Clamp is spot on . not too strong. Overally the build quality is OK and accorded to the price. Sonically speaking, it's surprisingly good. Overally very engaging yet somewhat clean. Punchy but extended lows . Mids are not sacrified but I hear some hardness/shoutiness I'm sensitive to. Good sense of detail and clarity is there , openness is more than OK . I heard the Treble as harsh but not as harsh the measured 8khz treble peak suggests (and I'm allergic to 8 khz). Not a formula one of headphones but highly recommended for those who're after a cheap good headphone for themselves , family or friends. the TH7B is soemwhat not that easy to drive though. For people who like it loud and amp will be mandatory. the volume is cranked up close to the max on my laptop while I'm writing and I' usually don't listen that loud. Not much isolation from outside noises but leakage are almost inexistant. that's really an interesting point especially at work when you can hear the phone ringing without let know to everybody that you're watching pr0n. uh uh uh Will probably try some mods to see If I can smoothen the treble.
