Shure ships three premium earphones
Shure has released three new pairs of high-end, sound-isolating in-ear headphones, including the single-driver SE315, dual-driver SE425 and triple-driver SE535. The latter two were introduced at this year's CES. The SE315 set has a vented driver and sports a detachable cable that can be formed for a comfortable fit. It ships with isolating tips that can provide as much as 37dB of ambient noise.
It gets a sensitivity of 116dB/mW at 1kHZ and a 27 Ohm impedance. Frequency range is set at 22Hz to 18.5kHz. It ships in clear or black.
The SE425 set is similar in spec, though gets two drivers. Its maximum Sound Pressure Level is somewhat lower, at 109dB/mW at 1kHz. The frequency range is nearly identical, albeit slightly higher, at 20Hz to 19kHz.
The SE535s use three drivers, with one being a tweeter. As such, they can reproduce the highest frequencies, at 18Hz to 19kHz. Their 36Ohm impedance is also the highest. They ship in clear or bronze.
All three share gold-plated 3.5mm connectors.
While prices haven't been revealed, the SE315s may cost at least the same $300 as the SE310s they succeed, the SE425s about $400 just like their SE420 forebears and the SE535s should cost at least the $500 of their predecessors, the SE530s.
