Sennheiser 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.

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

Good product. Great sound quality. Good working. Price is little high.

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.

I’m a very satisfied buyer, this Sennheiser BTD 600 is fantastic. The connection is absolutely hassle-free with any Bluetooth audio device, and it stays rock solid every time. AptX sounds amazing on compatible headphones, and even SBC is surprisingly good. Best of all, I got it at a lower price than other alternatives while still getting solid premium quality. Highly recommend!

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

Great buy, Bluetooth latency is very low, sound quality is very good.

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.

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.

Conectividad de alta calidad con auriculares bluetooth de alta gama, hace de tarjeta de sonido independiente, en Windows tienes q cambiar la salida de audio 10/10

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 !

Ho preso questo dongle per sfruttare al meglio le mie cuffie Momentum 4 con il mio pc, perchè purtroppo causa di aggiornamenti Windows peggiorativi hanno reso il bluetooth inutilizzabile per le cuffie. Non si tratta di un problema hardware ma proprio di impostazioni software non modificabili che non permettono più switch comodi fra casse e cuffie, ma soprattutto impediscono l'utilizzo dell'ANC mentre precedentemente funzionava perfettamente. Con i dispositivi Apple tutto ciò non avviene e il suono si sente perfettamente. Questa situazione mi ha di fatto obbligato a scegliere fra questo dongle o l'utilizzo via cavo delle cuffie, ovviamente ho preferito la prima strada essendo esse stesse prese wireless apposta per questa caratteristica. L'abbinamento è immediato e semplicissimo, con questo modello specifico poi basta estrarle dalla custodia che si accendono ed abbinano immediatamente, con una comodità irrinunciabile. I codec audio sfruttati in questo modo sono i massimi e la qualità che viene riprodotta, se la sorgente sono brani flac o video con elevati standard, è eccellente. Precedentemente utilizzavo delle cuffie cablate al DAC audio e non ho percepito differenze, merito anche di questo prodotto che consente una comunicazione ottimale. Personalmente lo consiglio quasi come un acquisto obbligato per chi possiede delle cuffie wireless Sennheiser di alta qualità su un sistema windows, per non dover scendere a compromessi causa varie pecche software, visto anche il costo non elevato. Come si dice, fatto 30 fare 31 è azzeccato e sicuramente ripaga della piccola spesa.
