There may have been some big changes at Beats recently, but it's still all about the headphones. The newest addition to the (ever growing) family is the Powerbeats². As the name suggests, they are a revision of the original sport-friendly buds from Beats, but this time they're wireless -- Beats' first in-ears to cut the cord.
The Powerbeats² keep the (albeit modified) hook-over-the-ear design, but liberate heads from handsets via Bluetooth 4.0. Beats says you'll get six hours of playback from a full charge, but should they be low on juice when you fish them out of your kit bag, the company claims a 15 minute pre-gym charge will see you good for a one-hour workout.
If keeping up with LeBron (who "inspired" the Powerbeats²) makes you work up a bit of a sweat, then their IPX4 water resistance should keep them in good condition.
