Portable audio has come a long way over the years. A lot of high-end audio companies are starting to release headphone options, and some of them can be a little expensive. Buy.com has one of those options available, at discount prices.

Sennheiser’s CX 280 High Perfomance Earbuds don’t have a very high MSRP, at $69.95. However, the Buy.com discount certainly makes this purchase more enticing—and affordable. Right now, the retailer has this model for just $29.99, which does include free shipping as well.

These ear-canal, noise-isolating headphones are designed to deliver big sound from a product that travels light. The CX 280 also has built-in volume control and a collection of ear adapters for a perfect fit. Some of Sennheiser’s specs include a 19-20,500 Hz frequency response, a 120 dB sound pressure level, and 16 ohms of impedance.

Buy.com should have this price available for at least the next week. However, you may want to snag a pair (or two) soon; the retailer may pull the offer sooner, if they run out of stock.
