"I've been waiting for this one to be released and it certainly exceeded my expectations"

Jude Mansilla, Founder of

"You can throw out the flimsy earbuds - these infinitesimal components deliver gigantic sound with minimal distortion."

"We've developed the IE 300's exciting sound by building on the acclaimed IE 800 technology. The high-performance transducer optimized for wideband reproduction and minimum distortion ensures you hear every detail and brings you closer to your music."

Jermo Köhnke, Product Manager Audiophile

"From refining our acclaimed 7 mm Extra Wide Band (XWB) transducer to the nozzle's dimensions or the tube length, we have spent a great deal of effort on each detail, no matter how small, to ensure the IE 300 achieves exactly the right sound quality, giving life and soul to the music you love."

Virgilio Pascua, Development Engineer for Acoustics

"Sennheiser stands for quality in both construction as well as sound, and it’s no different this time. The IE 300 is a very affordable IEM that not only looks nice, it’s also very well built, very comfortable and great sounding."

"The IE300 presents a very cohesive sound with movements that are easily pinpointed and tracked, while the very wide stereo separation really contributes to the overall enjoyment of the music more than some will realize..."

Wiljen, user

"The IE 300 manages to surround you with the track, completely avoiding the 'in-the-head' feel provided by other products.” “... anyone wanting a refined V-shaped sound in this price range should have these on their radar."

B9Scrambler, user

"The IE 300 is really lightweight, so I can ran into zero comfort issues for long-term sessions."

Corgifall, user

"The sound is fun, coherent, clear, refined (have I mentioned that yet? lol), with strong bass response."

FreeWheelinAudioLuv2, user

Detailed Sound Everywhere

The driving force of the IE 300 is a refined version of our 7mm TrueResponse transducer.

Air Traffic Control

A key element of the IE 300’s balanced acoustic performance is the back volume—a miniature chamber-within-a-chamber that helps manage the flow of air behind the transducer.


  • German-made 7mm TrueResponse transducer – for natural balanced sound
  • Newly developed membrane foil for minimized natural resonances
  • Adjustable flexible ear hooks and a choice of ear adapters incl. memory foam
  • Frequency response: 6 Hz – 20,000 Hz
  • Resonator chamber to remove masking resonances
  • Para-aramid reinforced cables with gold-plated MMCX connectors and a 3.5mm plug
  • Impedance: 16 ohms
  • Total Harmonic Distortion < 0.08 % (1 kHz, 94 dB)

In-Ear Peace

The IE 300 ensures that you can enjoy a thrilling hi-fi experience wherever you are.

Inspiring performance

A universal design that feels like it was custom tailored just for you.

It's all about connection

Outfitting the IE 300 with a detachable cable was an obvious choice; however, audiophile-grade sound demands a matching level of mechanical reliability.

  • Single resonator chamber technology
  • Great bass suited for Vocals, Pop & ACG
  • 3.5 mm cable / MMCX connector
