Superlux HD-660 Pro 32 Ohms

These headphones look, sound and feel great. A step up from my old, withered ISK HP-580, they have good isolation and feel more comfortable on the head, too. Metal headband, soft, leather-like cushioning and velour pads. The cable is not very thick but not overly thin either. Height regulation is VERY stiff but it's mostly a one-time setup anyway and maybe it will give in with time.

The 32 ohm version is VERY easy to drive and I'd say much more suited for use with weaker sound cards. If you have an audio interface you're better off buying the 150 ohm version, otherwise you'll have a narrow range of usable volume knob and noticeable channel imbalance.

The sound though? Amazing. These are the headphones where I basically gave up to set up any equalizer for at first - they just naturally sound really nicely. Calm, not overly bassy, highs are somewhat muddy (but a crystalizer helps with that), the scene is not amazing, but it's not non-existent either, decent considering these are closed-back headphones.

I don't have HD330 Pro to compare them to these yet. I assume they would be even nicer with punchier highs, but if you need isolation, 660s are there, too. Worth the price.
