So...last summer I watched the Yamaha HPH-200s dive in price from $150 to $67 on Amazon. I waited for them to 'bottom out' at $60. The remaining 14 sold out in one day, they shot back up to $150, then down to $100 for a day...and settled in at $150 for almost a year.
They're Yamaha's, so who cares, right? Well I'd heard & read some good things about them and wanted a pair of 'low-profile' open headphones for my phone/laptop.
Recently, they've gone back down to $79 and I picked a pair up. Glad I did; great sound for the $$...comfortable, solid bass for an open headphone this size without ruining the sound signature, very good all-rounders.
If you're looking for some <$100 open headphones, they're definitely worth considering!

The one negative (for me), only the white ones are at this price...
really should've bought them last summer.
BTW, only 20 left.
