HD-650 burn-in? - Page 2

post #16 of 46

hd650 has the potential to sound really great but definately need some hours on them before they sound that way.

when I first got mine I couldn't believe how the made everything sound lumped together, after  many hours on them instruments and vocals get separated out nicely.

Exactly, 'lumped together' is a good description, everything was sort of in the middle, then it started to open up.

Now they sound great, after about 6 weeks of use! 

 

Someone posted that they are called 650 because that's how many hours they take to burn in, honestly, that is fairly accurate! 

 

Really surprising that it doesn't mention this in the manual, something like, Congratulations on purchasing the Sennheiser HD650 reference headphone, you'll notice that they sound **** but please use them for 650 hours before returning them for a refund!

 

I wonder how many people have sold them on or refunded/exchanged them before hearing them properly burnt in?

Final post regarding the HD650's, they sound fantastic, brilliant in all departments and possibly the best audio quality I've ever experienced, it takes yonks for them to get there but well worth the wait.

i had the project headbox II with my first pair of hd 650. however it was the project headbox SE II which has more power than the regular one.

 

however, either one should work well on the hd 650. it had good synergy imo and don't remember any distortion whatsoever.

 

perhaps the smaller one might not be as good though.

I hope you're right. I've had them for about 4 days, maybe 40-50 hours of total listening time just listening to my music as I normally would.

 

At first they sound "lumped together" as you said, then they opened up a bit and sounded fantastic. This could all be in my head though. 

 

However, now I feel like the songs that sounded amazing with lots of detail yesterday are lacking and there is even some distortion at times, extremely annoying. . This cannot be in my head. 

 

If they keep sounding like this I will certainly return them. But I've read a lot about how they take time to settle and I still have about 2 weeks to return them.

Took me 2 months day night running to really stable down to the sound I've heard in the shop display. Now it sounds okay even with my cellphone.

Oh yes, I find that if you don't burn your headphones in for 1500 hours first, they'll never quite sound like the ones in the store you heard months ago which probably had at most 100 hours on them already.

My HD650's sounded wonderful out of the box, I have noticed no significant change as I've listened to them. I didn't expect change, and I didn't hear any.

post #25 of 46

Honestly, give at least a month of regular listening, they will be different headphones. I wouldn't give mine up for anything now.

post #26 of 46

I will. I mean these are by far the best headphones I've heard in my life. Even though that's not hard when all I've heard are some other Sennheisers, crappy Sonys and the Beats. 

 

But I was expecting a little bit more though. I hope this will change. :)

I think a factor with the 650s is they are different than most other headphones and it takes a while for one to get used to them.

post #28 of 46

I was just about to post that if anything, the change could be from people becoming accustomed to the sound signature.

I do think they take time to get used to. . . just not hundreds of hours. rolleyes.gif

 

Don't just listen to them for an hour and sell them, that's for sure.

I could have sworn that the HD 650 only needed 1200 hours of burn in, after the first 1200 they reallt opened up, and the the mids suddenly became sweeter then ambrosia, the trebles as crystalline as the purest diamond and the bass as deep as the Marianne Trench. I can't wait for the 1500 hours mark when angels are said to descend from the heavens.
