More expensive and more drivers doesn't always mean it's better, but most of the time yes.. But usually there is some level that u already satisfied, and at the end of the day, that justify your money worth spending.. I mean, if triple driver can satisfy me, I wouldn't go for the 4 drivers which is of course more expensive..
I'm still observing the XBA3 sound signature.. Hurmmm... Not sure if I like it.. To my ears now, my cheaper re400 is more lovely..
Anyway, a quick note about sbh52.. I can hear degradation of sound quality when I play music thru sbh52 than directly plugged into the phone.. It takes down the level of details, mixed the sound to be a bit muddier, and take away the lowest rumble and the highest chimes.. As expected, a bluetooth audio device is not able to retain the analog sound signal properties, rather losing much of the sound quality white it converts it to digital.. In spite of that, sbh52 is the best bluetooth audio device I've ever tried, at least the sound still enjoyable, but the previous device that I tried sounds were totally crap that I couldn't bear off.
XZU audio sound is quite low. Most of times I play at full volume or slightly lower.. Damn I hate it.. While I can't bear full volume on my ipod..
thank you for the review.
i guess i will be getting the re400.
