Man I wouldn't go back to straight headphones. It's not like I'm going to get good audio quality on the bike anyway. With straight headphones on a phone I've got to be concerned with getting the thing wet. Even sweat I've had drip down into MP3 players and destroy them over time.

Also, no matter how I tried routing cables, occasionally it'd fall down into a loop and I'd catch it when reaching to wipe sweat off my face or something, and my MP3 player would go flying out of a pocket and skid down the road. Sure wouldn't want that to happen with my phone.

Gimme bluetooth anytime. I put the phone in the waterproof rack trunk and don't worry about it.

The batteries on my new phone last almost 2 full days even when using it with bluetooth and accelerated podcast/audiobook playback heavily all day. Accelerating the speed draws WAY WAY more power than bluetooth does. The most I've managed to get my batteries down in a day is about 47% by bedtime, if I use bluetooth all day long.
