I tried the B&O I had gotten with the LG promotion because I wanted to make sure there wasn't anything wrong with the phone. Wow it's like night and day. Less tinniness and more bass.
Re: The B&O Headphones are so much better than the AKG
$99 doesn't seem like a realistic retail value. The included AKG branded headphones are apparently just Samsung headphones tuned by AKG. More comparable to $30 headphones. At least they sound better than earpods.
