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
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.

Holds a great charge . Solid 10 out of 10.
I’m very impressed with this one. I would recommend this to anyone. It does great noise cancellation a fantastic value for the money. The sound quality is great. The mic works very well. People talk on the phone and they say they can hear me with no problem and I can hear them very clear very comfortable to wear and what impressed me the most : it holds a charge so well , i’ve left them in my bag for two weeks at a time and they’re still charged, the attached photo shows they’re still at 100% and they were charged at least a month ago!! much better than even my Apple pods. I’ve purchased four of these now for myself and grandkids..

Love this
These wireless earbuds have become my go to. I love that I only need one at a time and can flip back in forth from one ear to the other extending the battery life. They are also super durable. This is my second set. I bought the first ones over a year ago and I am only replacing them becuase I misplaced the right side. I have never had a issue with sound quality. They fit perfectly in my ear and are easily adjustable. I have loved using these for yard work working out and several other activitys.

Decent For What They Are
I really enjoy using these earbuds, but they do have two flaws which is the reason the reason I only gave 3 stars. They are entirely too sensitive to the touch when I don't need them to be. I use to use them for my gym workouts, but I had to stop due to their sensitivity. Let me explain. When I workout I normally wear hoodies. And these earbuds would engage the pause function if the hoodie touched them. Not to mention if I tried to do any over the head stretches such as triceps stretch with my right hand holding my elbow back over my head or vice versa, it would engage as well. The second issue is that they are too difficult to take out of the case. The design doesn't allow for any type of gripping of the earbuds out the case in order to remove them smoothly. There is a space in the case that you think would allow for them to be taken out easily, but such is not the case. Other than those two issues, these earbuds are okay. I use them with my laptop at home since they are pretty good sound wise.

Amazing earbuds.
These are the only headphones that work for me. I have tiny ears so I got so lucky when I ordered this product. The charge last me about 4-5 days at a time using them almost non stop. They are very lightweight in the case and when I wear them it doesn’t even feel like I’m wearing anything. The volume is great. I don’t even have to have the volume up halfway because the volume is loud enough for me. The buttons are easy. And they are great quality. I’m very rough with my head phones and they are still going strong. Highly highly recommend this product.

good earbuds for sound and noise cancellation
Comfort is a priority, with an ergonomic design and customizable ear tips providing a secure fit. They stay in place during workouts, thanks to the included ear hooks. The Hi-Fi Stereo sound quality is exceptional, delivering a rich and balanced audio experience across genres. The built-in HD Mic with noise-canceling technology ensures crystal-clear calls, even in noisy environments.

Se adaptan estupendamente
Tienen una conexión más estable, menor latencia y menor consumo de energía. La calidad de sonido estéreo de alta fidelidad es buena, con reducción de ruido para llamadas más claras. La base de carga magnética y la pantalla de potencia precisa son características muy convenientes. Además, la duración de la batería es larga y la carga rápida por lo que los puedo usar sin preocupaciones. El emparejamiento automático es rápido y el control táctil hacen que su uso sea aún más sencillo. La pantalla digital que indica el nivel de carga de los auriculares es realmente útil y práctica. Me encanta la funda de carga cómo muestra con precisión la potencia restante de los auriculares. Así, siempre sabes cuánta energía tienes disponible y puedes cargarlos a tiempo sin preocupaciones. ¡Una característica realmente conveniente que hace que los auriculares sean aún más impresionantes! Sobre el precio: el precio asequible los convierte en una opción atractiva para cualquier persona que busque una experiencia auditiva excepcional sin romper el presupuesto. ¡Una excelente relación calidad-precio para unos auriculares inalámbricos con todas estas prestaciones! ¡Definitivamente, una excelente elección en auriculares inalámbricos!.
