Good for the price, but the clips wear out

Up until very recently, these have been my go-to running headphones. They are functional; they provide adequate fit and sound quality at a good price.

Over the period of a year's use, the clips that hold the headphones close to my ears has worn. It no longer holds the headphone snug to my ear, thus it just kind of hangs / bounces from the top of my ear while running. This deeply affect sound quality and is quite annoying while running.

While the clip was working as designed, I enjoyed them very much. After the clip stopped holding the headphones snug against my ear, they were thrown out.

GOOD FOR THE PRICE, BUT WILL STRETCH OUT EASILY

Great lights but the clips are almost "junk". They break if you're not very careful. Also, the light assembly catch seems to wear out after a while and will not anchor well into the body.

This is my third clip.  The first one lasted almost 2 years, if I recall correctly.  The second one lasted only about 6 months before the plastic at the end of the clip cracked and broke off.  I can still use it, but eventually the metal that was exposed will damage the clothing I clip it on.  I kept the damaged one as a backup.

Price is great, however pin clips are not robust - they bend open after a couple uses leaving open circuits.

I got a couple of these for my MacBook Air computers, mostly so I could tell them apart.  They do a good job protecting the computers.  I'd like to see more colors available.  (It looks like they're working on that.)  But mainly, I wish the clips that hold it on were more durable.  One by one, they are snapping off, so I expect I'll have to replace the cases later this year.  I guess there is a warranty, but  get the feeling that it's going to be easier to just buy a new one than to make use of the warranty.

The clips will break off.  So don't try bending them and you will be fine.  The rubber stylus part is the best I have bought, none have broken off and I use them daily.

Great product , would recommend supplying bolts/ nuts to install, push clips won't last

They work perfectly on my 2 kindles--just wish the 'clip' didn't break off so easy.

I really like this product because it produces decent sound when playing music, phone calls are generally clear with no background noise interference and the battery lasts a long time. However, the clip broke within 11 months of purchase and that really bums me out. The plastic rings that held the clip in place fell apart. Overall I am happy with this device and in all fairness I am probably to blame for the clip falling off.

I have gone through several of these and material wear well but the clips keep on breaking.  Time to try something else.

I would not order again

For the price is it satisfactory, but I always buy two because I don't seem to get more than a couple months out of each one. The part where the clip attaches to the case will break off, it's just a matter of time.

These clips aren't the highest quality, but they get the job done - especially for only a couple bucks. I expect to lose a few clips whenever I get the oil changed, so these clips make up for that.

Perfect replacement for a busted clip. Clips are fairly sturdy but tend to wear out after around 6 months. Inexpensive to replace.

Great player, especially for running or working out. However, the clip mechanism is something to be desired. I have had this for about a year, and the plastic piece that connects the clip to the back of the player broke while clipping it on my shirt.  The sound quality is pretty good. I a minimalist runner so I don't like a lot of bulky equipment, armbands etc. This player fit the bill until the clip issue.

I have had to purchase a couple of these.  The clip breaks easily if it gets caught on something, like the seatbelt.  It is very cheap though, and  durable.

I've had this holster for just about 10 months and have loved it.  It fits the Droid Bionic well, either with or without the extended battery.  It's easy to insert and remove the phone.  And the headphone jack is easily accessible, which was a key point for me since I like to listen to music while working in a loud computer environment.

The problem is that the clip spring has broken.  I don't mind getting new accessories every once in a while, but I expect something like a holster to last at least as long as my phone contract.  Not even close on this one.  For the price, I'd expect it to last more than 10 months.
