Pros:*They're cheap, cheerful, and do the job.*Ear bud covers are easy to replace, other misc brands seem to sit just fine.Cons:*They're a strange mix of wired bluetooth, they need to pair/"connect", it's not mentioned in the listing.*They don't work with splitting cables. I tried them with a cable that let's you use headphones whilst charging. The iPhone will say that the device isn't supported. I bought a second hand pair of the official apple earphones, they don't need to pair with the device and they work with splitter cables. Just a pre-warning for those who may need to charge whilst listening to something.*The music control buttons are very finicky. It was frustrating trying to use the controls to skip backwards through songs and sometimes you'd get blasted by high volume, sometimes it only registers two presses instead of 3. I thought this was down to the app i was using, but no, since using the official earbuds i can now rule this out. It's possibly due to how they connect (quasi bluetooth) but i can't be sure without also trying wireless/other bluetooth earphones. It's just something to keep in mind if you're an avid music "looper" or someone who relies on the controls a lot for pausing/play etc.
