Block Outside Noise with Sennheiser Sound-Isolating Earphone, $7.99 Shipped (After Rebate)

Far and away the best deal on “canal- phones” I’ve seen yet, Newegg has the Sennheiser CX 300 on sale for just $7.99 (after a $15 trade-in rebate). The icing on the cake: free shipping.
As I’ve noted in the past, I absolutely love these kinds of phones, which fit snugly enough inside your ear canals to reduce outside noise. The CX 300 comes with three sleeve size so you can achieve an optimal fit. However, that’s about all it comes with: You don’t get a carrying case nor even a cord wrap.
Even so, CNET gave the CX 300 a “very good” rating of 7.3 out of 10, while readers scored it even higher: 7.7. Needless to say, if you’re still using the cheap-o earbuds that came with your iPod or other MP3 player, it’s time for an upgrade. The CX 300 should deliver noticeably better sound while affording the benefits of in-ear noise isolation.
The rebate deal, which requires you to mail in any old/used/broken pair of headphones (yeah,kind of a hassle), expires July 31. Even if you decide to skip it, $22.99 is still a killer deal on these earphones.
