Although the iSport Victory don’t sit quite as flush against your ears as the iSport SuperSlim, they don’t protrude enough to make them feel like they’ll fall out at any moment. Even after building up a sweat, the headphones continued to feel secure in my ears. Monster iSport Victory – Sound and call quality The problem with suggesting an alternative is that there simply aren’t any really great on-ear headphones that can offer the kind of features the Freedoms can. If you are happy to go in-ear there are definitely some great options like the Pioneer SE-E721 or the Sennheiser PMX-685i, which do have a headband-style design. If you are willing to spend big, then the Monster iSport Victory in-ears do a much better job than Monster’s on-ears. Verdict

The company estimates battery life to be roughly eight hours, but your results will vary with your volume levels. Aside from the ear fins and tips, Monster includes a small drawstring pouch for the earphones, and a micro USB charging cable that connects to a covered port on the inline compartment. Performance Featuring Bluetooth technology, these headphones offer a seamless and stable connection to compatible devices. The wireless range allows users to move freely within a certain distance from the device without losing audio quality. These are made from supple silicone and I found them super-comfortable, even when worn for prolonged periods. You get a choice of three wingtip and five silicone tip sizes in the box, which means you should easily be able to find your perfect fit. We were big fans of the iSport Victory, and with the addition of Bluetooth connectivity, the iSport SuperSlim will be even more of a runner or gym lover’s best friend. We love the washable, secure design and can live without the finesse in the sound quality for what is, overall, a great sounding pair of sports headphones.

If you’re more heavy house than audiobook enthusiast, then you’ll love them. It’s all about the bass, but it isn’t delivered in the erratic way of other wireless sports headphones – such as the Beats PowerBeats.

Bluetooth wireless is the main concern with the Monster iSport Spirit, and not in the usual manner. Once they’re settled in, performance is perfectly good, with just a momentary blip or two for every handful of hours of listening. Bass is big and punchy, if quite poorly controlled when you stop for a moment and listen with your critical head screwed on. There’s some boominess in songs with strong bass, but it doesn’t leave the iSport Spirit sounding muggy or dominated by bass. There’s real energy in the treble to counteract this. The cable is surprisingly thin and doesn’t weigh very much as a result, making it less noticeable. It’s also pretty flexible, managing to deal well with the rigours of having the headphones thrown casually in my gym bag without any extra protection. A small travel pouch is included, but I didn’t find a need for it. However, if you want to chance it, and buy from a retailer that won’t make a fuss if you try to return them if they fail to work properly with your phone, they’re worth a shot. For runners and gym fans, at any rate.As a pair of sporty on-ear headphones there’s plenty to like about the Monster iSport Freedom. The surprisingly lightweight design make them perfect for the gym and the bright, reflective exterior is great for running at night. It manages a faultless Bluetooth performance and the water-resistance is a real bonus especially if you get a real sweat on.
