With the potential to customise their sound in ways we've never seen before, we have to admit we were excited when these arrived. They're on sale now.
Like many high-end earphones, these are to be worn with the cable going up over the top of the ears. It gives a more secure fit, but the 'phones can be comfortably worn in the more traditional way quite comfortably, should you really want to.
They're extremely well-built, with cabling that easily detaches from the earphone enclosures for easy upgrade or replacement in the future. We found them to be comfortable from the word go, and easily enjoyable for several hours on end, depending on which tips you use.
A range of such tips are provided in the box, from traditional silicone plugs, to double-flanged silicone, to stiff foam. As with many things in life, experimentation here is key. Take some time to find the right fit for your ears, and ensure a good seal in the ear canal as this is critical for bass conduction.
One of the most interesting and unusual aspects of this earphone involves a small screw on each enclosure. Using the supplied screwdriver-cum-earwax remover (not a tool we get to write about often), you can turn the screw to increase or decrease bass intensity to your liking. We'll come to this again later.
Inside, and unlike the competing Shure SE530s and Ultimate Ears triple.fi 10s, the IE 8s use just a single dynamic speaker driver instead of the aforementioned models' use of three. Sennheiser believes such designs offer wider frequency response ranges, lower distortion at higher volume levels and a greater resistance to damage from knocks and bumps.
