BTD 600

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.

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.

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

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

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.

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.

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.

This thing works. Just go for it and you will not regret.

Unter Win11 klangen meine Sony 1000xm3 einfach mies. Irgendwas fehlte. Sehr ungewohnt, weil die Kopfhörer trotz Vor-Vor-Generation noch richtig super sind. An meinem Handy sind die klasse. Aber am PC echt mau. Nach ein bisschen googlen stieß ich auf den aptX codec, der wohl sonst unterstützt wurde, aber seit win11 eben nicht mehr. Viele nutzen den wohl gar nicht mehr. Diese Kopfhörer haben diesen Codec noch. Und der Sennheiser Stick bringt den mit. Also irgendwie logisch, dass man da mal ansetzen kann. Ausprobieren! Angeschlossen, sofort erkannt. Leuchtet weiß. Ganz ok. Schnell da. Keine Probleme. Ich kann also nicht sagen, dass ich Schwierigkeiten mit dem Verbinden hatte. Aber das Ding hat nicht Pink geleuchtet, was bedeutet, dass der Codec aktiv ist. Mit dem Handy verbunden, in die Sony App gegangen und in den Einstellungen auf "Priorität auf Klang" geschaltet. Das hat wohl nicht nur Einfluss auf die Verbindung zum Handy, denn siehe da: der Dongle leuchtet Pink. Und damit konnte ich alle "Soundverbesserungen" unter Windows und Spotify, die als Krücke dienten, deaktivieren, und habe eine deutlich besseres Ergebnis. Endlich klingt es nicht mehr nach Blechdose und irgendwie hohl oder entfernt. Auch sind die Kopfhörer deutlich lauter geworden. Der Kopfhörer verbindet sich sofort mit dem Dongle, wenn ich ihn wieder einschalte. NUR, muss ich in Windows den Audioausgang, unten links, manuell einstellen. Von Lautsprecher auf BTD600. Ja, das ging vorher vollautomatisch. Aber Windows erkennt den Dongle hier nicht automatisch als Ausgang sondern als eigenes Gerät. Bluetooth kann man unter Win11 dann auch ausschalten, weil der das nicht über den Dongle erkennt. Hat man einen zweiten "normalen" Dongle dran, dann wohl besser anlassen für die BT Umgebung. Bin damit sehr zufrieden, weil der Klang deutlich besser ist. Preis/Leistung ist ok, weil es einfach endlich funktioniert. Muss man halt wissen, weil man für ca. 1/3 des Preises einen BT Dongle bekommt. Also erstmal schauen, ob man diese Zusatzleistung benötigt. In meinem Fall hat aptX für einen echten Qualitätsanstieg gesorgt. Im "Normalbetrieb", wenn die LED weiß leuchtet, ist der Dongle stabil, aber eben auch nur ein gesonderter Audioausgang, den man dann wohl einstellen muss. Verbindung ist aber stabil und schnell.

I owned a Bluetooth headset from Sennheiser (Bt450) and with the smartphone are a joy. Because of silly restrictions i can't use my built in bluetooth to connect it with my work laptop. Such a shame that I couldn't enjoy all the cool stuff this headset can do because of the restrictions. I also owned a Bluetooth headset whose dongle was a danger to carry around because of its size and qualitywise less enjoyable than my bt450 "If I only had the dongle recognized as headset from Sennheiser i would make 3 devices in the house/office redundant" This tiny dongle does it. In a brilliant way. Is simpler than I thought could be, the pairing process is even more straightforward as it has a lovely button On Off in its head: minimalist and cool looking. Excellent sound transmission. Now i can be connected simultaneously with the phone and the work pc. Best money spent.

The sound was really good, setup was quick. Connection reliable. Worked for 9 months and is now broken. It just appears and disappears from USB every few minutes or so. Wish I could get a new one, not sure if I want to pay for it.

Works perfectly with my Sennheiser Momentum 3 & 4.

Après avoir bataillé avec le Bluetooth de mon pc portable qui coupait toutes les dix secondes j'ai découvert ce dongle et là j'ai franchi un univers, outre qu'il n'y a plus de coupures la qualité du son est excellente ! L'installation est simplissime et la connexion avec un lecteur Advance Paris Streamtubes a été immédiate ! Je recommande ce produit certes un peu plus cher mais le qualité est au rendez vous !
