Great for working out
Even with running, these earbuds don't fall out. The little part that sticks out and hooks into the outer part of your ear didn't bother me either. I do take an alcohol wipe to clean them because after working out, I can see the sweat all over them. This has not damaged the earbuds at all. Even the silicone hasn't cracked nor do I get black on the wipe from the silicone. The only issue I've had are a few people accidentally connecting their phones with my earbuds while its connected to mine. Other than that, great sound quality.

Quickly became my favorite earbuds
I'd say these are a great value for a few reasons. First, they are sturdy and have a little heft, but I can wear them all day and it isn't painful at the end like my old earbuds were. Then.. The sound. I wasn't expecting good sound I'll be honest.. But these have great deep Bas and get super loud. I wear them around sometimes with no music on because the noise canceling is so good and the microphone sounds clean for phone calls or using snapchat. I'm going to buy another pair for backups in case I lose these. They are that good, they feel and sound great and for like 18 dollars shipped its one of the better earbud values on Amazon.Edit: 4/22/2020 - I use these things like 5 hours a day.. and recharge every other day. That recharge to get 10 hours takes about an hour. I do not understand why these are so cheap? the sound is amazing and they are comfy, something most sub $30 earbuds are. I'm buying an extra pair just in case these get lost, i cant say enough good things about them!

Not the biggest fan but cheep is cheep. 2.9 rating for me out of 10
I am not a big fan of the sound.I own a lot of various Bluetooth headphones with that said the bass is fading when it hits and the left ear head phone on my set was not as loud as the right witch is a big issue with my set. There cheep and good for a back up but not your GO To set...

Cheap, descent sound, LOUD vocal commands - weird
Sound is great, battery life great and comfortable to wear (I wear glasses and can’t use the buds that hook over the ears). But every time I want to use with my iPad I have to forget and re-pair or there is skipping effect that goes on and on. AND there is a voice that tells you when the battery is low THREE times louder than what you are listening to - to the point of screaming in your ears that the battery is low. There is no other way to tell and no warning. I hate that the most. I could live with the re-pairing glitch each time but nearly having a heart attack when trying to relax is not fun.

Worth the great price with a few caveats
Music is clear but bass is not strong. I primarily use them to listen to podcasts and lectures, so light bass isn't a concern for me with these. Good price. I found these stay connected where the ones I replaced, even when newer, would crackle every 3-4 minutes, for about 3-5 seconds, like they were too far from the phone, even though I had my phone in my pocket.The issues for me are that the actual size are larger than others that I have used, which keeps you from being able to seat the ear tips far enough in the ear canal to feel that they are secure. They feel as if they will fall out. I added the pieces that are included to secure them better in the ear and they help. The buttons are beneath a rubber piece, so you have to "feel" around that piece before you figure out where the buttons are. Might just take a little time to get used to these. Lastly, when turning them on and connecting to my phone, I hear the audible "Powering on" and then a few seconds later "Connecting", and then almost 10 seconds to finally hear audio but with no confirmation that they connected.Still, for the price point, they are an inexpensive solution for me to listen to informational broadcasts.

exceeds expectations for price
If your looking for a sub $15 set of bluetooth earbuds, I would recommend these. I'm no audiophile, so I am sure these aren't actually the most fantastic sounding headphones, but I have been listening to podcasts and streaming music with them, as well as using them a ton for watching twitch streams on my roku while I do dishes, etc. These are pretty comfortable (with multiple size options you can swap to), and provide a very full sound. Battery life is excellent. No complaints, and for the price I would have been satisfied with a much cheaper sound.

Better than the competition
I bought these to replace Anker Sound Cores that I returned due to connectivity issues. These have comparable sound, were about $10 cheaper and also dont have the connectivity issues. Love them.
