The 'phones have been launched alongside two new headphone amplifiers - the analogue HDVA 600 and the digital HDVD 800, with all three containing the latest sound transducer developed by the German audio experts.
Sennheiser has used scratch-resistant cermaics to create the modern-looking housing for the IE 800 headphones.
The headphones feature a dual-chamber absorber to overcome the "masking effect" - an effect where loud low frequency sounds "mask" quiet medium frequency noise.
"These dynamic in-ear phones offer fascinatingly brilliant trebles, precise bass response and a detailed, lifelike sound image with a frequency response of 5 to 46,500 Hz,” said Maurice Quarré, Director, Product Lifecycle Management, Sennheiser.
Of course, all this tech comes with a pretty severe price tag and the Sennheiser IE 800 headphones will set you back a cool £599.99.
The Sennheiser IE 800 is available from September at selected Sennheiser sales partners.
