Good, but for short periods of time.

The headphones provide you with nice quality sound for that price. They have fairly good sound isolation from outside - I have to put them down to understand someone. However, after an hour of listening my ears start to hurt.
So they are very good for short distance listening, but not for longer.

These are pretty cool, but they don't last very long.  If you play your guitar pretty regularly, they will start to wear quickly

This worked very well for a few months. I added an external antenna to help boost it's range which resolves the most painful issue most people are having.  But after a few months of being plugged in, it just stopped working. I think you are supposed to disconnect the power when you are not using it, but i wasn't about to do that.

The sound is good. Definitely a step up from a pair of cheap $20 earbuds. However, the wire-from-each-headphone had a tendency to tangle. The wiring near the headphone itself was a bit thin as well. After 5-7 months of use one of the headphones stopped playing noise. Admittedly I put it under a bit more stress than the normal user: I used them when cutting my lawn in the summer (humid, sweaty), I used them in the rain a few times, and I even ran with them once... so make of my build assessment what you will.

This thing was awesome for about 3 months before it started to fall apart. The color and design were on point, but it had a weird smell to it that lasted about a month. Its short lifespan is kind of expected with its low price so i cant really be to harsh. tl;dr it was worth it

Worked great for a while, but now gets a glitch sometimes where it lets out a quick, loud, short burst of static (for lack of a better description).

They didn't last very long, but were a good buy.

Good concept, if they only lasted longer.  We've had 4-5 of these and seems to not last much longer than 6 months, even after new batteries are put in.  But we keep buying them because we like the amount of light these emit in the middle of the night.  Enough to light the way, but not so much that the light wakes you up.

It worked great, for a few months.  Still works but the roller skips.  Not bad for price but I'd buy a few at a time because it seems to wear out quickly.

Like many of the other one star reviewers, my lights ceased to function after a few months. The ones that get used much less (are in low traffic areas) lasted longer, but the lights that get used frequently dimmed over the course of their life and then went out completely. These are awesome when they work, but that if short lived.

I bought these headphones for use with my iPhone, and for occasional use with my computer (via Aux cable). I was, at first, impressed with the sound quality and the long of the battery. With steady use the charge lasted me several days, and standby time was also greater than expected. They were mostly comfortable, with only some light irritation after several hours of use.

After only a few months of use the headband broke. It could not handle my head size. I still use these, but I need to keep them on using a baseball hat. I will be searching for a replacement soon. I wish these were more durable as the other features are great. If you have a small head perhaps these will last longer for you.

I have had about a half dozen of these and they work well until they quit and then it is time to replace it with another one. I always keep a spare handy because they do not last much more than a few months. I will keep buying them because they are inexpensive.

These headphones were great when we first got them back in May. The sound quality is great considering the price. The are comfortable to wear for hours at a time when running (I average about 30 miles a week). They stay in place and don't hurt my ears. They held their charge for a good 5 to 6 hours when fully charged.  5 months later however, the headset wouldn't hold its charge for more than an hour maybe and hour and a half (after charging all night),  one of the wires that loop behind the ear broke so now it doesn't stay in my ear if I move too much, and a month later they won't charge at all anymore.  I guess it did hold up well considering the mileage but I would have liked for them to be more durable. They were great while they lasted.

The product is really nice when you start using it at the beginning, but it will start to get kinda loose after a while, and won't stay straight on your bike, don't recommend it for long term use. But it's good for a month or so.

It worked pretty well for almost a year. I used it extensively and found the audio was generally very good. I did notice that different bluetooth devices had better range with it, with some devices corrupting the audio at a shorter distance than others.  Overall, I was very pleased with it.

I will say that the size is a little small for my head, so I always used it fully expanded and it would still have to stretch out a little bit. I think this caused it to wear out faster, because today when expanding it, the left side of the band, just about the extension piece, the part where the most flexing would occur, snapped.  The bluetooth still connects and the sound still comes through, but the cups are not snug any more (obviously!) which makes wearing and listening to these headphones very awkward. I was able to use some duct tape to repair it, and it's going to limp along for a little longer.

That said, these were fairly cheap and lasted me for 11 months. Used for 8 or more hours most days of the week during that period, I'd say I got my money's worth out of them. I'll definitely be looking for wireless headphones again, but I might try another brand or model to see if I can get one that will last a little longer.

My wife and I are renting an apartment because we are students, so we were looking for temporary bedding. This bed turned out to be a good solution for a while, but then round seamed parts on top started popping out one by one over the course of a couple of months. We had to flip over the whole thing and use couch cushions as crutches for it so we could sleep on a flat surface, but eventually one of the round seams popped a hole while we were sleeping and the air was gone in a matter of seconds. We are barely over 300 lbs combined weight, so I would have thought the mattress could take us longer.

Pros
-pretty tall
-easy to air up
-good size
-light (it's an air mattress)

Cons
-only lasted about 6 months (started breaking at about 4 months)

I would recommend this if you only plan on using it as a backup or guest mattress, just make sure you have something soft you can put on top like a thick comforter, because the top seems kind of bumpy and cold when it's bare.

Nice bulb, great features, but it didn't last that long.  For a bulb that goes on once in a while I expected it to last several years, but this didn't make it 2 years...probably less than a 250 running hours
