A+I am entirely unsure about these for the sake of bulk I would’ve argued the price and sound quality made it worth it however at least half of them have weird issues some of the ox cables are unhappy unless they’re resting in a specific way and then I can confirm at least one of them one of the earpieces wasn’t working I have not trained on every single last pair so from what I can tell I really wouldn’t recommend these overallOne thing I feel I must add is that I do like these type of headphones they sent use nicely and there are no irritations but I would look for some that are similar somewhere else for the fact that these had as many issues as he did that’s really my only real beef with this and that’s kind of a problemExactly what was advertisedWorks better than the $10 I paid for a single pair of ear buds on Amazon.Product was not as pictured. They may have worked well, but I needed them for a project and needed exactly what was pictured, so I returned them.Doesn't last longAround ten percent of these were outright defective. One or both earbuds wouldn't work. The earbud wiring is also really fragile. The plastic is large and hard against the ears. They are not comfortable unless perhaps you have jumbo sized ear canals. I wouldn't really recommend them wholeheartedly, only if you really needed them for a large number of people who didn't bring their own. If you need something of higher quality, spend more elsewhere.These earbuds are inexpensive which if you break earbuds often, makes them a consideration. First pair used one of earbuds has a extra buzz while the other was clear when the volume was increased, Also one side seems to have more bass volume than the other when listened to by the same ear. Buds are identical in shape, no left or right so some users may be used to other manufacturers that have ones slightly off center design.Good price and prompt service. These are not especially sturdy but they are good value and, with care, will last a week or two.I thought I'd try the bottom-of-the-barrel price headphones for work, I paint, just something that if I got 4-6 months out of, great.These are just crap. Skinny, fragile little wires with no casing that will stand the use of even other bargain HPs I've used that lasted months and months.I plugged the 1st one in and nothing. Wiggled and some sound, then nothing. Tried a 2nd. Same thing. The head phone jack does fit will in my iPod nano.Won't even give them one star. Avoid these for all but the most minimal application. I get the cheap construction, but the two-in-a-row fault jacks? Substandard and unacceptable.Sent'em back.These earphones are not high fidelity but for the price your not expecting that. I find they are great for just listening to podcast etc and loudness does not seem restricted.Maybe good for little kids. I found them to be very quiet and the sound was muffled.This product is worth the price. They are not the best quality but as a teacher who needed over 20 it does the job. I do not expect them to last the year but good enough!
