The Sennheiser BTD 700 Bluetooth USB Dongle (Model: 700434) is a premium, compact audio transmitter designed to bypass your computer or mobile device's basic internal Bluetooth chip. It replaces it with a dedicated, high-performance Bluetooth 5.4 audio pipeline optimized for audiophile-grade codecs, lag-free gaming, and clear voice calls.

The core unit features a native USB-C male connector, making it directly compatible with modern smartphones, tablets, and laptops. It also includes a matching, precision-milled USB-C to USB-A adapter in the box, ensuring it can easily plug into older legacy desktop workstations and gaming consoles.

Core Performance Features

  • Audiophile Codec Suite: Most built-in computer Bluetooth chips compress audio using standard SBC or AAC. The BTD 700 introduces full support for Qualcomm’s premium aptX™ Adaptive (up to 24-bit / 96 kHz) and aptX™ Lossless codecs. When paired with high-end wireless headphones (like the Sennheiser Momentum series), it delivers bit-for-bit, studio-grade wireless sound.

  • 30ms Game Mode Latency: Standard Bluetooth introduces a noticeable audio delay ($\approx 150\text{ ms}$ to $250\text{ ms}$), causing gunshots or lip-sync to lag behind the screen. Tripple-pressing the dongle's single hardware button activates an ultra-low latency Game Mode, dropping delay down to a virtually imperceptible 30 ms on supported LC3 or aptX low-latency headphones.

  • Auracast™ Broadcast Multi-Streaming: Leveraging Bluetooth 5.4 architecture, the BTD 700 supports Auracast™. This allows you to broadcast a single audio source wirelessly to multiple pairs of Auracast-enabled headphones or speakers simultaneously—perfect for co-op gaming or sharing a movie on a flight.

  • True Hardware Plug-and-Play: The BTD 700 acts as a class-compliant external USB sound card. This means it handles all the Bluetooth pairing internally. Once you pair your headphones to the dongle once, you can unplug the dongle from your PC and slide it into a Mac, a PlayStation, or an iPad—and your headphones will stay instantly connected without going through the host device's settings menu.

Hardware LED Color Decoder Guide

The small status LED on the chassis shifts colors to give you instant confirmation of the codec your headphones are utilizing:

  • 🔵 Solid Blue: Connected via next-gen LC3 codec.

  • 🟣 Solid Purple: Connected via premium aptX™ Lossless (Bit-exact CD quality).

  • 🌸 Solid Pink: Connected via aptX™ Adaptive or aptX™ Classic.

  • ⚪ Solid White: Connected via basic legacy SBC compression.

  • 🟢 Solid Green: Gaming Mode is engaged (Low-latency prioritized).

  • 🟡 Solid Amber: Auracast™ Broadcasting Mode is active.

Critical Operational Advice

⚠️ The Codec Limitation Disclaimer: The BTD 700 acts as a bridge. While it is highly capable, it cannot force high-definition codecs out of headphones that do not physically possess the matching hardware decoders. For example, if you pair the BTD 700 with Apple AirPods (which only support AAC and SBC), the dongle will fall back to its high-quality SBC stream. To unlock aptX Lossless or aptX Adaptive, your headphones must natively support those Qualcomm architectures.

Morrison Finishing With Style!
Format: Hardcover
The exciting conclusion to Morrison's fantastic, fascinating, and F***ing awesome Batman and Robin run. Bringing together all of the pieces of his past stories to a head and blowing it all up in your face! Not only is the book amazing in the way it delivers a great pay off to a satisfying story it also offers an amazing ride on the way there. On top of all that there is some fantastic behind the scenes stuff in the deluxe edition that offers some in site into Grant Morrison's creative process, and the execution of ideas + this book has some great joker moments and also sets up Batman Inc with the conclusion of his Batman and robin story, along with the nice inclusion of "Batman the return" a nice one shot that sets things up for the future. All in all well worth the wait, and is a must have for anyone following Morrison's run on Batman.

Batman and Robin Will Never Die!!!!!!
Format: Hardcover
If you read Batman R.I.P. you saw those words shouted from the Dark Knight himself. This is the third volume of the popular Grant Morrison series Batman and Robin. This is also the conclusion of Grant's run on the book as well. We see a number of story lines finally reach their end. First thing first. I would recommend strongly that you purchase the first two volumes of this book. Just to give you a quick refresh this is not the Batman and Robin you are expecting. Richard Grayson is under the cowl, finally stepping in to the boots of his mentor. (Bruce was apparently murder by by Darkseid in Final Crisis.) The young lad who has taken the role of Robin is Damian Wayne. He is the son of Bruce Wayne and Talia al Ghul (daughter of Batman's nemesis Ra's al Ghul) . Let me say that this isn't your father's Batman and Robin. Well now that I think about it this isn't even my Batman and Robin. This is a Dynamic Duo for a new generation. Anyone who is familar with Dick Grayson either as Robin or Nightwing knows he is different from Batman. He is not the gloomy, dark and brooding character that Bruce is. Right away you will notice his Batman is different from his predecessor . (Heck, even Gordon and The Joker can tell). Dick's Batman may not be as dark as Bruce but he is not happy go lucky either. He has no problem opening a can of kick butt whenever it is needed. As for Damian this is a very different Robin as well. Robin was always light to Batman's darkness. The kid who says the one liners while Batman knock his foe unconscious. That is not the case here. Damian is dark, violent and a little of a brat most of time. Then again he was raised and trained by "The League of Assassins" since birth. I seriously doubt he has had the normal childhood others characters who wore the Robin mask did. Damian has no problem dishing out the pain either. Sometimes though he tends to dish out too much. In the past we seen him leave his opponents temporary cripple and with a concussion. This is the twist that I love about this book. The roles have been reversed. Batman is the lighter character and Robin is the dark one. What I also love about this book is we see the guy (Dick) who defined the sidekick role takes on a sidekick. Which is why we probably we see a lighter Batman. Dick is being the Batman he wanted. Bruce and Dick even though they were the original "Dynamic Duo" and define the hero sidekick role they still had their problems. It's great to see Dick become a father/big brother figure to Damian even if he is reluctant to it. This relationship is one of the best I have seen in comics for a long time. Now on to the story. As I said before the story "Batman must Die" brings to a close to Grants run on the book. I will not spoil anything but I will say it does not disappoint. We see Batman and Robin face what seems like impossible odds. A city in chaos and worst of all the Joker is in the middle. I will say one thing I love Grant's interpretation of the Joker and again like in "Batman R.I.P." he steals the show. I won't spoil too much but the Robin and Joker confrontation is great. (What happens when the Robin has the crowbar?) We also see you know who makes his return to Gotham as well. The big climatic fight scene is awesome. You see how much of a team that the current versions Batman and Robin have become. Speaking of which that is one of the biggest highlights in this book. We finally see these characters grow in to the new roles they have taken. When we first met Damian he was a brat who would not think twice about decapitating a criminal. I love watching him practicing restraint. This was the same character long ago who felt enemies should be dealt with no mercy. Now he is showing mercy. (Well some what) Despite what Damian has said he actually wants to change and be the hero that Dick and others believe he can be. I know some people might not like Damian because he is a brat and really obnoxious at times but I actually like him a lot. Damian is different from all the other Robins. Bruce trained Dick, Jason, Tim and even Stephanie the skills to be Robin and fight crime along side of him. Damian was thought to fight by assassins from birth. He has always had the skills. His path on being Robin is different than the others. He is being trained to be a hero. We finally see the hero he can be in this volume. In the first volume we saw Dick screaming to Damian about fighting as a team and working together. You almost had to wonder will this partnership even last? In this volume we actually see this Duo become Dynamic. We see Dick and Damian work as a team. We see Damian actually following orders. We actually see Dick and Damian become Batman and Robin. I didn't want to spoil much in my review because I didn't want to ruin a great story for any first time readers. Those who have already read this story know how it ends and where Grant will be taking the Batman Franchise in the future. I know sometimes Grant can go overboard and may lose many readers in a way too complex story but that is not the case here. I really hope Grant writes these characters again. Honestly its been a long time since I enjoyed a Batman book like this. I would recommend this book to any DC or Batman fan.

The end to one of the most epic runs on ANY superhero character
Format: Hardcover
Way back when Grant Morrison first took over writing on Batman, you could begin to sense the epic storytelling approach he was going to have on this book. And boy did he ever. From way back then with introduction of Damian, to Bruce Wayne being stuck in time, a new dynamic duo in Dick Grayson as Batman and Damian as the new Robin, every area has been fun to read. This volume and The Return of Bruce Wayne (which should be read injunction with this book) mark a great exclamation point for Grant's run on these character. Yes I know, we now have Batman Incorporated. But as of this writing, Batman INC has been put on hiatus due to the New 52 being implemented at DC Comics. While difficult to follow without a flow chart, this book really culminated the past almost three years of stories that Grant has been building up. And all is done with such drama and action, your fingers can't wait to turn the page!

The New Era of Batman Begins NOW
Format: Hardcover
I just finished reading Batman and Robin: Batman and Robin Must Die- the deluxe edition by Grant Morrison. This book, collecting issues 13-16 of the series and the special Batman: The Return, is so good it almost makes up for the goofball s pectacle of Bruce Wayne dying and hurtling through time to fight sentient organic robots or something. I still don't get what the f*** was going on there. Not enough acid in the world... The entire city of Gotham made fiending addicts by a new airborne virus, the new Batman and Robin of Dick Grayson and Damien Wayne are overwhelmed by the scope of the problem. Throw in an allegedly reformed Joker masquerading as a detective, and a morbidly obese psychopath in a pig mask squealing with delight at his own torture and you have a dark return to form for the Bat-books which have been marred in self-indulgent existential nonsense for far too long. The art is lush and cinematic, each panel more gorgeous than the last. The highlight of the issue for any long-term Bat fan HAS to be the scene with the latest incantation of Robin locked in an interrogation room with the Joker, beating him within an inch of his life with a crowbar. Both an allusion to the Joker's murder of Jason Todd from back in the 80's and the classic interrogation scene from The Dark Knight, this entire scene hums with the fierce energy of live wires. Then Batman (Bruce Wayne... the "real" Batman) shows up and takes this series in an entirely new direction than has ever been attempted before. This isn't just some comic book, it is pop art of the finest caliber. Make sure to purchase the deluxe edition for delicious insights into the decisions made regarding characters and plots points, selections which were anything but arbitrary. Grade: A+

Fantastic End to the Final Crisis Arc with Grant Morrison
Format: Paperback
Some of Morrison's best work, bar none. While The Return of Bruce Wayne in my opinion is the best of the Batman and Robin Volume 1-3 and Return of Bruce Wayne post-Final Crisis arc, this is also an excellent read / end to the Dick and Damian trilogy. The artwork is varied, eerie, phenomenal, though I recognize it is a love-it-or-hate-it style for some. Overall, I highly recommend this series, and this volume in particular is electrifying (ha!)
