Very comfy and my small ears fit really well inside the ear muff bit. Pair easily with my bluetooth - no issues there. Only needed to do that one too as they are remembered. Good battery life as far as I can see and the sound quality is very good - I can't hear much else when they are on too which is a benefit. I've been using them to listen to some relaxation tracks as I fall asleep and they are plenty comfortable enough for me to fall asleep in them. They turn the power off after about an hour and a half which has startled me awake once or twice as it announces "power off" when it does that!
I like that their design is understated - I've been using Sennheiser products for years and I've found that they keep well. I'm very pleased with them. Their foldable design makes them slightly easier to keep and carry but they could have come with some kind of cloth bag.

I always like to comment few points when I review a headphones (Design, comfort, weight, battery, quality sound and cancellation noise) so I am starting now.
The first thing I would like to say is about the design, they looks good but nothing special. You can see the brand logo on each side. Big headphones foam...
Talking about comfort, that ones are not the most comfortable ones. My ears are a bit pressed by the foam because there is not enough space to keep them inside (I have small ears) so after certain time I have to take them off for a bit the let my ear take a rest...
Next point is the sound quality. The sound is ok but I don't think there is too much difference between that ones and others I have tried worth around £25... I think they should have a bit more volume and better bass... I repeat the sound is good but I will not pay £80...
It is lightweight. This is a point that I like. You can fold them to make it easy to store. Materials are good and even like that the weight is very correct. Not heavy at all.
You can use them though Bluetooth (very fast connection) and the battery life is long enough. I have charged for second time after 3 weeks. It depends how much you use them (it says enough for 30 hours).
And the last thing is the cancellation noise. When you wear them and you get music on It hard to hear anything around you but it is not perfect neither. Others I tried have better cancellation noise.
In general I say is good but I will not pay £80 for it. I would say £50-60 it is fair.
If you have any questions I will try to answer as soon I can. If this review is helpful for you please give me a like ????

I've always been a fan of Sennheiser headphones and this is no exception (I've also used Bose, Sony and a couple of others in the past, too).
- Firstly, it feels nice... not too heavy, looks sleek and well designed
- Long battery life, which is great (USB-C charger)
- Paired very easily to both my Kindle Fire and iPad (just hold the button down for a couple of seconds))
- Sound quality is really good... closed cup design means lower level of noise leakage which is good
- Clear bass and treble
- There is an app where you can adjust equaliser settings but I haven't had the chance to download it yes.
So overall a very, very good product... there were, however, a couple of points where I felt it missed out:
- No carry case; my other set of Sennheiser headphones came with a protective case, I'm surprised these didn't
- Bluetooth only (and perhaps USB-C wired connectivity). Unfortunately no other cable connectivity which I would have once missed but I guess most things nowadays have bluetooth)
- Buttons are a bit small. I would have liked to have slightly larger buttons on the headset
- Unable to clearly tell if the unit was switched on; there is a LED that flashes which switched on/off but it would have been nice to have a constantly on LED to show when powered on.
So... overall I thought this is a great product... highly recommended.

These are good quality headphones for the price. The value for money aspect has made me upgrade my star rating from four stars to five. These are at least as good as more expensive headphones that do slightly then this set such as active noise cancelling. They are far superior to the many other headsets from unknown firms that are roughly in the price range.
There were no connection problems and these are very comfortable and sturdy. The sound quality is very good and the handle a variety of music. The bass isn't particularly under or over powered.

Sennheiser devices always represent decent value; for the price the quality is great and these are no exception. I found the initial charge was quick and although I didn't quite get the 30 hours, my use was spaced over a couple of weeks so there will have been a little loss while they were idle.
The fit is comfortable, although the cups are perhaps just a little tight around the ear edges. The set is light, which compensates. In terms of sound, what you get is a well-balanced profile without any frequency really dominating. That makes it good for mixed use - voice, music and drama, say.
If you spend quite a bit more there are better options but at this price, this set is a winner.

I've had a number of Sennheisser phones over the years and they never disappoint and these are no exception, although they aren't perfect. You buy headphones for the sound, mostly (well I do) and these have a good sound with a decent, if not exceptional bass and treble, and which can be adjusted to suit your needs by means of an app - yes, yet another app to clog up your device. I found they were a little on the small side and it took a while to get comfortable with them, but they did seem to have good noise cancelling qualities, when used on an flight. One added feature for these is the voice assistant button for Siri and Google, which some will find useful, but no Alexa???
Anyway decent headphones for the money, from a reliable brand, just a couple of niggles to make it 4 stars

I've used Sennheisers before, though at the budget end and they were okay, but these are very good. Large ear covers so unless you've got elephant lugs they'll likely enclose the ear. Snug fit even on the smaller head. Nice and firm adjustment - no slipping and readjustment needed during use.
Sound quality is superior to other types I've used, including high-end Bose. It was a pleasant surprise to hear intricacies in familiar music which I had never previously detected. Nice and clear, very good balance of tones. Not too bassy and not tinny at all. Found them to be good for ambient, classical, pop and speech.
Wifi set up was very easy and there's a clear in-ear voice confirming connection. All adjusters and buttons are on the right ear and are easy to operate. Wifi range is far better than others I've tested. Indoors they pick up at about 20 feet from the device and only start to stutter in the one place in the house where, for unknown reasons, there's a permanent wifi dead zone.
Lightweight but not insubstantial. Comes with a c-usb.
I really like these headphones and am happy to recommend them.

My first pair of headphones I purchased was back in 1986 (Koss SST 7) these headphones gave a sound which I didn't believe until a year later I purchased my first pair of Sennheiser's and to this day I'm still using them.
These headphones HD35O BT wireless are superb especially for the price, after unboxing I could see and feel the quality and this is what I expect from Sennheiser, I've always purchased closed back headphones so I can shut away from the world and so I'm not annoying anyone sat next to me, the sound quality was crisp & clear especially as I downloaded the Sennheiser Smart Control App from Playstore so I could adjust the Bass and Treble.
The instructions weren't very clear and the writing very small so I got most information from YouTube on what the buttons were for, as for the Wireless I had had no problem connecting to my Samsung Note 10 which doesn't support a headphone socket so only Wireless for me at the moment, also it connected easily to my Sony Bravia TV but you must place the headphones next to the TV to connect because at first it wouldn't connect as I was literally 12ft away but wouldn't connect until I placed them next to the TV.
Pairing was easy and quick and you can skip songs by flicking the button/volume control/on/off switch, to pair these headphones you just keep the power button pressed down for 4 seconds and that's it, my only gripe is that even though I had the volume on max on my phone it just wasn't enough for me especially watching live concerts on YouTube I wanted to be actually in the audience but this doesn't happen because of low volume, for over 30 years I've used Sennheiser I've always connected via a 3.5 Jack plug in my phone or TV to increase volume so I'm thinking you lose something using Bluetooth.
Charging time is 2 hours and lasts for 30 hours.
What strikes me with Sennheiser that no matter how much money you spend you are always guaranteed a quality product and it's always been like this.

Sennheiser are quite well-reknowned for good quality audio kit, and these are no exception. Immediately out of the box, these take a bit of getting used-to in that they may feel a little small around your head at the outset, but they're adjustable. If you're a physically big person, however, you might still find your ears a little cramped inside the cups.
They paired up easily with my Razer 2 phone and share a USB-C charging connection; you get voice prompts for power on/off and pairing. The controls are a bit fiddly in that there's a few of them and they're quite small - power, a dedicated assistant button for Siri/Google, track skip and pause, volume, and call accept/reject. Sound quality and volume is also generally very good; a Sennheiser phone app will let you play with an equaliser to alter the sound even during playback. When in use, exterior sounds are inaudible at modest volumes even though they don't feature active noise-cancelling, so they're effective for planes & trains, or white noise while working; I've used them while vacuuming with great results.
The claimed battery life of 30 hours is excellent, with the bigger overall size of the headphones being usefully used to accommodate bigger batteries, although it does take 2 hours to recharge them fully, so some planning is required per day of use - you can use them while charging, however. They also don't come with any kind of carrying case or bag; they fold up and are probably more sturdy than they look, but I'd want some protection before dropping them in a bag (they're way too big to fit in most pockets). The only other complaint is that they're very understated to the point of being nondescript; too much bling isn't great either, but these just look like any other pair of matte-black headphones.
They do sound good, however, and value for money is similarly good. Notably, they're really good at blocking out the world in a similar way to much more expensive earphones I've used. What you lose in portability here you gain in comfort, quiet, and battery life.
