Hello Head-Fi!

It’s a great time to be an audiophile, with countless options for playing high-fidelity tracks away from your main rig. These days, however, your main rig might be your portable setup, too. To further your quest for detailed sound everywhere, today we’re announcing an addition to our compact in-ear family—the IE 300. This earphone brings a unique blend of balance and body to the table for total immersion in the groove, all while highlighting the audiophile qualities of your component chain. We applied a host of acoustic principles to supercharge a refined edition of our 7mm XWB transducer so that your IE 300 packs a punch with every device you connect it to.

The Heartbeat of the IE 300

At the core of each IE 300 earpiece is our dynamic Extra Wide Band (XWB) 7mm transducer, revered for its acoustic performance in a deceivingly compact package. New for the IE 300, it features a new blend of materials in the diaphragm to improve its rest-and-response times for greater accuracy throughout the frequency spectrum. The XWB transducers reproduce sound that is completely unique to the Sennheiser audiophile legacy—in fact, they are developed and manufactured to exacting precision at our world-class facility in Germany.


IE 300 features:
  • Detailed sound with big-yet-balanced presence, in a compact in-ear fit
  • 7mm XWB dynamic transducers with a new diaphragm material blend
  • Unique back-volume manages air flow behind the transducer for low-distortion performance
  • Frequency absorbing resonator chamber mitigates masking effects to unearth critical details
  • Sealed, noise-isolating fit with 3 sizes each of silicone and memory foam adapters (S/M/L)
  • Symmetrical, detachable para-aramid reinforced cable with gold-plated Delta Fidelity+ MMCX connectors
  • Recessed cable sockets for improved strain relief and long-term durability
  • Adjustable ear hooks for a secure, comfortable fit
  • 6 Hz – 20,000 Hz frequency response
  • Efficient 16 Ω impedance for use with a wide range of audio sources
  • Impressive clarity at both SPL extremes with <0.08% THD (1 kHz / 94 dB SPL)
  • Up to 124 dB SPL sensitivity (1 kHz / 1 Vrms)
  • 1.2m cable with stereo 3.5mm jack plug
  • Protective rigid travel zip case and cleaning tool included

Air Traffic Control

A key element of the IE 300’s performance is the back-volume—a miniature room-within-a-room that helps control the flow of air behind the transducer. The direction and overall volume of air is precisely managed as it traverses the transducer system for discernibly defined bass- and mid-range response. Further, we observed a natural increase in the ear canal’s resonant frequency when sealed by an ear tip adapter, producing a masking effect that obscured critical details within the source signal. A frequency absorbing resonator chamber was applied to unearth those subtle (but important) nuances once again.

These technologies work together with the XWB in perfect harmony so that transients are lifted, vocals retain their silky character, and bass notes are communicated with definition AND thrust. Of course, the IE 300 is a sealed headphone, so 3 sizes of silicone and memory foam ear adapters are included to maximize noise isolation and intended bass response.

The IE 300’s detachable cable fuses swappable convenience with the capability to survive daily use away from home. It features gold-plated Fidelity+ MMCX connectors, each seated within a recessed, 4.8mm-wide socket below the surface of the housing. This yields improved strain relief and stability over standard MMCX connectors—especially when combined with the cable’s para-aramid reinforcement which is rated for thousands of bend cycles. A stereo 3.5mm plug is standard—balanced 2.5mm and balanced 4.4mm terminated cables will be available at a later date (we’ll keep you in the loop). On the move, it all fits inside the included protective rigid carrying case.

This new earphone will be available to purchase first in Japan, Singapore, and South Korea on January 19th, China on February 1st, and globally in March, 2021. We will provide further updates as soon as possible, right here. For more information including pricing visit http://www.sennheiser.com/ie-300. We are excited for you to give it a listen!

The speckles are back! I’ll be checking in on the thread regularly for awhile to answer questions... Sennheiser has provided me with a lot of good data to answer questions we anticipate from the folks here, though please be patient if I have to reach out to the engineers for a particularly tricky question :wink: 👍🏻

These look great. I imagine those shells are comfy too.

Yes, over ear and sculpted smoothly to contour to ear ergonomics... no hard edges against your outer ear.

The included case is pretty sweet too, there’s room for a dongle or thumbstick DAC for a nice system-in-a-pack (because we all know those dongles have a way of running off).

First question!

Are these regular MMCX connectors or the Sennheiser stuff found in the other models?

@Ichos There are a few types of MMCX connectors out in the world; these are Fidelity + MMCX connectors. The connection is slightly recessed inside the shell so that The connection is more durable against mechanical stress, but as long as the Jacket near the cable termination is no larger in diameter than 4.8 mm, you should be able to use it. The cable Sennheiser includes is low on microphonics and should last at least 500 connection cycles, and there are 4.4mm and 2.5mm balanced cables coming soon.

Well, the whole IEM is coming soon, but you know what I mean 😁
