Document: I have had two similar models from Philips now. They serve the purpose of staying on during running or exercise. Music quality is better than in previous model. However, the earlier one stopped working after 9 months, and philips sent me a check for the price since they did not have replacements.
i have been using philips in-ear phones for years now.. the last one was the older version of this one and it lasted for two years...so when this went up on sale last year, i bought two!.....the first one lasted only 4 months. the second one just a month!!!!! !not really sure if i was given two defective products.. :(
On a few occasions, I've had to sort of reposition the angle of the hook, which had slid one way or another. This was due to the fact that I am the sweatiest guy in the gym by a factor of ten, and a little lubrication with these things can go a long way. (Okay ladies, take a breath.) If when you run you don't leave Lake Superior on the treadmill, this will not be a major issue for you.
It loses the audio output quickly... I mean, you need to start increasing the volume to be able to hear. I nthe first set it was more gradual, but noticeable after 1 year.For the last set the issue appeared after 2 months in one side so I now have a monaural headset.Regarding warranties: it says Philips covers one year, but good luck with that.
Great for running! Very light and thin. However, I'm not sure you want these for high quality sound and definition while listening to your favorite music.
These headphones sound fine, but they don't seem to want to stay in my ears. I've used the largest tips provided and they just seem to pop out. The other really annoying thing is the wire is very short -- several inches shorter than other headphones. This makes it difficult if I want to have my device in a pocket or on a belt clip since the cord won't reach.
Similar to others, I like to listen to music while running (~4 to 6 miles). I have two primary criteria for headphones/earbuds: 1) they need to stay in place, and 2) they need to sound good enough. * Staying in place: 4 starsI have no complaints regarding these earbuds moving around or slipping out.
These earbuds don't sound like my Bowers & Wilkins floor standing speakers but for $18 I wouldn't expect them to. On the other hand, I wouldn't sweat all over my B&W speakers and then douse them in water to clean them and expect them to still function. These earbuds do just that. I purchased a pair two years ago specifically to wear when exercising that worked just fine and so I purchased a new replacement pair when the originals wore out. These really are waterproof and they're comfortable.
I bought these ear buds because I cannot stand the ones that Apple sends out with their products. I like the earhook design as well as the interchangeable sized pieces that you receive so that everyone can get a snug fit. The sound is not as high quality as I would like, but is solid for ear buds that are used almost exclusively for running and working out.I do have two big complaints about these:- If they get ripped off your ears because the cord gets snagged on something; it hurts.
The cable/cord is a bit too short.I use these things on an MP3 player (Sansa or my S4), when I bike wearing a 3-pocket biker jersey. If I do not move my head too much, everything is fine. If I do move my head, the cord yangs on my ears and feels like (though it never has) will fall out.
Answer: This headset doesn't have any functioning buttons.  The "Y" between the two ear sets is just that - a split. Unless the version you're looking at is a latter model than mine.  Mine doesn't have any functioning buttons.
