Just wanted to chime in as an owner of LP2s: they are not fantastic, to be honest. Are they bass-heavy? Absolutely. Does the actual SQ live up to the price? Not really. They were my very first >$100 headphones and I loved them when I first had them. Picked up a pair of AD700s to try out an open can and the difference in sound quality was huge. Not to say they share a similar sound signature, but the LP2s simply just had nothing going for them. Muddy but substantial bass, very recessed mids and uninspired highs. I personally would not recommend the LP2s over the similarly priced M80s or for $100 extra, the M100s which are extremely fun headphones for bassheads.
But this thread is ~$200 BASS HEAD focused, the M-80s are not to be considered bass head cans, and the M-100s are $300.
As for your experience with the LP2s, I will most likely have a similar one. I love mine right now, them also being my first high end headphone above even $50. But I plan to make my next purchase a pair of DT 770 Pro 250 Ohm, along with a Fiio E11. Ive heard MANY people say that the 770 Pro 250 is an amazing bass head set, while not losing the fidelity for highs and mids like the LP2s do.
Personally I wish I would have payed more attention and gotten the M-100s or the UE6000 instead of the LP2s, but its too late now.
