Summary: We bought our 1st generation pair from Newegg on sale for about half the current price and at that price they weren't just good, they were phenomenal: clear and even throughout the frequency range, with the other advantages described above.
Pros: Price when on sale at less than half what the current price here is (if the price here was that low I'd have given them at least one additional rating star). Light-weight and comfortable (not too tight but tight enough to stay in place even during moderate exercise). Single cord to the left earph...
Cons: Mid-range and bass are a bit muddy, bass is kind of boomy as well. High range is fairly clear but not exceptional. A bit delicate (our first-generation pair broke at one hinge after 4 years of light use, and the new pair appears to be identical in that area).
Summary: Bought one pair for myself for travel, and now I'm buying another pair for my husband. I was amazed about how good they sounded in a crowded waiting room amidst public address announcements and crying babies.
Pros: efficient, great sound, played some halestorm, sounded better than my klipsh ear buds. yeh yeh they are not comfy, look cheap, but for 11 bucks outstanding. probably would pay the 30 dollars just for the sound.
Summary: I got these on sale for about $10 and was still disappointed with the performance vs the price. I actually went out of my way to destroy them when I threw them out, because I figured I would have no use for them and most people I know wouldn't either. There are far, far better headphones for $20.
Cons: 1. They feel just as cheap as they are; people will hear your music if it's playing loudly enough as well. 2. Very small, wouldn't even fit my (somewhat-large) head. The headband was too thin, to boot. 3. Uncomfortable, chafes my ears, doesn't feel good to wear at all.
Summary: Black Fri price was awesome and really these are worth at least 30-35. Work great on phone, laptop. More base than treble but not too much, almost right. Bought to use on airline and they are excellent for the price cause I'm not spending $200 on a pair. No disappointment whatsoever.
Pros: Price. Sound quality. Comfort. Compact.
Cons: Swivel Earpieces could click in place better.
