My first set of open headphones!

I am quite pleased with these. My only complaint is that they don't have an inline volume control. The blue marble design is old & cheesey looking. As others have said Sennheisers fit tight but gradually become more comfortable. They are designed for home use which is why I purchased them. I compared these to several other sets of open phones. First was the Sennheiser 650's. As many said, they seem to have a veil that darkens the sound somewhat. The 600's do not. A positive and a negative: These really make all the instruments , especially when listening to classical. Each instrument stands out. Sometimes I just have to refocus on the whole composition. It has been over 6 months since i purchased these headphones so all my mental notes have somewhat faded. Still love them.

So worth it

If you like music, especially instrumentals / vocals you will love these. If you have never had a solid pair of headphones, you will love these. I personally believe anyone who enjoys music, should have a pair of good headphones like these. I originally had a pair of vmoda mx-100 which are also pretty stellar, but the bass can be exhausting, and so can the heat buildup. I think of the hd600 like a classic timeless piece. not flashy but so solid everywhere to the point that it stands out. songs will sound different than you've heard them before. 2 things I don't love, the proprietary connectors to the headphone, and sometimes i notice the clamping strength on side of head, but definitely not a deal breaker.

Solid headphones

I got these headphones headphones two weeks ago and I can say they are easily my favorite headphones by far. I�ve never been an audiophile I�ve always gone with what�s comfortable Bose qc25s, Sony WH1000XM3, etc. I got my Sony�s and loved them for 5 months then got tinnitus long story short it made using the headphones awful and all closed back headphones seemed to make it worse. So after doing research I decided to get these so I can use headphones again and I love them more than my sonys. I honestly forget they�re on my head 90% of the time, it had clamping issues for like a day but then it went away, and the audio quality is amazing.


Very good sound

Very good sound but I have slight preference for Hifiman HE-400i. Headphones are ear of the beholder though - what one person likes another dislikes. See reviews before buying - these are classic headphones. They are very well constructed and look like they will last a long time.
