I hope someone will be doing a frequency graph of the AirPods soon then we can have a objective assessment of the sound.
As for sound quality, I think it's competitive among earbuds/IEMs of the same price.
The soundstage is wide, wider than your typical IEMs because of its open earbuds design.
The sound signature is neutral with some emphasis on mid bass. It seems to be lacking in sub bass, which is not unexpected since it's a earbud.
The biggest selling point to me is the convenience.
Like I have never bothered to use a portable amplifier away from home because the gain in audio quality is not justified by the increase in inconvenience.
With the AirPods, you don't have to worry about inconvenience like wires or battery life.
Just pop them out of the charging case and they reconnect in an instant. Battery life is taken care of while they are in case. I can charge the case with the same cable I use to charge my iPhone.
If they run out of battery (5hour battery life), I just put them back into the case for 15mins and they will be about 50-60% charged.
The convenience of wireless and worryfree battery charging.
I definitely will not buy a wireless set which I have to plug in all the time to charge them.
For the combination of price, convenience and quality, I have no complains. It's *only* $159 with a lightning cable, quite the bargain in the audiophile world.
It seems like many people buying AirPods haven't listened to the EarPods. $159 is a good value for truly wireless earbuds, but if it's simply the wireless version of $29 earbuds the value isn't as good relatively. I'm not looking to be blown away by its sound, but I'd want some improvements in that regard for the $130 premium.
