Have two of these for sale. One in packaging is for $6500, the other is used for a day and for $5500.
Both have all accessories (earcups, clip and pouch)
As you all know, XB stands for "Xtra Bass" and these headphones produce wickedly brutal BASS!!!

Better lows and mids than the MH1-Cs and comes with the pouch.
Excellent sound condensing. 13.5 mm driver and the frequency range is 4Hz to 24kHz!!! There is more impedance (16 ohms) than the MH1-C headset but the bigger driver ensures even the minimum volume of your phone will produce excellent sound quality and loudness. Paired these with an Xperia Ion and a W995 and even songs weh mi just nuh like I started to listen to

These are not noise canceling but outside noises are almost non-existent! Don't know how Sony does it.
For people who use their phones to listen music constantly, you CANNOT get better than these without spending > $20,000 trust me. No beats can compare to the sound quality and the sweet sweeeeet low frequencies and bass.
