    ATH-AD900 Audiophile Open-air Dynamic Headphones 5 5 1 1
    Crisp clear reproduction 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).

    Open vs. Closed back regarding sound quality.

    Since both the closed and open designs offer a wide sound scape, which would be better for hearing the smallest details in a composition. I'm looking for the best quality in sound and I heard that open backed headphones will give out a better sound quality. Is this true? Also, how bad would you expect the sound leakage to be for the ATH-AD900?

    Answer: 
    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.

    They do have the best spacial reproduction of any headphone I have used, and the detail is excellent - I hear detail in my music that I had never before been aware of.

    The sound leakage is significant - no attempt is made to shield the large drives from the outside - just an aluminium honeycomb casing between the driver and the world.

    The other thing to be aware of is that they are very large. About 4" in diameter across the earpieces.

    Answer: 
    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.

    Answer: 
    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.

    With this however, is leakage. You would not be able to use these in a library, the AD900's or the 700's. However it's generally not obtrusive to those around you either. For example, my roommate never minded and we shared a room. Please note that you will also be able to hear those around you as well, there is little to no isolation from the outside.

    You're going to be able to monitor and hear the distance between instruments notably better with the open air style headphones.

    Answer: 
    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.

    ATH-AD900 vs. ATH-A9/700 vs. ATH-AD700

    I am currently looking at the ATH-AD900 and the ATH-A900 but I have no idea whether a closed back or open back would be better. I do not listen to music with heavy bass and am wanting something with a very large sound stage. What would be the best choice for this.

    Answer: 
    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.

    I think these phone will give you the large sound stage you are looking for.

    Answer: 
    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.

    Answer: 
    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.

    Consider this, you have any problem with these incredible sounding headphones, such as a short in the wire- and it can be fixed simply by sending them in. The work I have had done by AT has always been professional, prompt, and best of all- affordable.

    Answer: 
    Thank you for your inquiry!
    Yes, we do have many options that fit that demographic, but it depends on what they might be looking for. Here's a few suggestions:

    For her: we have a line of FashionFidelity‚ĄĘ headphones that are perfect for anyone looking to put some bling in their wardrobe. We have everything from pretty pastels to hard-rock jewel cut designed headphones. Not only are they fashionable, but they will also sound great. Click on these links for more info: http://www.audio-technica.com/cms/h...; http://www.audio-technica.com/cms/h...; http://www.audio-technica.com/cms/h...

    For him or her: our Solid Bass line of headphones has punchy bass without sacrificing the quality of the music. While some competitors find it ok to reduce the high and mid frequencies while also making the bass sound muddy and distorted, we keep the music in tact while enhancing the bass. Click on these links for more info: http://www.audio-technica.com/cms/h...; http://www.audio-technica.com/cms/h...

    For you AND them: Our line of noise-cancelling headphones are perfect for the age group you're referring to. They use circuitry to cancel out ambient noise allowing for better concentration while studying or to block noise while traveling on a bus. And because the circuitry cuts the background noise, this means they don't have to listen to their music as loud, so they will be less likely to damage their hearing. Click here for more info: http://www.audio-technica.com/cgi-b...

    For fun: we have a line of colorful portable headphones that are so affordable, you can buy a different color for every day of the week! Click here for more info: http://www.audio-technica.com/cgi-b...

    I hope this helps! Good luck!!
