    • A Very Functional Wireless Sports Earbuds
Size: 800 mAh Color: green-black
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. ... show more

    • So much better than expected
Size: 800 mAh Color: Rose Gold
I bought these because my new phone didn't have a headphone port, so this my first set of wireless earbuds. They are amazing! They far exceed my expectations. They paired quickly and easily, the first time and every time. A single charge lasts for a very long time - months, with almost daily use. They are comfortable and the sound quality is great. They work well for calls. The people who I'm talking to say they can hear me great. I'm very pleased with this purchase. ... show more

    • Comfortable
Size: 800 mAh Color: Rose Gold
For what these cost, I was skeptical at first on the comfort and quality of these since they were on the cheap side. But they are actually great. You can hear out of them pretty well and it's a smooth transition over from music to phone-they pretty versatile. Performance wise I use them daily and they hold a charge for at least 5 hours before it gives you a warning of battery low. They are durable for work and don't fall out, perfect fit for my ears. And you really don't notice them while you're wearing them, I do love the rose pink color. ... show more

    • Great for small ears and comfortable
I have always had issue with ear buds staying in my ears as I have very small ones. I saw these and had to try them. The first thing I noticed is they came fully charged which was a plus. They come with two extra ear covers to change out. I used the extra small ones. They fit perfectly inside my ears. The ear piece itself is a soft rubber that goes around your ear. Once0laced inside your ear and attached around your ear, it never moved the whole time it was on my ears. I couldn't even tell they were one. They are super comfortable, they didn't hurt my ears at all. They aren't flimsy and they have a durable case to put them in wheen you are done for them to charge in. The sound quality is great for music, voices are clear when you receive a call. It took me a few times to get used to the functions on the ear piece itself and a few call hang ups and a slight learning curve but once I got the hang of it they were great. Overall one of the best Bluetooth ear pieces I've tried so far. They told have static during calls or playing music. Directions are easy to follow and they have a USB cord to charge to case that you put them in to charge. Would definitely recommend. ... show more

    • Decent For What They Are
Size: 800 mAh Color: Dark Blue
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. ... show more

Size: 800 mAh Color: Rose Gold
They were definitely worth it, I bought the ones that don't clasp on your ear and they sucked I legit lost both the buds...But with these I have NOT had that problem yet.! I am very impressed with their battery life so far... I honestly haven't really had to charge them yet.! I love how the case actually charges the earbuds themselves which is a plus! The sound quality it awesome. I have used them for a call twice so far and I haven't had anyone tell me they cannot hear me at all so that is also a big plus! ...So Far, So Good... ... show more
