Fitness junkies can finally get their active groove on without hassle.  A wireless, small, bluetooth headphone that actually stays put during almost any fitness routine has finally entered the market.  The iSport Super Slim Wireless Bluetooth In Ear Headphone (wow, that’s a mouthful) was recently introduced by Monster – one of the top audio companies.  Having revolutionized connectivity in all forms, Monster has already made the world sound better and look better.  Today Monster is the largest manufacturer of headphones in the world.  Their innovation continues to impress with each and every new product, including these impressive little things.

isportMonster was founded 35 years ago by Mr. Noel Lee.  Lee, who worked as a laser-fusion design engineer, was also an audiophile and professional drummer.  With that combination of talent and passion, no wonder why their products are touted so highly.

The iSport Super Slim was designed to be a fitness headphone, but can definitely be used in other occasions as well.  Monster took many situations into consideration when developing this headphone.  From size and functionality all the way down to the microbial water resistant in-ear tips.  I like to do a variety of activities, so I wanted to make sure I put these headphones through multiple scenarios including running, weightlifting, biking and even yoga.  These little headphones never failed me.  The slim stream-lined design and water resistant ear tips make these headphones the go to choice.

Key Features:

  • Small slim design
  • Lightweight
  • Wireless/Bluetooth
  • Water resistant ear tips
  • 5 hour battery
  • 50 foot range
iSport SuperSlim Review Breakdown


The iSport Super Slim offer the clarity, dynamics, punch and power of Pure Monster Sound.  Unlike their previous model, the basic iSport Bluetooth Wireless Headphone, Monster’s new Super Slim design lets you wear goggles, helmets, beanies and other head gear all while maintaining that comfort you want.  The multiple sizes of in-ear tips (provided) are water resistant, so even during my sweatiest routine the Super Slims didn’t budge.  The new raised central button made adjusting the volume and transitioning between tracks hassle free.  Although the earbuds are not labeled as noise canceling, you’ll notice a dramatic decrease in exterior sound as soon as you put them on.  The snug fit and design of the in-ear tips not only provided the comfort I was looking for, but added another level of intuitive design that helped enhance the sound of the music while keeping the exterior ambient sound to a minimum.

I must confess that I am super picky when it comes to headphones.  More often than not I will just go without because I find them uncomfortable and irritating or they just don’t stay put.  I like a headphone that will allow me to focus solely on the activity that I am doing.  The iSport Super Slims are so lightweight that you almost forget about them.  The included in-ear tips deliver a comfortable snug fit for most any ear.  One of the best things about them is that I am able to wear my bike helmet and sunglasses, or even my snowboarding helmet and goggles with no problems.

Audio Quality:

The sound quality is exceptional.  With any earbud you would expect a loss in the bass, but these produce just the right amount to compliment the mids and highs of all your music.  The snug fit also helps enhance the audio by keeping exterior sounds out.  Plus, there’s no loss in quality the louder you go.



It may be difficult to fork out $150 for some headphones, but these aren’t typical headphones.  The Monster iSport Super Slim give you that freedom from wires you’ve been wanting.  Comfort and incredible audio all packed into these slim and sleek headphones make the price tag worth it.  When you compare these to other wireless headphones on the market, for the quality and convenience, these things are actually a really good deal.  What it really comes down to, is having comfortable headphones with excellent sound and no wires.  The iSport Super Slims deliver on all accounts.

      In a nutshell, most of the tech specs are the same. The wireless range for the Super Slim is further though. Fifty feet compared the 30 ft (I believe) for the regular isport wireless. The Super Slim lay flat with your ear so you can comfortably wear hats and helmets. The cords a slightly different, and so are the control buttons. Besides those few things, they are similar in the other aspects. The comfort of the slimness really makes a big difference though, in my opinion.

        First off, thanks for responding! Second, I have now seen on a couple websites/blogs that the Super Slim;s range is 50 feet compared to the standard 30 feet, but even the monster website lists the Super Slim at 30 feet. Where are people getting the 50 feet from? Also, if i don’t plan on wearing them with hats or helmets ( I just use mine to weight lift and/or shoot hoops) is the extra $50 worth it just to have them more slim? Or would you think the audio quality is better?

    The 50 foot range came from their original release info. It seems that they may have changed that now on their website. If you don’t need slim headphones, then the original isport would be just fine for you. I haven’t personally used Monster’s original isport headphones, so I can’t do a true comparison. I’ve only used other brands for comparison. The super slims do a really good job drowning out background noise around you. If the ear piece is identical (as it looks to be) then the originals most likely do the same. You may feel that the wire/band on the super slim sticks to damp skin more though. But everybody feels differently about this. The way I see it, if you can handle the extra $50, then go for it (but pay attention to return policies incase you discover they aren’t for you). You never know when you may need (or want) to wear them under hats or helmets. I realize I probably didn’t help you at all with your decision! Haha!
