’ll keep the review short and sweet The device is the size of a narrow matchbox and holds a connection incredibly well, even better than my MacBook Pro which cuts out BT connection with every headphone I have. It’s fast to pair over both TX (transmit) and RX (receive) and has seemed to last the advertised 8 hours on battery. I have mine attached to a Nintendo Switch with a small Velcro strip and ultra short 3.5mm interconnect cable. Recommended!

;Works great for our American-style ballroom practices!

My wife and I bought two MPOW(Gen-2 Version) headsets and this "TROND® Bluetooth V4.1 Transmitter Receiver Audio Adapter with AptX", for ballroom dance practice,. We dance American-style so there is a lot of free-spinning and head-movement. I delayed this review until we could get several hours of experience with them. On a 40'x40' practice floor, the blue-tooth reception range stays solid across the whole floor with the Trond in one corner (well over 10m), when we leave it sitting stationary. We get skips (but no loss of beat) when the Trond/player is in my pocket but that seems to be from cable-movement at my player's audio-jack connection. RePairing this Trond with those two headsets still seems more art than science, but my best result seems when we power-up the two MPOW headsets first, and then the Trond. Still, I've always managed to get both headsets to pair, and then they stay linked and sync'ed. We have yet to try our setup in an practice-area where there are gobs of blue-tooth devices competing for bandwidth. I expect some issues, and particularly with greater distance and competing devices between the Trond and our headsets.

Setup is a bit unintuitive, but it works.

The product works perfectly, but Buetooth itself is a complicated, somewhat unreliable technology, like racing blind into a busy intersection with your eyes closed. For my setup, I wanted something I thought should be simple: an AppleTV 4 playing music through my Samsung TV and Onkyo receiver, with music coming out both the wired speakers in the playroom and a pair of Bose Soundlink Minis on the patio outside (wirelessly, via BlueTooth). For reasons too annoying to go into, my original plan just wouldn't work. AppleTV would output audio via HDMI or Bluetooth, but not both at the same time. My Samsung TV could take the audio in via HDMI and then output it via Bluetooth, but hijacked the audio from the HDMI in the process, leaving my 7.1 wired speakers completely silent. I came up with several potential alternatives involving an HDMI splitter and more cables, but I wasn't certain this would work either. Then I came across this product, which cost less than all the additional cables and the splitter would. So I gave it a try. I'm glad that I did. AppleTV still outputs audio via HDMI to the TV and stereo, and the TROND BT Transceiver broadcasts the same audio wirelessly via Bluetooth out the TV's headphone jack -- the classic "analog hole" solution! The combination works perfectly. Sure, there's a slight lag between the wired and wireless speakers, but you can't really hear the wired ones when in range to hear the wireless, and vice versa. Plus, in a noisy party situation, the effect was too slight to notice anyway. My one regret is that I had to actually read the directions. The setup process for pairing two Bluetooth speakers, even when two fo the exact same model, is not intuitive... but it works. Should of including a display on this transceiver (and consequently boosting its price), I can't see any way around this. Give it a chance and read the directions. It works.

I wanted a way to connect two Bluetooth headsets so my wife and I can watch the same movie while flying. The Trond unit arrived in good shape and connected to both headsets without issue (I did have to turn the Bluetooth setting off on our two iPhones first). I did have one small issue after one day that was easily remedied, thanks to a quick response from Trond technical support. The unit "froze" in the on position and would not turn off and would not connect to the headsets. I emailed Trond technical support and received an answer within a couple of hours with instructions to let the Trond unit battery run out and then recharge and all should be good. The tech described it as similar to a computer crashing. After the battery ran down and I recharged it everything worked great again! I didn't even need to re-pair with the two headsets. I will not hesitate in the future to buy anything Trond makes based on their great technical support!

Does everything it should do on the Nintendo Switch.

I purchased this as a stop-gap solution for my Nintendo Switch's lack of Bluetooth audio out (Seriously Nintendo?) It works fantastically and is at a lower price point compared to the Taotronics' 4.1 model, despite being the exact same item with a different printed name. I also picked up JDS Lab's "ULTRA SHORT 3.5MM INTERCONNECT CABLE" (currently not for sale on Amazon, use Google) to ensure that it sits beautifully flush behind my Switch, mounted by black 3M picture hanging strips. No discernible audio lag for me while playing Zelda BotW with AirPods. Edit: Forgot to mention that this device works well with AirPods pairing procedure. Once initially paired, the AirPods will automatically defer to the transmitter when you turn on the transmitter, even if it's currently connected to your phone. If you need to use your phone, simply turn off the transmitter and select the AirPods from your phone and it will switch over. Keep in mind that as long as the transmitter is left on, it will always hijack the AirPods from whatever device it's currently connected to.
