I mainly use these headphones for mixing and mastering (along with my Adam A5X monitors).

Comfort & Quality:

They are very comfortable to wear for long hours. The headband and the earpads are soft but still firm enough. The plastic used on the headphones looks and feels somewhat cheap, although I personally didn't have any issues with it so far. I've read comments online from people with broken headbands though. So, let's just say that I'd expect a higher quality feel on headphones that cost more than 300 euros.

Only (very minor) problem I've had with these headphones so far has been the cable connection on the headphone end getting loose. Maybe the connector wasn't properly in place to start with, cause this only happened to me two times in the first few days of use. I can't really comment more on the built quality / durability yet, since I've only owned them for a couple of months now.

Very happy with the monitoring experience. It's very easy to work for long hours with these headphones and the mixes translate very well. The soundstage is not so huge (compared to some AKG open-back models) but it is still there. I generally use them in combination with Sonarworks Reference, which gives them the boost they need in the low end (where they originally lack a bit of energy) and a minor correction in the high mid range, but really, the correction Sonarworks does on these is very minor, which shows that the headphones are quite flat to start with.

Oh and a very important note: I've read a million comments online about how it's super difficult to drive these headphones / one would need a powerful headphone amp and so on... Not really!! My Original RME Babyface (which is notorious for having not enough juice on the headphone output) can drive these headphones perfectly well, that is, to hearing-loss-inducing levels with great clarity.. but then again, loudness is very subjective, so you should try and see(hear) for yourselves.

All in all, I'd definitely recommend these headphones!!


An etermal sound
GeckoVST 08.11.2021
I purchased the Sennheiser HD650s as I was looking for a set of open backed headphones with a neutral frequency response. After reading a lot of reviews and opinions I was convinced that this was the best choice in this price range and I have not been disappointed.

The sound is beyond anything I have experienced before, even while being driven from my Mackie audio interface's output. While the impedance of these headphones is high (300 Ohm) they are still fairly easy to drive, so do not feel pressured into buying an amp before trying them on your current setup, even my laptops inbuilt sound card could drive them to a satisfactory volume.

These are the most comfortable headphones I've ever owned and I have regularly worn these through long production sessions and work days. After the first couple of weeks, the clamp force reduced and they are very secure and light.

To note: The first set I purchased had a defect in the cable connection and Thomann was quite responsive, despite the brexit shipping disruptions and replaced my set within a month. The version currently being sold is produced in Romania not Ireland doesn't come with a storage / carrying box.

To conclude, the clarity and reproduction of these headphones is fantastic, even after 15 years in production, they are still competitive, truly an eternal sound!

I was having a bit of a nightmare finding headphones I could afford that were flat/transparent enough to mix with. After doing a LOT of research and reading reviews and watching comparison videos and people's views, I bought some Beyerdynamic DT990s. However, whilst people LOVED them, I found the 'smile' bass and treble too distracting, so did a load more research - till I found these Sennhiesers.

They were so much more expensive and so far out of my budget, that I was reluctant to risk it…but I di and I am so thrilled with them! The sound quality is amazing! I almost feel as though I am mixing through my speakers. I can trust the sound, it is very vibrant and not tiring - and work so well just straight out of the headphone socket too.... in fact, I prefer that to via a headphone amp (which makes it a little bassier - but still good).

I haven't used them yet for long periods of time, but I can feel they are a little tight on the head grip (width), hence one star off for comfort, but it's a small price to pay for such an amazing sound quality. As for build quality, they feel very solid, have a decent weight behind them and again, feel like you can trust them to perform for a long while! Thank you Thomann for the great price - I definitely couldn't have afforded them from anywhere else!


Good, not perfect

These headphones are really famous and a lot of people recommend them--that's why I bought them for mixing. I wouldn't say they are perfect, my expectations were higher, but still, I not regret buying them: nevertheless, it's a GOOD choice. I use them with my UAD Apollo Twin sound interface and everything works fine, I have enough of headroom.

+ clear and detailed sound
+ interchangeable cable
+ nice look

- seemed to me too bright - but it's good for finding sound artifacts
- not so comfortable, a bit tight - after an hour of using them I had a headache (hope some time needed for them to loose up)
- the cable is not coiled (I believe the majority of sound engineers prefer a coiled one, as I do)
