These are awesome!
I don’t do many reviews, but these are great earbuds! I only bought them out of necessity at the time and thought I’d buy a better pair later. However, I bought these almost two years ago. They are still going strong. They are comfortable and I love them! I use them almost everyday and sometimes all throughout the day. I only have to charge the case maybe once a week if that. Battery life is awesome. Good sound, decent range. No issues with clarity when using them on phone calls. Great value for the price.

Glad I bought these
THINGS I LIKE ABOUT THESE EARBUDS: The price is great. I I like the color of these earbuds. I like the over-the-ear piece, it is flexible and comfortable for hours of use, and I never have to worry about them falling out. Also, with the over-the-ear piece, I don't have to press the earbud itself into my ear very far, also increasing the comfort. I've worn these for 8 -10 hours at a time with only occasional, minimal discomfort that was eased by just shifting the position of the earbuds slightly. The battery life is phenomenal! I've often been amazed that when it announces it needs charging it's been playing for 8 hours. It also takes a long time before I need to recharge the case. I like that I can use just one earbud at a time. It also works fine with my Google Assistant. I can walk farther away from the audio source than I can with my Galaxy Buds Live. ONLY THING I DON'T LIKE AS MUCH: The sound on these is only acceptable -not great. The volume can go high, but I keep it at a moderate to low level because at anything more than that the sound seems tinny or brassy. At first the sound didn't seem very good to me even at moderate levels, but I've gotten used to it and now to me it sounds fine, especially for podcasts and audiobooks & phone calls. I mostly use them for voice audio, and they seem fine for that. I don't listen to music as often, but at medium to lower volume levels I now feel the music also sounds alright. It just doesn't have great sound like my Samsung Buds Live do. I can't imagine that any earbuds in this price range would have any better sound. CONCLUSION: Overall, I'm very glad I purchased these! I use them almost every day, and for my everyday use, I like them much better than my Samsung Buds Live which can fall out of my ears. These will never fall out of my ears, so they're great for when I'm moving around, doing my everyday tasks & great for exercising.

Stable fit and sound
Fantastic ear buds. Love them more than my giant nose ones. Great sound, don’t fall out, and cancels noise well.

Very durable and great fitting
THE BEST. These hold a charge for a long time, they’re super easy to use, the sound is great, and they fit very well. I always struggle finding earbuds that stay in my ears and these never fall out. My husband purchased his well over a year ago and uses them 5+ days a week and they’re still like new. I’ve had mine for several months and they’ve held up great.

Nice but No
They worked well for a year then one of the ears went out. First they were everything. The over the ear was comfortable, sound quality good, and while on walks, I could hear the outside noise. However, I could still hear my podcast or music very well. The charge would last a full days work. From 9-4, I used them daily, then suddenly the charge only lasted maybe 4 hours so I had to give them up and buy a new pair.

Great Product for your money....
I purchased these earbuds for Christmas for my husband. He enjoys listening to music while doing yardwork and mowing the lawn. They fit great into his ears and he has not lost the signal. The rechargeable case is very good. The quality is very good, I'm going to purchase myself a pair!!
