Harman Kardon have introduced the addition of a couple of new products, the Harman Kardon Drive+ Play 2, Guide+Play GPS 500 we wrote about earlier and the HK 700 Series in-ear noise-isolating earphones to its audio line-up. The HK 700 Series noise isolating earphones bring the sound experience to the next level, providing brilliant sound for personal use. The HK EP 710, EP 720 and EP 730 take the comfort of in-ear earphones and incorporate the amazing sound that has come to be expected from Harman Kardon products. Noise canceling occurs naturally with the HK 700 earphones, which were designed to seal comfortably in the ear canal. The HK EP 710 ($99.95), will be available December 2006, HK EP 720 ($149.95), October 2006, and HK EP 730 ($199.95), October 2006, are offered in black or white.
