Sennheiser IE 100 PRO Wireless In-Ear Monitors – Studio-Grade Sound, Wireless Freedom
Upgrade your listening experience with the Sennheiser IE 100 PRO Wireless, the next-gen evolution of the acclaimed IE 40 PRO. Designed for musicians, audio engineers, DJs, and discerning audiophiles, these professional in-ear monitors deliver exceptional sound clarity and versatility—whether you're on stage, in the studio, or on the move.
Combining the powerful IE 100 PRO earphones with the innovative IE PRO BT Bluetooth Connector, this wireless IEM system connects effortlessly to iOS, Android, macOS, or Windows devices via Bluetooth 5.0. Thanks to aptX Low Latency, you’ll enjoy perfectly synced audio for video monitoring and performance.
Precision Sound, Anytime, Anywhere
Equipped with 10mm single dynamic drivers, the IE 100 PRO Wireless delivers warm, punchy sound across a wide 20 Hz – 18 kHz frequency range. Unlike multi-driver earphones, this single-driver system avoids phase issues, offering a harmonious, distortion-free sound even at high SPLs (up to 115 dB). Whether you're practicing, producing, or performing, every detail is delivered with precision.
All-Day Wireless Listening with Studio-Level Control
The included IE PRO BT Connector features an in-line microphone and remote for seamless call handling and music control. With support for SBC, AAC, aptX, and aptX Low Latency, the sound remains high-fidelity across devices. The internal rechargeable battery powers up to 10 hours of continuous playback and charges fully in 2.5 hours via USB-C.
Built for Comfort, Engineered for the Stage
Crafted for long sessions, the lightweight 5.6 oz design includes an ergonomic earmold shape and comes with silicone and memory foam ear adapters for a personalized fit. The medium memory foam tips offer up to 26 dB passive noise isolation, reducing ambient distractions and ear fatigue, even in loud environments.
Wired Option for Maximum Flexibility
For traditional monitoring setups, the IE 100 PRO Wireless includes a rugged 4.3' detachable Y-cable with a 3.5mm jack, reinforced ear hooks, and proprietary cable ducting for stage durability. Use it with wireless bodypack receivers, headphone amps, or mixing consoles for a complete IEM solution.

OUR HONEST REVIEWS FROM THE CO-FOUNDERS & AUDIOPHILES
View allTRUSTED BY OVER 35K+ MUSIC ENTHUSIAST
Let customers speak for us
from 5211 reviewsThe soundstage and imaging in games is awesome. I can hear every minute detail
Very detailed sound and wide sound stage
The quality of the product really good and audiostore experience as well
The audio quality was great... And this is the first time I m buying from audio store... It was good experience and it came very faster than i expected !
The resolution of audio has improved drastically due to the balanced cable. The cable makes my Shanling UA2 Plus DAC + Amp to provide more power to the drivers of my Sennheiser HD620S headphones. So, the volume of the headphones has doubled.
The build is solid and the most impressive thing is the flat sound stage.It is recorded to use a portable DAC to get the best sound possible.Not recommended for bass lovers

Good
Very prompt response
It's very good very energetic sound
Audio quality is too good
The fitting and impact of sound quality and comfort is amazing I would love to buy more this kind of eartips
Most convenient

This was a gift for a friend of mine. The shipping took some time but when it reached them it was shipped the same day and after two days it was received. It came in perfect condition. I'll copy my friend's review below:
"This is most balanced IEM with a touch of warmth among everything out there. The Bass is just a bit much and with a 3db high-pass filter it became perfect. It doesn't get much better from this. The soundstage and imaging is decent and competes with +800$ stuff. The tuning, resolution and timbre is one of the best even under 2k. I'm very much in love with them. The comfort is pretty decent. I haven't got tired of them even after long hours."
The audio quality is very crisp and refreshing
The sound just amplified after using this with my kz castor pro IEMs....it is amazing.
