Sound is good but Generally these headphones fail. I have the wireless version with touch pad controls. The headphones have difficulty connecting to my phone, and difficulty staying connected. The touch pad control is ridiculous, painful, and completely unnecessary. I’m guessing that is was partially developed when released and quickly canned. Buttons would have done the job better. The buttons on the lead work well and feel nice, but these are meant to be wireless.
The ear pads are falling apart, fall off in my bag, and are difficult to get back on.
Battery life is good.
I got these to replace some sennhieser in ear headphones which cost $80 and were awesome. Expected great things for $400. Very disappointed. Usability is a big fail.

These headphones are good and have good sound quality but the cord could have been longer and you can only get a 1.2 meter cable which could have been longer and the adjust ability could have been tighter because they can slip if you have a smaller head.

Sound is great but the ear pads started falling off almost immediately and were a real pain to put back on. They have both now deteriorated and fallen to pieces after very little wear and the headphones are now effectively useless. I will not be buy a Sennheiser product again. Extremely disappointing.

Left in storage for a year without use in tropical Australia. After one hour long listening session, bits of black 'cloth' started cascading down on my work desk and the mesh underneath was revealed on both ear cups. Two days later one entire ear cup fell off and if you've tried to refit one of those, I can recommend some anger management counsellors. I bought them because in my 62 years I've yet to find any brand which can produce the sound quality that Sennheiser do for a comparable price point. These headphones were no exception - totally amazing. Replacement ear cups are $50 a pop and no way of knowing if they have changed their construction. Very disappointed.

We bought the iPhone version and they work fine with Android devices, however, the in-line buttons don't work properly. Don't buy if that will be a problem. Another caveat is that these ARE for larger heads; they side down my girlfriends head too easily and so aren't comfortable for her.

Sound quality, particularly base, is great. They work nicely with my PS4, too, although they don't come with a mic.

If you're big on base and have a bigger sizes head, go for it!

While these headphones are on the pricey side, the quality is very good and they are very comfortable when wearing. However, sometimes the ear pads fall off which can be annoying and the sound often turns off on either the right of left side. However the customer service from Sennheiser is very good and they will immediately send out another pair

Amazing headphones, long battery life at 25 hours and a sound that is addictive! I've barely had these headphones off since i bought them. Very comfortable on the ears as well.

These are not wireless nor do they have noise cancelling function, and the retail price is too high as other reviews have pointed out. However, if you put them on, you will like how comfortable they feel & they deliver decent sound. Thus if you can get them on discounted price, then you should probably consider giving them a chance; who knows, you may be pleasantly surprised.

Picked these up for a bit over $100 and I found it great value. Sound quality is very good and bass is solid and smooth as well. The ear-cup positioning makes a massive difference on these tho when it comes to bass. A bit difficult to explain but I found that sliding them on from the front rather than from the top helped to flatten out the ears and get those ear-cups on properly. Doing so while you are playing something quite bassy would probably help with the adjustment as well. I listen to trop house, mixes, rebassed and bass boosted stuff a fair bit (youtube is a good starting point if you want to try some out) and that's where these really do shine for mine compared to say the momentums.

It is very comfortable and provides a good quality sound. It becomes a good friend which accompanies with me. Personally, i think it is better than the smaller size of Sennheiser Urbanite as it is more suitable for us to wear. Well, it was a really good headphone production. I like it.

My husband purchased these for me for Christmas and I love them.
They are comfy to wear and easy to adjust for the perfect Fit.
Sound quality is great and are pretty good considering they aren't noise cancelling.
They are convenient to travel with as they fold down and come with a carry pouch.
Love the colour (purple).

Purchased with offer of EFTPOS card cashback. Sound is good and sits comfortably. Wire-free convenience is a blessing especially on the plane (adapter purchased separately). In case the batteries fail, they have included a (detachable) 3.5mm cord, which also has a locking mechanism to prevent accidental disconnection (good design). Only design flaw are the velour ear pads which can dislodge (happened whilst in protective felt bag) however it took only a few minutes (and much patience) to put them back on. Also whilst the headphones can fold up, there is no protective case included.

Went looking for some wireless headphones after my cats chewed through the cord of my beloved previous Sennheisers. Decided to stay loyal to the brand and these did not disappoint! Good sound quality, comfortable to wear, the battery lasts at least 12 hours per charge, and the bluetooth range is quite impressive (I can listen to things from different rooms sometimes!).
