I use a Rowkin Mini for the same sort of stuff, most often while commuting. For spoken content it renders intelligibly, and it is tiny and comfortable to use. It also lasts a few hours on a charge and lives on my keyring. Devices like this exist in a local optimum of convenience, as long as they and their audio sources both do Bluetooth right. (I tried a bunch of the cheap ones off Amazon before settling on the Rowkin. It really is a lot better!)
Yup. They have a new line out, so are probably clearing old stock with the discount. That link is the exact model I have, though, and it's been awesome; I might pick up a couple of spares just to have them against need.
For at-rest listening, God made Sennheiser.
