If you love listening to music while you're working out, regular earphones can give you a good deal of trouble. They'll fall out of your ears, their cable gets in your way, and to make matters worse they often can't cope with a bit of sweat. Fortunately, SMS Audio offers a great alternative with the Sync by 50 In-Ear Wireless Sport (Blue) in-ear headphones, which have a moisture-resistant coating. Stay-Fit Wings and ear tips - both included in three different sizes - keep these blue earphones securely lodged inside your ears. Thanks to their Bluetooth functionality, you won't need a cable to connect them to your smartphone. The short cable that connects the two earbuds is equipped with a slim inline remote with a mic, which means taking calls, adjusting the volume and pausing or skipping tracks is no problem.
In-Ear Wireless Sport Blue: Bluetooth, remote and battery
The In-Ear Wireless Sport earphones receive their power from a built-in battery. Once it's fully charged - this takes about two to three hours - you're able to listen to your music (or make phone calls) for approximately eight hours. Recharging the battery is easy: simply connect the micro-USB connector behind the cover of the left earbud to your laptop or USB power adapter, using the included USB cable. The earphones come with a stylish pouch, so you have a safe place to keep them when you're not using them.
