Went to my local Sony store to try these out, and found them to be very bassy as advertised. I found
HiFiGuy528's reviews to be very accurate.
I went with the intention of picking up the XB400's for my wife as a closed-portable, and for me it was the most impressive for the money, considering it could be had for just under $40 on Amazon. The XB600 and XB800 were pretty good, but I wasn't convinced they were worth their asking price. Also, talk about total fart-canons.
So in the end I ended up paying a bit extra for the Japanese imported red XB400, since they really look good and I wanted my wife to be really happy with them, and I'm fine with that. But the story doesn't end here.
Yesterday morning, I wake up to the Amazon lightning deal page (I have it home-paged) and there are the XB600's on sale 60% off, for $39.99. I caved like the weakling I am and cried in the corner wondering to myself what I've done.
Well, the XB600's are on my head right now, and the biggest curiosity for me was when HiFiGuy528 mentioned in his XB600/XB500 comparison that the XB600's vastly improved when plugged into an amplifier. And man, he was right.
The bass is very much right there in your face, and unamped the mids are definitely in the backseat and the highs are quite slushy. Plugged into the FiiO E7/E9, the bass flab really tightens, the mids are pushed forward a bit but still recessed as to be expected with a bass-heavy can, and the treble becomes much much more crisp.
Another concern that I was worried about which led me to try these out in store was the on-ear design. I was skeptical at first but the first thing I noticed was the isolation. I wasn't expecting a seal of any kind, but that's what happened. Boom. So that was a pleasant surprise. The ear pads are quite comfortable.
In summary, my initial impressions for the XB600's are as follows:
- Great ambient noise isolation due to on-ear seal design.
- Ear pads are comfy, but could be fatiguing over long sessions. Will have to revisit this with more time.
- Bass dominant, recessed mids and washy highs unamped. Decent portable.
- VASTLY improves with amplification. Tight bass, mids less recessed, and highs become crisp. I can recommend these based on their amplified sound.
- The need for amping kind of puts a damper on the XB600's portability. Portable headphones should sound great unamped, and even better so with an amp. This is why I decided to buy the XB400 for my wife.
- I wouldn't pay $99 for these. $80 is more realistic; I think $70~75 is more fair. Remember, I paid $39.99 for these, so I'm extremely happy with the value I got.
- These also look GREAT, better than they do in photos.
I'll post impressions of the XB400's when they come in; they're taking a bit longer to come in since we got the Japan-imported red version.
