Sound quality is okay, not amazing, not terrible. Battery life stands up to advertised and it's appropriately able to handle water – took these on a six day tramp on Stewart Island in the pouring rain and didn't falter once in the rain and cold. Weird issue in that as they're called “Accord” like a Honda, Spotify thinks you're playing it in a car. All in all, good mid-range headphones that are practical and durable but perhaps are missing the sound quality of head phones or very high end buds.
