Shure has unveiled three new models of Sound Isolating Earphones at CES 2007 in Las Vegas.

Building on the company's E Series earphones, Shure has introduced a new line of earphones that it says "offer consumers a number of exceptional attributes including new sound signatures, modularity, style and ergonomics".

The new lineup includes the SE210, the SE310, the SE420 and the renaming of the E500 earphones launched in the UK last year to the SE530/SE530PTH.

The £99.99 SE210 is designed with a Hi-Definition MicroSpeaker to provide full-range audio distinguished by an optimal high frequency response.

The £169.99 SE310 utilises a Hi-Definition MicroSpeaker with Tuned BassPort technology which showcases extended range audio and enhanced bass for optimal high frequencies and enhanced low-end performance.

Finally the £249.00 SE420 feature Dual TruAcoustic MicroSpeakers – a dedicated tweeter and woofer.

All earphone sets will be launched later in the year.
