If you were exhibiting at CES and you didn’t have any earphones or headphones to demonstrate, then you must not have gotten the memo that said everyone must make earbuds. Amidst the bewildering variety of mostly mediocre offerings, Sonomax was showing off their latest eers - custom molded earphones. Unlike most other custom molded earphones which have to be professionally fitted, eers come in a do-it-yourself kit that includes a special goo that flows into your ear and hardens to create a custom-fit for your specific ear. According to Sonomax, "Since ears are more unique than fingerprints, perfect fit and comfort can only be achieved with custom-fit earphones.” The PCS-150 uses a single driver. The PCS-250 uses dual drivers and a crossover. Both models include in-line microphones for use with mobile phones. Pricing will be approximately $199 and $299 respectively.
