iFrogz C240 Iron Headphones Review

http://ifrogz.com/image/master/EP-CS40_ep-cs40-gmt.png_50_xThere are two things that matter most, more than anything, when it comes to headphones: comfort, and sound quality. iFrogz has done just that with the cs40’s. I have already reviewed these headphones and now the option of new designs and styles make the supplementary features like customizability and aesthetics have been covered as well. Not only are these one of my favorite pairs of headphones but they are also one of the best headphones I have ever seen for cost to performance ratio. I have reviewed a lot of headphones, so read on and see why these headphones take the cake as far as I am concerned for headphones under $50:

My overall thoughts haven’t changed much in the months since reviewing the first iteration of the cs40’s they are still incredible sounding and well make headphones. The bass , while not as good as the moguls or Ronins, is still better than any other headphones I have tried in its price and size category. The sound quality over all is even more impressive, everything is well balanced and rings very clearly without muddy bass or sibilant treble.

Would I recommend this product? Yes, it is well made well priced and has great customizability.

  • Multiple Color Choices
