Newegg offers the
Sennheiser HD 429s Over-Ear Headphones in Black for $34.95. This
$10 mail-in rebate cuts it to
$24.95. With
99 cents for
shipping, that's $9 under our September mention and the lowest total price we've seen. (It's also a current price low by $17.) They're compatible with most smartphones and tablets and feature an 18Hz to 20kHz frequency response, 32 Ohms impedance, -39dB sensitivity, and tangle-free cord. Rebate ends January 27.
