UPDATE -- Sept. 17, 2018
Bought these in January 2018 and by the end of August stopped working. Out of warranty. They weren't expensive but I only want them for audio books, I'm functionally blind and unable to read print without complicated electronic aids. If these headphones had lasted at the very least a year I would have updated with a 2 or 3 stars. I recently purchased KOSS UR 20 for a few dollars more and I like the fit and look better (also an 8' cord) and I hope they get longer trouble free use.
Sound quality is acceptable. If you're an audiophile, then you won't be satisfied with the quality. I use them for video streaming, video games, listening to music, etc and it always seems ok to me. They don't drown out external noise much though, so if you're in a noisy environment, it's not going to work out well.
The price makes it a steal pretty much given the brand and the quality it provides. It's rich with enhancing features such as the longer cord that allows for more movement (was a must for me, the short cord problem I had was starting to drive me insane), surprisingly lightweight (than was expected ) which will make longer sessions more comfortable, plush padded ear pads for more comfort. Hell I'll probably fall asleep in them sooner or later with all this comfort lol
Bottom line it's a solid, honest product from a quality brand. What you see is what you get. Can't ask for more than that.

I've actually bought many pairs of these headphones for myself and others, and all have been of very high initial quality, and of good durability, with the price ranging up to $12 and back down to around $7.
Its hard to evaluate sound quality, and I have never had the desire or cash to spend more than $25 on headphones. But for the price I have been very happy--I've never said to myself, "I wish these were louder," or "I wish these sounded different," or anything else like that. I guess my thought is that if you know enough to critically evaluate a pair of headphones beyond those two questions, you probably wouldn't buy them on the Internet where you can't listen first. I've bought a couple other pairs of sub-$10 headphones for my wife and kids, and these are the loudest, best and longest lasting, but they insist on earbud style so they haven't switched to these full time.
I don't like in-ear headphones because they tend to fall out of me ears, and eventually just get uncomfortable after an hour or so. I guess I have a sensitive head, because I have quit using other headphones before because they squeeze too hard or the foam doesn't do its job. These are comfortable enough for me that I can watch a movie on an airplane without discomfort.
For a decent pair of headphones, you won't go wrong here. There may be better choices, but after listening to a couple other pairs that my family uses, if I needed a new pair of headphones I wouldn't even look at anything else.
As for durability, these have been very good for me. I'm not a person who uses headphones multiple times per day, so I can't comment on how durable they are with constant, heavy use.
They work well and I'm glad I only purchased them for $10.
The bad:
They are extremely uncomfortable to wear. They are not shaped for a human head and would probably fit a box better. I hate wearing them, but fortunately I'm only using them for 30 minutes or so at a time. In addition to being uncomfortable they are surprisingly heavy. Not worth returning, but certainly a poorly made product.

Muy ligeros, cómodos y con un audio muy superior a lo que su bajo precio y anticuado diseño sugiere. Si estas buscando remplazar unos "chícharos" intraaurales sin gastar mucho y obteniendo un sonido superior, tu búsqueda a terminado.
