I gave this product two stars to acknowledge my appreciation for a great idea. After all, any product that eliminates a dangling cord at the gym has something going for it. Unfortunately, the execution didn't live up to the promise.
First, the sound is among the worst I've ever experienced from a set of headphones (even from the cheapest ones). The highs are muted. The mid-range is muddy. The bass is flaccid -- that is, I can sometimes tell it's flaccid when the right speaker doesn't happen to be buzzing loudly due to distortion. All in all, an abysmal listening experience.
Second, the product is simply cheaply made and feels incredibly flimsy in your hand. While my little orange Shuffle clicked into place with certainty, everything else about the phones feels like the company spared every expense. Am I nitpicking? I don't think so. When you pay 50 bucks for a set of headphones, you expect a level of quality commensurate with that price. But if you didn't know how much they cost, the iFreePlay phones feel and sound like headphones in the 12-dollar range.
Finally, I again want to say how much I like the idea behind these headphones. It was a pleasure to click my Shuffle into the little dock on the left earphone and go through a gym workout without a dangling cord catching on any of the equipment. And if the sonic quality these headphones produce was even merely competent, I'd be satisfied. But the sound is just unacceptable.
I feel bad because I know how even one negative review on Amazon can have a profound effect on the future of a product. And my review may severely retard sales of the iFreePlay. But Monster should have spent far more time in focus groups and quality control before releasing this product. They should also cut the price in half.
The bottom line: I'll wait for another company with higher standards to make a similar product. Or I'll wait for Monster to get its act together.
