Tanga offers the Liger Blaze Bluetooth 4.1 Sweatproof Earbuds in Black bundled with the Liger High Output Dual Port USB Car Charger for $29.99 with free shipping. That's $6 under the lowest price we could find for both bought separately elsewhere. (For further comparison, it's also $5 less than our December mention, which didn't include the charger.) Features include a frequency response of 20Hz to 22kHz, passive noise isolation, and up to five hours of playback.
