Sounds good, just cant stop the smart pause
Annoying smart pause and control app that does not allow me to disable
Customer review from Sennheiser
Beautiful Sound Quality
I received this product free from Influenster and Sennheiser for an honest review. The sound quality is excellent and for the price I’d expect this. I like that the music is very clear and you can hear every word. And they’re comfortable to wear but if you’re wearing them for awhile they do feel a bit bulky. The App is a great addition and is easy to navigate. And the headphones come with a nice case too. They’re a bit pricey but for the sound quality if it’s in your budget I’d have to recommend these.

Good but room for sound improvement.
Product is good, but sound could be better. There is no distortion however some tones do not sound very polished.

Customer review from Sennheiser
Impressive headphones. A revelation for those crav
I’m about to review one of the most anticipated products of the year. These are my thoughts of the incredible Sennheiser HDB 630 Hi-Res Wireless Headphones. The Sennheiser HDB 630 marks the first wireless entry in Sennheiser's legendary HD 600-series lineage, blending audiophile-grade tuning with modern wireless conveniences. These just came out, and after testing these thoroughly, I believe that these closed-back over-ear headphones are meant for discerning listeners like me, you know those who want reference-quality sound on the go, without compromising on fidelity. These headphones build on the chassis of the popular Momentum 4 but feature a customized acoustic system for a more neutral, analytical profile. The key features of the HBD630 are: 42mm in-house dynamic transducers (made in Ireland) for hi-res audio support up to 24-bit/96kHz. Bluetooth 5.2 with codecs including SBC, AAC, aptX, aptX HD, and aptX Adaptive. Included BTD 700 USB-C Bluetooth dongle for hi-res transmission from any compatible device (even iPhones). Adaptive Noise Cancellation (ANC), Transparency mode, and voice call mics. Sennheiser Smart Control Plus app with full parametric EQ, crossfeed, preset sharing, and firmware updates. They give you up to 60 hours battery life (with ANC on), with quick charge (7 hours from 10 minutes). These come with wired options: USB-C digital (lossless) or 3.5mm analog. The design is comfortable and familiar, They are lightweight with generous protein leatherette padding, low clamping force, and a foldable structure that fits neatly into the included hard travel case. The touch controls on the earcups handle playback, volume, and calls intuitively. In terms of sound performance; I would say that out of the box, the HDB 630 delivers a strikingly neutral, reference-tuned signature: lifelike mids that make vocals feel intimate and present, stunning micro-detail retrieval, and a wide, natural soundstage unusual for closed-back wireless cans. Bass is controlled and extended without boominess, highs are smooth and airy without harshness (true to Sennheiser's audiophile heritage). My favorite things about these headphones are: Exceptional detail, neutrality, and resolution. The fact that they have versatile connectivity with the game-changing BTD 700 dongle for true hi-res on any source. The advanced app features like parametric EQ and crossfeed for critical listening. They also offer outstanding comfort and marathon battery life. So, I’m impressed. These Sennheiser HDB 630 headphones truly set a new benchmark for wireless audiophile headphones in 2025. I think this is revelation for those craving HD-series neutrality without wires. They are detailed, dynamic, and customizable in ways that make competitors feel generic. If you're an audiophile tired of compromising on the go, these are highly recommended.

Built for Real Listening, Built to Last!
I’ve used a lot of headphones over the years, and the Sennheiser HDB 630 immediately feels like it’s made for people who actually care about sound, not just background noise. Right from the packaging, you get a premium first impression. Everything is clean, well organized, and intentional. No wasted space, no cheap inserts. The carrying case alone stands out. It feels solid and well made, not flimsy, and it’s been perfect for throwing into a bag since we’re always on the move. The headphones themselves feel durable without being heavy. Hinges are tight, adjustments are smooth, and nothing feels fragile. Setup was easy. Pairing wirelessly took seconds, and connecting through the app was seamless. No random disconnects, no troubleshooting headaches. The app is intuitive even if you’re not an audio nerd, but it gives you the option to really dial things in if you want. The parametric EQ is a standout. Once we customized the sound, we started hearing small details in songs we’ve listened to for years. Subtle background instruments, layered vocals, and textures that other headphones usually miss came through clearly. Sound quality is where these truly shine. The tuning feels natural and balanced. Vocals sound lifelike, mids are clean, and the soundstage is wide and open. Bass is present and controlled, not overpowering. Noise cancellation is strong but smart. It blocks distractions without killing the character of the music. Transparency mode works instantly when you need to stay aware, which is especially useful while traveling or moving through busy spaces. Comfort was a pleasant surprise. I’ve got a bigger head and usually feel pressure after a while, but these adjust easily and stay comfortable even during long listening sessions. At the same time, my wife can borrow them without any issue at all, which says a lot about how well designed the fit is. One pair works for both of us without constantly readjusting. Battery life is honestly impressive. I stopped thinking about charging them, which is exactly how it should be. They easily last through long workdays, travel days, and busy holiday stretches. Fast charging is a lifesaver when you forget to plug them in. Usability is where everything comes together. These are great for travel, working from home, late night listening, or tuning out the noise during hectic days. They don’t demand attention, they just work when you need them. As for the price, yes, it’s on the splurge side. No way around that. But after using them, it makes sense. The sound quality, comfort, battery life, adjustability, and build all add up. Worth it enough that my wife is already asking when I’m buying her a pair too. The best thing about the Sennheiser HDB 630 is the balance. Premium sound without complexity, comfort without compromise, and features that actually improve everyday life. Put them on, press play, and everything else fades out.

Very comfy and with lots of features!
My experience with these HBD 630 headphones are positive. They are ready to go right out of the box. They fit my head perfectly and the cushion on the ears are wonderful. The quality craftsmanship of these are also top notch. I wished they would get a little more loud though as I found myself having the volume on max to have it at an acceptable volume. The noise cancellation is acceptable but not the best. An audiophile person would love the control of the music but hip hop and rap don’t have the volume nor bass like I’m wanting. I can still recommend them to everyone.

You have not heard music until you try these
The HDB 630 stands out as a premium wireless headphone that successfully bridges the gap between audiophile-grade sound and everyday convenience. The setup takes less than two minutes from the time you open the box and download the app. From the moment you put them on, the level of detail is immediately noticeable. Clarity and resolution are exceptional, with excellent instrument separation that creates a surprisingly spacious soundstage for a closed-back design. Music feels open and well layered, allowing individual elements to shine without sounding congested. The tuning is impressively balanced. Mids are neutral and natural, making vocals and instruments sound accurate and lifelike. The treble is refined and detailed without becoming sharp or fatiguing, while the bass is tight, controlled, and textured rather than overly boosted. This results in a studio-like presentation that will appeal to listeners who value accuracy and precision over exaggerated low end. One of the HDB 630’s biggest strengths is customization. The companion app includes a powerful onboard parametric EQ, giving users the ability to fine-tune the sound to their exact preferences—an uncommon and welcome feature in wireless headphones. When paired with the included BTD 700 USB-C dongle, performance reaches another level, unlocking high-resolution audio up to 24-bit/96kHz and noticeably improving overall sound quality and stability. Active noise cancellation is highly effective, making these headphones suitable for travel and busy environments, while transparency mode performs well, even if it doesn’t quite match Apple’s best implementations. Battery life is excellent, offering up to 60 hours of playback, putting it on par with top competitors like the Momentum 4. Overall, the HDB 630 is an outstanding wireless headphone that I highly recommend. It’s an ideal choice for audiophiles and discerning listeners who want superior sound quality, advanced features, and deep customization—especially when used with the USB-C dongle for the best possible experience.

Headphone
I like these headphones because they're lightweight and connect quickly to my phone. They also cover the ears and block out all outside noise. They're easy to connect, and the battery lasts a long time. They look stylish too and perfect size.
