Being able to take and play music on-the-go isn't as practical as we all hope it would be. There are plenty of portable music systems out there, but most require power or some sort of extravagant rechargeable battery system.
Without having to revert to using a smartphone's speaker (gasp!), iLuv has provided a practical, discreet, and ultraportable way to play music on the go. The iSP110 won't wake up the neighbors, but for scenarios that won't allow for any other bulky or powered alternatives, it does the trick.
Not too much bigger than a sunglasses case, the iSP110 comes in a variety of colors. On its outside lays a clip for attaching to anything from a belt buckle to a golf bag, and a tethered zipper keeps the case shut and your music player protected from the elements.
Inside is a compartment for two AA batteries (not included) and an on/off power switch. In the adjacent pouch is a fishnet sleeve that can hold most small media player devices. We were able to cram our hefty HTC Evo 4G along with an extended battery snugly into the pouch. That's about the biggest item that can fit, so be sure to take note before a purchase.
A 6.5-inch 1/8-inch headphone wire protrudes from the speaker side of the case. While it's enough slack for an item tucked inside the speaker case, it might be tough attaching it to a larger device. Of course the iSP110 is focused on mobility, so that probably won't be much of an issue, but having more slack is never a bad thing.
