This is the second pair of these headphones I have purchased. I have used other headphones in the past, but never been satisfied with the sound. The dynamics of the DT100 are superb allowing every note to be heard clearly wether used as a mixing desk monitor or musicians headphones. They are comfortable to wear even for long periods and keep unwanted sounds out for superb clarity. A top quality product that I throughly recommend for technicians and musicians after perfect sound quality

I've used Beyerdynamic DT100 headphones for a number of years, in my music studio.
I find them very comfortable, even when wearing them for hours on end.
They have good sound isolating qualties, and a wide fequency response.
As my mixing console will only accomodate 2 sets of headphones, and I often require more, I have invested in a headphone amplifier, which will allow me to employ a further 4 sets of headphones.
along with the headphone amplifier, I purchased 4 sets of, what was described as 'studio headphones', but found they were no match for the DT100's, so I promptly returned them, and will be ordering DT100's in their place.
To sum up, Beyerdynamic DT100's are comfortable, and live up to their specification.
For studio work, I wouldn't use any other headphones.

I bought a pair of these from Dolphin music in Huddersfield, and I've got to say this is money well spent. I was going to opt for a much cheaper pair originally, but after doing a bit of research/reading some reviews (and the fact that nearly every photo you see of any musician in a recording studio they will be sporting a pair of these !) I decided on spending a bit more and getting a pair of DT100's. What can I say, I'm very impressed with the overall sound of these, the closed cup system really does exclude any ambient noise, their comfortable to wear over long periods of time, their well made and very rugged. I'd recommend these to anyone thinking of buying a quality pair of headphones, I can't fault them.

If they were good enough for the Beatles (and everyone else ) then they are good enough for you. I bought a pair of semi open AKG 240s from Dolphin a while back and they are the best headphoines I've ever had for mixing but they don't give the isolation for recoding anything acoustically - vocals, acoustic guitar. Everyone but everyone uses DT100s they are absolutely the best closed headphone buy you will ever make - look nowhere else.

Rugged reliability, user servicable components and a well balanced sound make the DT100 the absolute, hands-down studio standard. Aesthetically they are far from attractive and look more like ear defenders which gives you some clue as to the design feature that helps eliminate outside noise.

So how do they sound? In short, well balanced bass & treble but with a noticeable peek in the mid range. In greater depth, if you are after an audiophile experience with rich bass, smooth mids and crisp trebles, you'd be better off buying a pair of £30 Sennheisers!

That said, the overall sound is detailed and more than suitable for the job of monitoring during recording. Although you should never mix using headphones, sometimes it is the only option. Given the DT100's mid frequency boost, I wouldn't reccomend mixing with these phones unless you have some A/B material to hand. If not, your mixes will translate with a noticeable mid presence.

Finally, do you go for the 16ohm or 400 ohm version? I opted for the 400ohm and found it worked well with my NAD amp and my Mixer output but, plugging into my soundcard gave a thin, quiet sound. If your going off your soundcard then the 16ohm option is likely more suitable and will doubtless also work well with MP3 players and other portable devices. For Hi-Fi & Studio use, the 400ohm option will suit better.
