14 DAY TRIAL // Shure researchers said they came out with a really innovative development - the earphones code-named E500PTH, which feature Triple Hi-Definition Drivers - one tweeter and two woofers - and sound isolating sleeves that block over 90 percent of ambient noise.
"Because every ear is different, the Premium Accessories Kit includes three sizes (S, M, L) of the Flex and Clear Flex Sleeves as well as one universal-fit pair of Foam and Triple Flange Sleeves. Experiment with the size and style that creates the best fit for you-a good seal is key to optimizing sound isolation and bass response as well as maximizing comfort during extended wear," said the company.
Moreover, if you are a high-tech fan, you should also see how they look - pretty black nice. But the features are better than the looks, as the earphones offer you a Push-To-Hear Control that activates a VoicePort microphone enabling conversation without removing your earphones, as you can also adjust levels of external sound for an enhanced sound quality.
On the other hand, the VoicePort microphone capability has been developed to pick up the human voice, and it is similar to the microphones used in Shure QuietSpot cellular headsets.
If the little earphones already made your head spin, I should add the last detail - the Premium Accessories Kit - which comes with an adapter, a carrying case and a level attenuator.
