The Monster iSport SuperSlim are the company’s second pair of Bluetooth, wireless in-ear headphones firmly aimed at sporty folk. Building on the impressive wired iSport Victory earphones, Monster is promising the same powerful, bassy sound in a design that is built to withstand your sweatiest workouts.

Sound Quality

Monster’s typically deep sound is not going to be for everyone, but the company delivers some of the best-sounding sports headphones out there. If you are more heavy house than audio book enthusiast, then you will love them. It is all about the bass, but it is not delivered in the erratic way of other wireless sports headphones, such as the Beats PowerBeats. While it is not needfully safe if you are cycling or around busy roads, if you are the kind of person who likes to block out the world, then the iSport SuperSlim will not let down.

Specialties

A significant specialty of the iSport SuperSlim are that they are wireless. You get six hours of wireless playback with a 50ft range before losing connection. This should be enough to move from one gym machines to another when it becomes free. It is a Bluetooth connection, which is activated by pressing the central button on the remote. The logo will light up blue if there’s enough battery, or flash red if it needs a charge. Thankfully, if you’re away from a connection then it will shut itself down, helping to preserve that precious battery life.

Style

The first big change is with the iOS-friendly ControlTalk mic. It can still be used for skipping tracks and adjusting volume, but the design is more robust. The buds themselves are larger, however, to accommodate the built-in battery and the USB charging port. Monster says these are its slimmest in-ears, but line them up against the Jabra Pulse and that slight slenderness is not something to make a song and dance about.
