Anker SoundBuds Curve | $21 | Amazon

Anker’s SoundBuds Curves were a runner up in our recent affordable headphone poll (they were only beat out by Anker’s own SoundBuds Slims), and you can grab a pair for just $21 today, down from $28.

The SoundBuds Curve are the sportiest member of the SoundBuds family, and are designed with active users in mind. Their ear wings ensure they stay put while you exercise, and an internal hydrophobic coating means your sweat won’t fry them. Their best spec though? 12.5 hours of battery life, which is basically unheard of in the space. Even if you already have Bluetooth headphones you like, it might be worth grabbing an extra set to keep in your gym bag.
