Bright, peppy audio
Setting up the SuperSlims is easy. To turn them on, just press and hold the middle button on the remote. To pair them with your device, press and hold that middle button a bit longer, and then search for "iSport Wireless Superslim" on your device's Bluetooth list. After you pair them once, they should stay paired the next time you turn them on within Bluetooth range.
The SuperSlims are wireless, which means they have a battery, which is recharged through a small, covered slot on the front of the right earbud. Battery life isn't great for Bluetooth headphones — just over five hours, according to Monster — but I don't know many people who work out for five hours at a time. These earbuds should last you through a couple of workouts before you need to recharge.
The SuperSlims' audio performance isn't great: Mid-range frequency response is pretty good, but they're very bright at the high end. Bass response isn't as impressive, but at least it avoids being muddy. I'm really into bass and EDM, and these earbuds founder with that style of music; but if you lean more toward the peppy vocals of Katy Perry tracks during your workouts, you might have a different opinion.
Should you break out your plastic?
Monster's iSport SuperSlim wireless earbuds aren't for everyone, but they will appeal to a certain audience. Some people like to overdo the treble as much as I like to overdo the bass, and these headphones are them. While they're a little tricky to put on, they are slim enough to wear under a helmet, so they're a good choice for cyclists, too.
