Review: Amazing Sound and Comfortable Fit - “These earbuds exceeded my expectations. The sound quality is clear, the Bluetooth connection is fast and stable, and they are very comfortable to wear for long periods. The battery life is impressive, and the charging case is compact and convenient. Great value for the price!”
Review: A Very Functional Wireless Sports Earbuds - I have been using the Ltinist BX27 Sports wireless earbuds for a little over a month. The earbuds are of high quality, waterproof and suited for almost any sports activities. I have showered with these earbuds on and experienced no issues. The flexible lime green ear wrap is sporty and comfortable to wear. The wrap around the ears design keeps the earbuds securely in place even during intense physical activities. The battery life is impressive. I have not been able to deplete the battery in one continuous session. So far, I have only charged the BX27 3 times, not because it ran out juice but just to top up the charge. The sound quality is excellent and the price is very affordable. I used it mainly for listening to the news and background music. Voice calls over the wireless earbuds are clear and I have never experienced any drop offs. For the price, I would certainly recommend these earbuds to anyone looking for a reliable and economical BT wireless sports earbuds.

### ⭐⭐⭐⭐ Glad I bought these
*by A***A on August 10, 2023*

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.
