Review: Excellent AptX LL Bluetooth Transmitter/Receiver plus outstanding customer service - There appears to be a lot of confusion about the various Bluetooth transmitter/receiver products and what they can and cannot do, and what is required to get the benefits of advances in Bluetooth technology. To clarify, there are currently three ‘flavors’ of music quality audio Bluetooth- A2DP, AptX and AptX LL. A2DP is standard Bluetooth that most cell phones, computers, wireless headphones and speakers use. It is serviceable with decent audio quality but up to ½ second of delay. When just listening to music, the delay doesn’t matter, but for watching TV it can be annoying, leading to a batter hitting a ball and the sound coming a beat later, or messing the sync of lips with the words they’re saying. AptX has been around for a while as a higher quality version of Bluetooth audio, with better sound quality and less delay, but relatively few devices support it and it still has a delay of roughly 1-2 tenths of a second. Better than A2DP, and good enough for people who aren’t as sensitive to the delay. But obvious and annoying when the TV sound is on (for people in the room), while someone is listening through wireless headphones. So the AptX people developed AptX LL, standing for ‘Low Latency’, a fancy term for low delay. AptX LL delay can be as low as 40 milliseconds (less than half of a tenth of a second), and for TV watching, is almost undetectable. In order to benefit from AptX LL however, you need a source that is transmitting it and a headphone or speaker that is receiving and reproducing it. This is where I think a lot of negative reviews are coming from- if you don’t have AptX LL at both ends, you won’t get any benefit. Since there are only a handful of AptX LL headphones, and no TV or hifi manufacturers have adopted it yet, miniature devices like the DUO S are designed to let the vast majority of existing audio devices take advantage of this technology. The Trond Duo S provides the most advanced Bluetooth audio experience currently available, and I am very happy with its performance. I bought it specifically to obtain satisfactory wireless headphone listening to my Sony XBR TV. When connected to a continuous source of power via the microsd port, it pairs almost instantly when I turn my headphones on (note many TV’s kill the power to their USB ports when they are turned off, and the Trond will shut off after some time to save the battery, and then need to be turned back on and re-paired when the TV is turned back on, so I would recommend using an old phone charger to power it). I’m using the Avantree Audition Pro, one of the only headphones on the market with AptX LL built in, and the sound is excellent, with negligible delay. The DUO S can also act as a receiver, to turn any pair of headphones with an ⅛” jack into AptX LL wireless headphones, but of course you need two of the DUO’s, one transmitting from the TV or other device and one connected to the headphones. Finally, I must comment on Trond customer service. This has been by far the most responsive company I’ve done business with in the internet age. We’re talking a $40 device from China. I was not expecting much when I emailed them a question. And yet I have experienced a level of communication that would make Apple envious. My emails were responded to promptly, in detail, by individuals with excellent spelling and grammar who clearly want my experience to be as positive as possible. I originally had some issues with getting the LL version of AptX working with my Avantree Audition Pro’s, and instead of blaming the other company, Trond bent over backwards to get to the bottom of the issue and offer solutions. So 5 stars for Trond customer service as well as the DUO S.
Review: After 1.5 years it still brings excellent sound ... - I have one hooked up to as a transmitter near my PC & projector, and one 25 feet away as a receiver near my Audio Receiver. My audio receiver is current, is bluetooth enabled, and is a high end system, but this product responds better. The sound is as beautiful as if it is hard-wired (still). I do not use the battery life for my Audio Receiver setup. I have, but prefer to keep it continuously powered-in so I do no need to deal with the inconvenience of re-charging or swapping for a new pair, then pairing again. The two send / receive gadgets have been paired all this time, fully charged and never failed. Both are always stationary. If I power down my projector, Audio Receiver, PC, TV signal source, etc., I leave this device powered-in and paired 100% of the time. This device has saved me a huge amount of time and effort avoiding the hard-wiring of speaker wire. If there is any delay of sound, I have never noticed it. If that happens I am confident it is a broadcast or recording issue - it has never been the fault of this device. I don't know why I have never reviewed this before - I cannot say enough positive things about the quality and simplicity of use. I have tried several other such gadgets and thought I would never find one like what I have now. I also have a pair of very high-end headphones, 3.5 sound jack only. I rigged a second sound outlet to broadcast sound and, with a couple of adapters, wirelessly receive that sound to my headphones (TV watching oriented, not an exercise compatible headset). My headset does not a volume control so the fact that this thing has a volume control is a real gift. The send / receive is a 2nd set of this device - which I do pair each time, and I do use the battery on the receive end. I have never looked up the projected battery life, as they have never died on me. So, I just recharge them when I am done. The sound is just as excellent. With this setup I use them to watch TV so as not to bug the neighbors at night and, therefore, there is not much moving around watching TV, Netflix or whatever. I do have to say that when I do move around, sometimes there is a bit of a temporary sound / bluetooth connection issue such that I have to watch what the receiving side of the gadget is doing. There seems to be either a line-of-sight or stationary requirement, or both. But considering all of the positives, I can live with that. I have not found anything better that allows me to use full quality of sound in my preferred systems, nor have I felt the need to look since I found this device. It is miles above any other device I have tried.

## Features

- APTX and APTX LOW LATENCY SUPPORTED. Powered by premium CSR8670 chipset, TROND BT-DUO S not only supports the latest Bluetooth V5.0, but also adds aptX and aptX Low Latency to both the TX and RX modes. With aptX, you can enjoy CD-quality sound wirelessly over Bluetooth connections with aptX-source devices like TV, phones or tablets; with aptX Low Latency, you can now watch video while listening to wireless audio in a synchronized fashion AND without any noticeable audio delay
- TX MODE: BLUETOOTH TRANSMITTER. By plugging TROND BT-DUO S to your non-Bluetooth audio sources (TV, iPod or Kindle e-Book reader), you can enjoy high quality music wirelessly or listen to late night shows without disturbing your family members on your Bluetooth headphones or speaker. Please also order TROND TD-BH01 Over-Ear Bluetooth V4.2 Headphones (ASIN: B075VLWPXF) for the best low latency performance
- RX MODE: BLUETOOTH RECEIVER w/ VOLUME CONTROL. TROND BT-DUO S can upgrade your old wired headphones (such as Bose QC25/QC15) or speakers into wireless with the support for aptX Low Latency. Its volume/track buttons allow you to play/pause music, turn volume up/down, and select track forward/backward. (NO hands-free calling due to lack of microphone; cannot be powered up automatically while you start the car ignition)
- PAIR WITH TWO and SMART CODEC INDICATOR. In TX mode, TROND BT-DUO S can pair to two Bluetooth Headphones, and streams audio to both simultaneously. However, in this application, the codec will be downgraded to from aptX Low Latency to SBC. It can also tell you which codec is in place by displaying different LED status. The blue LED blinks once every 10 seconds for SBC, blinks twice for aptX, and blinks three times for aptX Low Latency
- What You Get: TROND BT-DUO S 3.5mm Bluetooth V5.0 Transceiver with aptX Low Latency, 3.5mm male to 3.5mm male aluminum audio adapter, 3.5mm male to 3.5mm male audio cable (50cm extra-long), 3.5mm female to RCA male audio cable, USB to micro USB charging cable, user manual in English

## Questions & Answers

**Q: Is the trond bt-duo s otherwise identical to the trond bt-duo, except that it has a volume control in rx mode?**
A: Yes, that's the biggest difference. And TROND BT-DUO S has a slightly bigger battery of 200mAh, whereas BT-DUO has the 160mAh battery.Regards,TROND Customer Care

**Q: What is the range of this device, i.e., how far away can a transmitting or receiving device be from the adapter?**
A: This is actually a two fold answer. The quality of the headphones have an effect too. Between etrond's first transmitter and the new one, using Bluedio's UFO Pro's, their second adapter reaches at least 15' further using the same pair of headphones. They are both running bluetooth 4.1 and aptX. If you use and older version of bluetooth, your distance may be altered. I love the gained distance I get with etrond's new transmitter /receiver.

**Q: When does Trond anticipate incorporating the new Bluetooth V.5 into its devices?**
A: The SIG association is promoting the concept of Bluetooth V5.0 at this stage. However, it still take quite some time for manufacturers to design related products around the Bluetooth V5.0 chipset. Therefore we don't have any specific schedule for any Bluetooth V5.0 related products yet. Thank you for asking though.Regards,TROND Customer Care

**Q: is it compatible with jaybird X2 and the bluebird X?**
A: I would imagine it could. It hooked right up with my Bose QC30 set with no problem.

### ⭐⭐⭐⭐ Works Great...With One Exception
*by L***R on October 23, 2020*

This device is small and easy to operate and pair with other Bluetooth devices. I am using it on a projector as a Bluetooth transmitter for sound. When paired with my JBL Charge 3 it works great. There is no noticeable lag at all. However, when paired with my Denon home theater receiver, there is about a 4-5 second lag with the sound. Not exactly sure why this is, but I did buy this to use with my home theater system and it doesn't work with that. I'm keeping it though because until I can afford a descent wireless HDMI system, the sound from the Bluetooth speaker is far superior to that of the built in speakers in the projector.
