Busy people like you and I don't have the time nor the inclination to navigate the sea of earbuds out there, so I turned to Wirecutter to find out what they recommended as the best earbuds. They've got a fine recommendation in the $100 category, and now that I've got a pair of them I can verify that they're great. Here's the executive summary as to why:
• Excellent sound, with a little extra bass.
• Flat cable shows you where twists are so they really never get tangled.
• Controls and microphone work with the iPhone and are unambiguous and easy to click.
One important note not on Wirecutter: get these memory foam tips with them. I tried the rubber inserts and molding my own earplugs (from two materials even!) but they always slip out or don't seal properly in my ear. With these foam tips you'll get a nice seal in your ear to project the sound, and they're practically earplugs on their own so you can't hear anything but the music even when it's quiet.
