Well yes and no. The clamping is less on the HTF600 but the pads are quite stiff, I did however have slight issues due to clamping force with LP2 as it didn't fit fully around the ears but this is something that probably would disappear with time or if I'd stretch it a little while HTF600 fits nicely around the ear. But yea I've never had issues with HTF600 as the clamping force is so light, I can wear it for hrs and hrs but it can get a bit sweaty, LP2 didn't seem to thanks to the memory foam pads (I really love memory foam and wish every headphone had them), so soft and cushy and doesn't seem to get too hot.
The HTF600 won't win any sturdy or beaty queen contests, from build quality point of view it's like worth $20 max, but damn these packs some great sound quality for the price, they never cease to amaze me, so engaging to listen to and works pretty well with every genre (I boost the treble just a very tiny bit), I can never seem to sit still with these headphones on. LP2 came close with the optimal EQ settings but wasn't quite there. The HTF600 isn't quite as bassy as the LP2 but packs still a sufficient bass quantity for bassheads and once you hear the beautiful mids/highs you won't be missing that bass of LP2 even as a basshead. (well I use ZO so can get them both to that similar level of bass I prefer anyway) but the bass quality is better on HTF600 though, probably the best quantity/quality ratio I've encountered so far.
