Unlike with the Monster iFreeplay, the Shuffle isn't upside down, so the navigation buttons aren't reversed. Compared with the Monster product, Arriva's headphones are a lot more stealthy and don't make you look like a dork. Also, they're slightly easier to navigate blindly. It helps that with the Arriva headphones the Shuffle ends up sitting squarely in the middle of the back your head as opposed to living in the left earpiece on the side of your head.
As far as the sound goes, Arriva has managed to improve the sonics over its earlier model (at least when it comes to the in-ear 'buds). They may not sound great, but they sound fairly decent. So long as you don't expect too much and think more in terms of $20-$25 earbuds, you won't be disappointed. That said, the key to getting better sound (with the in-ear 'buds) is to make sure the buds are jammed into your ears snugly. The snugger the fit, the more bass you'll get. But if you lose that seal, the sound starts to thin out quite a bit. It should be noted that they play plenty loud.
Summing up, the Arriva iPod Shuffle headphones are a unique product that's tricky to review. You may be disappointed if you pick a model that you can't get to fit quite right. But if you do get the right one, you'll be rewarded with a set of sport headphones that will help you realize your dream of cutting the cord to your iPod. They may even make you want to buy a Shuffle just so you can use the headphones.Editors' Note: This review has been changed to correctly indicate that the Shuffle is not upside down when plugged into Arriva headphones.
