Review on 🎧 Otium Audio Wireless Sports Earbuds: Waterproof IPX7, HD Stereo, Bluetooth Headphones with Mic, Fast Pairing - Ideal for Gym Running Workout, 7-9 Hrs Battery Life, Noise Cancelling Headsets by Will Lockhart

I really like these headphones. The sound quality and materials are really good. They're comfortable and stay in place (I do HIT and they've never fallen out of my ears). The battery life is very good, I use them 1-2 hours a day and they last 5-7 days on a single charge. However, you only have about 15 minutes to use it once you get a low battery message. Since my battery is dead, I charge them for 5-1 hours every day before training. They have an LED that lights up when they are in use (they are on or charging) and changes color when, for example, charging is complete. They only have one input, and it's for a micro USB charger, you can't connect an extra cable or other cable to them. They are water and sweat resistant which means you can work out with them, use them in the rain or in the shower, but it is NOT recommended to use them for diving or swimming. They also have a built in microphone which works perfectly, I was afraid it wouldn't sound good since it's so far from my mouth but I never had a problem speaking with it. You have three buttons: one for power on and off and two for volume. In fact, you can use them to answer calls, skip songs, play/pause videos, etc. They're handy to have on hand, so I'd recommend them for any headphone needs (except for swimming, of course).
