They are well made, and extremely light. I can wear them for hours.
Initially, they seemed a little "light" in sound as well, but after a couple of weeks usage, they seem to have rounded out, and I can say now that they are incredibly tight and precise in the highs, and clear and well spaced in the mids, with crisp and balanced bass.
I hear things in these phones that I have never noticed before, even in some of my favourite recordings. Warning - not all music is created (in the studio) equal. You will be able to tell the difference between indiffferent and excellent studio work.
I use them for classical music, and I can really locate each solo instrument in the ensemble - I can close my eyes and it is as close to being there as I have heard in any headphones.
The only negatives I have are the size - impractical for outdoor use, and the clean bass is not to every musical style.
They are also not noise cancelling in any way - in fact that was a plus for me, since I use them at work, and need to hear when my colleagues are attracting my attention, and at home when I am babysitting (and need to hear when my three year old needs my attention).

Q:I am buying headphones for my kids who range in age from 13 to 27. Do you have a particular model that is selling well to this demographic?
A:The M50 DJ Style headphone go above and beyond in terms of reception within that age group. Not only are are they professional grade headphones, but the bang for the buck considerably outweighs many of the more mainstream popular headphones.
A:Thank you for your inquiry!
Q:Open vs. Closed back regarding sound quality.
A:I have the AD900s and I really like them. They do not noise cancel at all - which for me is good, since I need to hear when people (and my toddler) are trying to attract my attention.
A:Opens definitely offers a wider sound-stage and they don't have the reflections that a closed model has. I have the AD-700's and love 'em. They do bleed sound though. That sound that's not being reflected back toward your head in a closed, comes right out of an open design. Opens also allow sound in from your surroundings more than closed models.
A:Actually, the open designs offer a considerably wider and broader soundstage than closed back headphones are capable of- simply because the back of the driver is exposed.
A:Thank you for your inquiry. Many people have the opinion that open back headphones sound more natural, closer to the sound of listening to stereo speakers. For others, the sound isolation provided by closed back headphones is more desirable for, of course minimizing outside sound, but also allowing one to hear more detail. Open back vs Closed back is definitely a personal preference. As for sound leakage with the ATH-AD900, we do not spec this, but it really depends on volume of the source.
Q:ATH-AD900 vs. ATH-A9/700 vs. ATH-AD700
A:I purchased the AD900s based on reviews on various sites, and I cannot say I was dissapointed. On the contrary, I was amazed to hear details in music that I had never noticed before, and the spacial clarity is astonishing.
A:Definitely open if you want as large a soundstage as you can get!
A:Either model may meet your needs. Both produce a large soundstage and do not over-emphasize the bass. The intent of the open-back design is to produce a less colored low end by venting any resonances that may build up in the driver cavity. Keep in mind however that this venting also allows sound from the headphones to leak to the outside. This sound could be picked up by an open microphone or disturb others near you. The open-back model will also provide less isolation of outside noise compared to the closed back model. There is the potential for more noise to reach your ears while listening.
