Sennheiser’s latest IE 300 in-ear earbuds aim high, real high

January 12, 2021

At CES 2021, Sennheiser have announced their latest in-ear headphones, and these earbuds are clearly targeted at serious listeners.

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.

Unlike wireless earbuds like the Apple AirPods and the Sony WF-1000XM3, the Sennheiser IE 300 come with a 3.5mm cable, with a gold-plated connector for durability, and users have the option of buying balanced cables with 2.5mm or 4.4mm connectors, which can reduce distortion even further.

To ensure noise isolation and comfort for long listening sessions, the IE 300 has an adjustable flexible ear hook, silicone and memory foam ear adaptors that come in three different sizes. Available in Europe on January 19, the Sennheiser IE 300 will cost around $360.
