BTD 600 Bluetooth Audio Transmitter Dongle – aptX Adaptive & Low Latency, USB-A/USB-C for PC/Mac, Seamless Audio Sync,Plug & Play, Compatible With All Brands,Perfect Sync with Voice & Video

This is a good product and serves it's purpose well. Both momentum 4 headphones and tws4 connect seamlesslessly and connection quality is good. About sound quality, i dont notice much between aptx, aptx adaptive and aac anyways. For me sound personalization and equalizer settings and source plus music itself makes a quality difference than Aac, aptx and aptx adaptive. For eg, sometimes the output from my Samsung which has just aptx sounds better than the one from my moto which has aptx adaptive inbuilt. So i dont think you should buy this dongle just for increased music/sound quality. But you can buy it if at all you have connection issues between your laptop/pc and momentums.

It's plug and play and works really well on windows. I did notice an increase in audio quality as well.

This is a trouble free, no setup BT dongle. This supports SBC, AAC, Aptx, Aptx plus and Aptx Adaptive. There is a distinct improvement in sound quality as tested on my following Headphones / TWS: Audiotechnica ATHSQ1 (AAC) Astell & Kern UW100 MkII (Aptx HD) AKG 361BT (AAC) Yamaha YH -L700 (Aptx Adaptive) The difference in sound is distinct. It is worthy of the price. Music from the PC sounds similar to that from the android phone now unlike a step down as with the generic roadside ₹ 250 BT dongles. Range is also augmented.

Works flawlessly with my pair of Sennheiser Momentum 4 and transmits without any latency. Got it bundled with my headphones

I have a Bose QC Ultra pair of headphones, a Samsung Flip 6, a MacBook, and a Windows PC. My QC Ultra supports aptX Adaptive, but my Samsung phone supported only legacy aptX. I was using substandard SBC and AAC for these headphones over all my devices, and it was getting annoying. I already have a pair of Sony XM4 earphones and XM5 headphones, but LDAC is majorly supported over many devices nowadays. BTD-600 fixed so many things for me. The sound is very crisp. The low-end and high-end cutoffs are near perfect. Once you pair it with your headphones, it persists the connection for the next time. Apart from the minor inconvenience of plugging it into your device, this is an absolute delight to have. It's a high quality product. Just go for it.

I have been using this product for a while now and I honestly feel it has exceeded my expectations in many aspects. What impressed me most was the overall attention to detail and the finishing quality. Every feature seems to have been designed thoughtfully, keeping the end user’s comfort in mind. The interface is simple and easy to understand, so there is barely any learning curve even for someone who is not technically inclined. Performance has been smooth and reliable with no noticeable lag during operation. Build quality also feels durable and premium, which gives confidence that it will last long without problems. I also liked how all the essential functions are easily accessible without needing any extra setup. The delivery was on time, the packaging was secure, and installation was quick and convenient, making the entire experience hassle-free from start to finish. Overall, I am extremely satisfied and feel that the product offers great value for money. It provides exactly what it promises and even more in terms of user experience. I would definitely recommend it to anyone who is looking for a dependable and cost-effective option without compromising on features.

Setup is a little finiky, but once setup works like a charm.

Mainly for those who have Sennheiser Bluetooth earphones and headphones, though it might work with other brands BT headphones, I haven’t tried. I use with my MacBook (to connect to the Senn MTW4) and also works with iPhone (later models with USB charging port). Easy to install and use, it improves the signal to the earphones appreciably. I can now keep at half the volume as before to get the same sound level. The clarity and dynamics of the sound are substantially better as i can now listen via aptX HD which is probably twice as resolving than the AAC that Apple devices can transmit at best to the Senn BT earphones. It’s pricey, and there may be other cheaper models available from other brands, but this is worth the money if you are an audiophile and have a laptop/ phone without aptX or LDAC. Works without any glitch.
