---TIP for using the touch controls---The circular part on the outside near the speaker end is the only part that's touch-sensitive. It's tricky to use if you don't understand it, but it's actually really easy to handle:1) Touch the end of the earbud that's pointing out away from your ear.2) Keeping your finger on the earbud, trace your finger up until you feel the circular touch-sensitive area (circled in yellow in the second photo). The touch control won't activate immediately when your finger moves over it.3) Once you've found the button with your finger, you can tap/double tap/triple tap/tap and hold, according to the instructions in the manualReview:I like these a lot! I was really reluctant to get a phone without a 3.5mm audio jack, but these earbuds are great and easy to deal with.Pros:-Exceptional battery life. If you use them intermittently like I do and put them in the little charging case when not in use, the batteries last at least 3 or 4 days. I have to charge them way less often than I charge my phone. This was the biggest selling point for me.-I got them for around $50, which is a pretty good price for wireless earbuds.-Very easy to set up and use.-The sound playback quality is good.-The microphone quality is decent for an earbud mic. It sounds really tinny, but my voice is very intelligible, which is a big upgrade from the built-in microphone on my old phone.-You can use only one of them if you just want sound in one ear, and leave the other in the case.-The charging case is big enough that I don't feel like I'll lose it too easily, but small enough to fit in my pocket. The earbud snaps into position with magnets, so putting them into the case and taking them out again is really effortless.-They feel pretty comfortable in my ears. I'm used to using the $5 wired earbuds you would find at like Staples. These are noticeably heavier, but not too bad.-You can pair them with more than one device at the same time. They'll play sound from whichever one is currently playing.Cons:-If I lean forward at a steep angle, they sometimes feel like they're going to fall out. This happens more in my left ear, which probably means I need to use a smaller size foam thing (it comes with four sizes; I think I'm using the second smallest size). It would be nice if they looped over top of my ear or something to keep them from coming out.-Occasionally when adjusting them I'll hit the touch control button by accident.-You have to get used to the touch controls, as I mentioned up above, but it really only took me 5 or 10 minutes to get the hang of it.Other:I haven't put their water resistance to the test (and I don't really plan to, if I can help it).The Android app requires your location (which seems completely unnecessary), but it gives you extra options, like you can change what the different tap sequences do. This might be good if you want to use only one of them in one ear, and you want to be able to adjust the volume either up or down on the same earbud. The app can also make the earbuds play a loud sound to help you find them if you lose them.You can't really use the app without the location permission. You can still use the earbuds without the app, though, if you prefer.
