Well, I searched and didn't return anything specific to my question. I've been using the ear buds the 4s came with.....and I don't dislike the sound. I'm actually happy with sound. I've been considering buying the upgraded Apple version with the different tips that seal the ear for fit. The OEM buds, just wont stay in my ear and they are uncomfortable after 20min. But not a slash on Apple, to me all hard tip buds are uncomfortable eventually. My slash if there were one would be the cords for Apple products are TOO short. Even the charger. But anyway, my dilemma is this. My wife loves the sound quality of the Apple mic. Others have also mentioned the difference when I call them now. When I called her from the car she flat out said that the phone had the best call quality of any of the 10 phones I've ever owned and called her from. I said well Im actually using ear buds. She couldnt tell the difference between when I switched in car to buds vs phone. So I myself tried it using buds vs BT ear bud and I could really tell a difference. Amazing. Not only are the Apple buds very very clear with perfect tone. Bud what I and my wife noticed was the lack of background noise that made the difference. WOW So, due to the short cord, I'm leaning at a 3rd party pair of buds......but can anyone here compare the mic quality vs Apple buds. I'm sure any of the 3rd party buds will have sound quality as good or better than Apple, but its the mic/call quality I'm concerned with. I dont know if the awesomeness comes from the actual Apple mic or the phone doing the magic.....BUT I WANNA KEEP IT.
