Summary: Desapointing at the first run, this headphone needs a 24 hours burnin period. The first impressions were mudy sound with masking low-mid, recessed mid, and weak presence of the hi. After that period the sound is more balanced with improved mid impression, more natural low balance and very clean hi. This big headphone doesn't provide a good isolation. Hearing a mono pink noise may produce a hi-mid phasing because of the leaks from one hear to another.
Summary: A900 vs A900LTD? The physical changes are major and each alone has the potential for major sonic changes. Summary: A cord that keeps the grounds separate. The ground cord was an issue last couple of years as being able to make "huge" differences in sound all by itself. One reason people recable headphones is to get the grounds separate. This is not required for the A900LTD.
Summary: They are just great cans, and im not sure i can anything to whats already been said and my ratings, but... Sound - Must say even better. High's - Still very clean and concise, but the forced feeling seems to be gone. They keep up with some very fast J-pop, and dont fade from fatigue on the long notes in other music. They dont stumble through each other and just simply very clean and pleasant. Mid's - Still prolly the weak link, they are helped out with time.
Summary: I use this headphones for nearly two years. I'm quite happy with them...good all-around model (also for games and movies). My current sound source is: Creative SB X-Fi XG FPS > van den Hul Optocoupler MKII > Audio-Technica AT-HA25D My ratings: Bass Extension: 6 Bass Impact: 7 Bass Quality: 6 Mids Quality: 6 Highs Quality: 7 Soundstage: 7 Detail: 8 Portability: 3 Isolation: 7 Comfort: 8 Durability: 8 Improvement With Amplification: 5 Value for money: 7
Summary: My favorite headphones by far. They are very neutral sounding so the bass is not pronounced at all; however, it does go low and sounds great all the way down. Highs are amazing with a proper recording and source. Honestly, these headphones gave me chills when I first got them, they really do sound as though you were in a live performance, at least with orchestral music. Again, the bass extends low, but is not convincing of a live performance.
Summary: The A900s are very good headphones for the money. I have compared them directly to CD3000s and find that these are quite similar sonically. The bass has good impact, but sometimes doesn't extend as far down as I would like it to. The mids are somewhat honky and lifeless, but this is overall a very fun headphone for use with all different types of music.
Summary: Let me start by saying these headphones need a huge burn in time. I honestly believe it took near 300 hours for these to fully open up and show detail within clarity. I will review these along with the rating. Bass all around is decent, but the worst part of these headphones. In short if your looking for a large amount of bass these aren't the headphones for you.
Summary: These are very comfortable headphones that are easy to wear for extended periods. Bass reproduction is strong and excellent, without the boominess sometimes associated with closed 'phones. Despite much talk of "recessed midrange" with this model, I have found the biggest problem to be a definite rolloff in the upper frequencies. This becomes apparent when listening to music incorporating high-hat cymbals or other high-frequency percussive instruments.
Summary: I've owned this headphone for about one month. It's sound is colored, but it gives the headphone warmth and is very pleasant to listen to. The sound is different from A1000 and more like other old ATH headphones.
