The triangular rubber that holds the bud onto the inset of the earlobe started breaking after a little over a year

It somehow overcame that and the battery works fine, but the bigger issue is that the material started to expand and all the rubber linings and plastic covers are falling off, including buttons

However if you are already on a call, it interrupts the ongoing call and starts reading out the number in case another call comes through

I didn't mind at first, but now several of the buttons are difficult to operate because their plastic button coverings have started peeling off.

Then the product started falling apart.

But the rubber casing started falling apart after 6 months of using

Loved it unconditionally until the outer rubber shell started peeling off one of the ear pieces

I was wrong until I've started using these

They lasted about 3 months, and then during one of my normal runs, while sweating, static started and the headphone shut down.

Then 2 months later they started to fall apart, pieces started to come loose and eventually fell off

... merry x más to YOU

n’t get a static humming at some point while talking on the phone.

n’t had any problem at all, they haven’t gotten out of my ears for a single time, one advice though if you don’t use your nails when you push the buttons, they won’t get deformed

n’t slip off my ears like my over-ear sports ones I had before did

n’t work

n’t recommend if u sweat a lot when u work out ...

n’t feel good.

n’t lose signal

n’t work well with any sort of ear

n’t fall apart again.

n’t recommend these and that makes me wonder what happened at Bose.

There is significant delay in the audio making watching video distracting as it is not synced.

The buttons are a little mushy, but thats fine with me as long as they work, and they did.

These are comfortable, don't fall out of my ears, the sound is outstanding both for my music and phone calls (as well as for the people on the other end of the call)

I like headphones always look for something that meets my demands, and buy this Bose sound sport, I recommend the sound is spectacular, smooth as if you were in a movie theater, I give it 5 stars

The sound quality is rich and they’re perfect for his workouts at the gym as well as for his marathon training runs

If for instance you try to run with them, prepare to continually fidget with them as you try to keep them jammed in your ears.

They occasionally lose connection with my phone (not often, but annoying just the same) and the heart rate monitor doesn't work as consistently as I would like.

I ran for 30 mins and they died as I was stretching.

The battery life did disappoint me at first as it couldn't last as

I was really excited to replace my previously stolen headphones with this nearly wireless pair, I run in the gym every day as well as

I love R&B, Pop and Classical music and these headphones really brought the music alive.
