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;DR If 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.

Are these worth $500 is probably what you’re looking at the reviews for. If you’re an audiophile, then absolutely they are. That being said, there are better options out there depending on what you need the most. Are these as good as my HD800S on a full audio stack? Definitely not, but they are way under that price point and power capability. They are still leagues above the AirPod Max, Bose, or Sony over the ear headphones as far as audio quality. But those other brands do better ANC, if that is what’s most important to you. Pros: - absolutely the best audio quality I’ve heard in wireless headphones. No comparisons. - ability to be fully wireless, lossless with the USB-C dongle (that does work on phones and Spotify btw!), wired with USB-C, or wired with regular analog cable. That’s a lot of options! - very comfortable, even on larger ears, I do wish the earcups were a bit larger but they’re still very comfy - awesome battery life. By far the best in wireless headphones -comes with a nice hard case that has room for everything it comes with - looks good - multipoint connectivity, so I can be connected to my laptop at work and my phone at the same time - app is good and actually works well Cons: - earcups could be a bit bigger, but they’re still comfy even on my ears, whereas the AirPod max hurt my ears after a short time - Bass is not overpowering. Which is a good thing for audiophiles, but a lot of people want super bass heavy headphones and these are not going to be for them. - ANC is not as good as Bose or AirPod max. If you NEED the best ANC, these are not for you. Either/Or - $500 is a lot to some people, but to audiophiles it’s a good price point for all that they offer - all plastic build can be a negative to some people. But it is sturdily built and Sennheiser is known for quality products. No doubts this will last. All in all, I love these headphones and will be using them almost every day. Again, these are not for everyone. But for audiophiles who want a great set for work or light travel, then these will be great.

Great sounding headphones; comfortable, customizable sound, long battery life, parametric equalizer. Noise cancellation fine for me. I like the hand genstures for the headphone as well. Multiple connection options. I use an iphone so the BTD 700 is great for me. Sennheiser helped me connect the BTD 700 to my headphones. Following is text from that ticket if you are having issues as I did. It's simple once you know and probably in the instructions, but , oh well. Try reinserting the BTD 700 into the device you want to use and then press and hold the pairing button on the BTD 700 until the LED flashed white and red. Then on the HDB 630 headphones press the power button in (8-12 sec) until the LEDs flash white and move in rapid sequence. When the LEDs on the BTD 700 stop flashing red and white and turns solid white the headphones are now connected. Make sure that High Resolution mode has been active in the Smart Control app and then play an audio file and the LED on the BTD 700 will turn pink indicating the BTD 700 is in aptX adaptive mode. You can also check in the Smart Control app under device management if the headphones are connected to the BTD 700 or the devices Bluetooth.
