I have to agree with the Proggers, the HD-25-II is probably the best closed portable in the under $200 category to my sound & genre preference (analytical, 80% indie rock).
But I would never use these for exercise. These would also be a bit awkward for running. They’re not full-sized but they’re not miniscule, like the px 100. And, the thought of sweating on my $200 cans is just… upsetting.
I might add, running is one of my hobbies, and I do all of mine outdoors. Tread mobiles just feel unnatural, and my local gym is a total meat market so I try to spend as little time there as I need too. For my purposes, I settled on the pmx 680 (replacing an omx 80.. fit was dreadful).
- Size comparable to Sennheiser PX100
It’s tiny, cord is same length and the px100-II so slightly shorter. The cord also separates at the volume control for armband use (huge plus for runners).
lighter than a pair of sunglasses, once they're on they stay put and just disappear
Comes right off and rests on your neck
16 ohm, I drive them out of my evo 4G without issues, actually, the lowest volume setting is usually all I need.
- Sounds at least as good as Sennheiser PX100,
I have the px100 I&II. These are tuned similarly(maybe a little brighter?). The bass and mids can be very forward if you push them in all the way into your ear.
Doesn't isolate too much.
No isolation problems here, they’re buds. If you want more isolation push them in all the way but you’ll have to deal with some muddiness.
Look, I realized pretty early there’s no one headphone or iem that will do everything, there’s just right tool for the job. These are sweat & water resistant (washable under running water), have a Kevlar cable with a strong L-jack.
Since your budget is $200, you could get these, and still have $170 to buy something for everyday use.
Here’s a link to where I bought mine:
use coupon code: TECHBARGAINS
and the price will drop to $27.15, shipping for me was another 5 dollars, so $32 shipped
Actually, they have an open box Adidas hd-25-II going for $170, so for $205 + shipping with the same coupon, you could be set =P. But I'd probably spend some time on these forums doing some research to find a can that fits your individual preferences.
And you might want to read this review from headfonia.com that got me interested in the 680s. The reviewer actually uses these as portables rather then exercise cans because of the design.
