The earbuds that came with my iPhone were okay, and if it wasn't for them blocking out other sounds I might still be using them. After some experimenting I settled on Plantronics Backbeat Fit Bluetooth earphones. Good sound, great battery life, waterproof, phone answering, and very important to me, they do not block ambient sounds. I can hear my music, podcasts, radio and still hear the tire noise of that approaching car well before I see its headlights.
