"It is probably one of the best sounding wireless headphone you can buy if the objective is audio first. It is relatively light and the clamping force is right.However, the app is far from being good in 2025 standard. It has all the feature you might ever need for audio, but basic touch customization is lacking. You can only use the default control or disable it. A basic feature to switch between normal, ANC, and transparent mode is not even an option at of writing.Connecting to the hi-res dongle is not intuitive even with the paper quick start guide. The quick start guide is definitely not tested by someone not in the team, as the BTD700 section is so bad that even after I successfully pair the headphone to the dongle, I am still confused on what it is trying to tell me. The video on Sennheiser's channel is much better. If you cannot think of a way to teach the user using only pictures, you can at least provide a QR code to your channel for the better illustrations.$500 headphone minus the cost of the adapter is $450, which is competitive with Sony's offering. If you're looking for the best sounding WIRELESS headphone around this price point, this is the one to go. However, the current UX is still a bit questionable for me to recommend it to the general users.Hopefully the app becomes much more UX friendly in the future, but as of now, this is only for you if you're an audio first person."

I come from a background of audio production and general audiophile interest. I've gone through a number of amps, DACs, and a fair variety of headphones/IEMs. I'm well acquainted with EQs, tuning, sound stage, types of drivers, and all the jazz that comes with it. I'm not necessarily obsessive, I just really like good and clean sound with a bit of customization. These are the most impressive headphones I've ever used. Let me tell you why:- Out of the box these have neutral tuning with a slight preference for Sennheiser's tuning where they excel in the mids. This is likely due to a built in DSP helping achieve this performance on closed back headphones.- Wireless with NO compromises. You have all the codecs are your disposal, and frankly it will be enough for most people. Fairly low latency (for Bluetooth that is) and decent bit rate. For those earnest in getting higher quality (including better than MP3 providers can give you) then the USB-C wireless dongle has you covered. It may not be playing true FLAC quality directly into your ears, mind you we're still entirely wireless here, but within the law of diminishing returns you will be VERY happy with that quality you can get out of these. Rest assured.- Support for aux, airplane adapter, USB (wired), USB wireless dongle, and many bluetooth codecs- Compatibility: works on all devices that support Bluetooth or USB-C from my testing. Steam Deck, Android, MacOS, Windows (including Equalizer APO), and Linux (with Easy Effects *chef kiss*). I haven't tried iOS, but it'll work there fine too.- Battery life. Superb. I can't kill this thing, and when the battery inevitably degrades over time it'll still be more than plenty.- Mobile app. Sennheiser withheld no expense. Let's cut straight to the chase: Parametric EQ, and you can share your settings with other people. Fully customizable, but they still offer Graphic EQ if you prefer that. There's even a simple "Bass boost" toggle if you can't be bothered to change the other settings. Only downside: you are limited to + or - 6db in either direction. So if you want to max out the sub-bass shelf then you'll have about 12db to work with (+6 on sub, -6 on everything else). You can combine this with software side EQ in addition to this if you wish, like EQ APO or Easy Effects as I mentioned before.- Controls (swipes and taps on right cup) are fully customizable.- Comfort. It's good, no complaints. I'll talk about clamp force later.- Carrying case. It has room for the headphones, the wires, and adapters, plus room for more. It's also a flat case so it's easy to slip in to a bag.- Sub bass rumble. You won't get this out of the box. You can get a small lift out of the box with the app. If you use other software you can get a great sub-bass rumble that are not muddy. Sennheiser has always done a good job with this. I also appreciate that their "Bass boost" toggle in the app does NOT equate to "louder low mids". Thank goodness for that. We don't play with v-shapes here.Now that I've sang praises for its strengths, here are things that range from "passable" to "okay"- ANC (you saw this coming). To be perfectly clear, it's good. Decent, even. But it's not at Sony's or Bose's levels. They excel in that industry. That said, these work passably and will enhance your music experience. It'll get you the most of the way there. If ANC is more important to you than sound presentation, you have options elsewhere.- Transparency mode. It's good. Not the best I've used, but it's fine.- Clamp force. Yeah, they are slightly on the tight side on my head. Did you know you can fix this without leaving a zero star rating? Yeah, literally just grab some books and stack them side by side slightly beyond the width of your head and put your headphone cups on either side. Go to bed. In the morning the clamp will have relaxed and your problem is solved. You could even use a pot. A tight clamp for one person is a weak clamp for another. So of course they err on the side of tight, and yes you can address it.- Cost. You see the price. It's clear you're paying for R&D more than anything else. This wasn't intended to be the value option.- Swipe controls (right cup only). They work but are a little finicky. Not my favorite to use.TL;DRIf you want the best sound you can possibly get in wireless over-ear closed back headphones, these are it. Senheisser has knocked it out of the park. Full stop.If you want the best sound there is but don't care about wireless or closed back, you have cheaper options that perform the same or better.If you don't care about the v-shape signatures you get from the competitors in this space, or if you want better ANC, you also have other options.jayendra ingale

The media could not be loaded. Sound quality of these is PERFECT. You can hear every single, smallest of sounds as if hearing the music live. The clarity is simply unrivaled. The soundstage is incredibly wide, somehow even wider than my open back sennheiser hd660s.Slightly heavier than typical wireless headphones, but overall very comfortable. There is no fatigue even after 3-4 hours. Build quality is excellent and earcups are very deep and supple.Connectivity is also excellent. It has bluetooth, 2.4ghz dongle, usb-c, 3.5mm, airplane connectors, everything included in the box.Absolute steal at $500.robert j boustany jr

Did a bit of research prior to purchase. There are quite a few cans in this price range, with this model being the most recommended over several well known names. They were recognized by my Pixel 10 XL Pro immediately and Bluetooth connected. Soundstage is perfect, bass is not over boosted, and treble is clear but not over bright or piercing. For some reason, the price on the other wireless Foca- brand more than doubled within a year. That made the HDB 630 choice easily the best value for the money. Head fit is not too tight. Noise cancellation is quite acceptable. Happy with my purchase.What Customers Talk About
