Conclusion: This is definitely my favorite. The sound is fairly balanced across a wide MHz spectrum. The mid-range is clear and the bass ample. I much preferred the 40mm driver AKG Q460 over the 50mm driver AKG K550 and over another 50 mm headphone I'm familiar with, the Sony MDR XB-800. It is fairly light and very comfortable to wear. They did not need a lot of power at source (i.e. battery) to sound good. I highly recommend them.
Summary: These headphones can be had for under $100ish new on Amazon. Can be found for far less, I paid $60 new.
I really like these headphones. I am not the best judge on sound quality though since the best headphones I have had are M50's. The other reviews I have read say they are a little bass heavy (which I can hear) but overall I like the sound since I enjoy bass.
Pros: Looks good, sounds good, comfortable, good deal.
Cons: SHORT CABLE IS STRAIGHT GARBAGE, umm ya the cable is really short.
Conclusion: I recently left my pair of Q460s on a plane and have been sorely missing them. I own many sets of pro headphones in my recording studio and am quite spoiled by them - so when I needed a pair of portable 'phones my standards were already very high. These headphones delivered on all counts; price, quality and clarity w/out sacrificing full-range sound. They are not overly bass emphasized (like the Monster Beats line) but they do have a solid low end.
Conclusion: Wow, I must say I disagree with "BASS's review". I have heard every Beats headphone on the market. The Studio's are a different style. Designed for Bass with an amplified driver and noise cancelling. The Pro, well they are excellent. But the Solo? You've got to be kidding me. Those Solo headphones are little puny attempts at a fashion statement at best. They are empty and sound lifeless on any type of recording worth listening to.
Summary: There is no doubt that the Q460s are way ahead of alternatives like Beats by Dr Dre, but they are similar in that they don't suit all music types. They're great for Hip-Hop / Rap, Electronica, mellow Jazz and some Rock, but they don't fare quite as well on more acoustic genres.
The upper end of the mids get a little bit pushy on certain vocal tracks and the treble is a bit understated which can lead to a lack of detail and sparkle.
Summary: The test for personal headphones is always how they sound to the end user. One person might prefer Senns over AKG, another might prefer Grados. When I was looking for portable headphones for my phone, I checked the selection at my usual store, Bay Bloor Audio in Toronto. The AKG 450 sounded better to my ears and for my purpose so I bought them and loved the sound. I still do.
Pros: Very good sound, light weight, low power requirement
Cons: Cabling is unacceptably poor quality and spoils the experience
