I know these go on sale periodically, but I haven't seen the price drop this low recently for the second generation. First gens can be had for this cheap, but the sound, battery, and dustproofing are all supposed to be better in gen 2. The Ultimate Ears website has a comparison chart for those looking to see the differences: https://www.ultimateears.com/en-u...oom-2.html
Couldn't get BB to price match in case anyone is wondering.
