The Sennheiser IE 300 are powered by a refined version of the company's 7mm Extra Wide Band transducer, which it says will deliver a well-balanced sound signature with excellent sonic accuracy.

Inside the transducer is a membrane foil that's designed to reduce natural resonances and harmonic distortion, a transducer back volume to minimize refection within the earbuds' housings, and a resonator chamber to reduce resonance in the ear canal, which should lead to more detailed treble.
A frequency response of 6Hz – 20kHz means that the Sennheiser IE 300 should deliver impactful bass – although frequencies below 20Hz are generally 'felt' rather than heard in the traditional sense.
Pristine sound on the go
Sennheiser says you can also buy balanced cables with 2.5mm or 4.4mm connectors, which can reduce distortion – so if you're really serious about audio fidelity, the option to upgrade is there.
Available in Europe on January 19, the Sennheiser IE 300 will cost $299.95 / £259 – while global pricing is still to be confirmed, that works out at around AU$390.
That's certainly pricey for a pair of wired in-ear headphones, though those audiophile-friendly specs may convince buyers to fork out the extra cash in the pursuit of pristine sound.
Despite the perception that over-ear headphones always offer superior audio quality compared to their in-ear peers, we've seen an increase in audiophile earbuds in recent years, with companies hoping to tap into the trend for tiny, convenient-to-use audio devices without sacrificing the sound.
It makes sense – many over-ear audiophile headphones are designed for at-home listening, with open back designs that leak lots of sound that could annoy people around you when you're on the move. They're also often quite bulky, with large cables that don't exactly lend themselves to listening on your commute.
With more brands bringing their audio tech to the compact form factor, audiophiles no longer have to sit at home plugged into their Hi-Fi system to enjoy great-sounding music – especially when great portable DACs exist, too. Whether models like the Sennheiser IE 300 can live up to their expectations however, remains to be seen.
