TE-05 gives the Altone a run for the money. Yes, the TE-05 is about $25 to $35 more and it's worth. Just like the CKR9, the TE-05 is one of the few dynamics I've heard that has a BA-essence to its sound quality. Yet, since it is a dynamic, the overall is more natural and organic. So, okay, the Althone is kind of like the younger brother by a year and a half to the TE-05 in the bass department. The Fostex possesses a clearly cleaner and thicker and fuller bass (the sub-bass really pushes through) than the Altone. Both basses, however, are very clean and visceral. Both are so satisfying. The TE-05 also has a fuller and more organic sound than the Altone 200. Clarity is about equal (if its a little better in the Altone I having a hard time hearing it). The TE-05 is more 3-D in its sound with a wider soundstage. Both have great instrument separation. I think the TE-05's mids are bit more forward than the Altone, but the T-Peos isolates better if you're out and about. It also takes more juice to drive the TE-05. But out of all of the earphones I've compared to the Altone 200, I think the TE-50 and the Altone have more in common than any of the rest. It's like the the Altone could be the TE-50's younger brother. That's a very high compliment given to the Altone 200. Oh, I'm using Spiral Dot (JVC) tips on both earphones.
