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.

Just bought it and started using it with my IFI Zen Stack - feels awesome.
This was a natural pick for me, since I wanted to have a completely balanced setup for my HiFiMan Sundara.
Nothing much to add, if you want an optimal balanced setup without spending too much, then look no further.
Thanks AudioStore for being blazing fast with your delivery. I got it withing 48 hours of placing my order! Kudos.

For my HiFiMan Sundara, this is a nice quality 4.4 mm balanced cable. I am buying this for the second time, since the first one got destroyed by my kids.
If you are looking for a good quality 4.4 mm balanced cable, look no further.
Audio

This product is reached my expectation good purchase good audio signal transmission no noise at all.....thank you the audio store👍
Yes

I have used lots of TWS even high end of Samsung and Oppo worth 10K. But IEM sound signature is great! This is my second IEM. I had KZ-ZEX. It has dual driver with electrostatic. Compare with that MoonDrop Chu 2 is better clear and smooth sound signature even with single driver. I am using with Audiocular DAC cost 750. Just go with MoonDrop Chu 2 if you are music lover. Thanks.
Great packaging and quick delivery
Loved the theme of the store and the support of the customer service for every problem I faced. I would be interested in buying new things from the audio store in future.
Good Quality and got a clear case for the player.
Thank you 😊

The quality is great, I felt that the base got a bit reduced and mids and treble enhanced using the same. They look premium. The only downside is that they are slightly bulky as the cable is 16 core and sometimes you can feel it behind the ears. Overall a great cable to upgrade your entry level iems to support balanced output

After going through many websites, I came to know about this particular dac, which is purely oriented on audio amplification with dedicated chip unlike other dacs available under 2k, so ordered and received in two days, to my surprise it has significantly enhanced the audio experience on oneplus 13R, with wired earphones (redmi hi-res of 500 INR), usb type a to c adaptor really came into handy and detected as HiFi audio in my dell laptop, cherry on the cake was the pouch, I didn't expect a pouch, very happy with the purchase...

Visited thier store cum experience center it was very great place for sound lovers . Especially like their display of products in thier demo room.The Owner /Staff were cooperative and also suggested me several IEM's before i select one.

I was looking for IEM Tangzu but they were loud and bass was little low as per my ears.Owner or Associate at store suggested me Audicular i liked the sound as well as bass effect its great product.
The Sennheiser IE 200 delivers impressive value for the price. Comfort-wise, they’re lightweight and fit snugly thanks to the ergonomic design and included foam/silicone tips—great for long listening sessions. Build quality is solid despite the plastic housing, and the detachable braided cable adds durability. As for the sound signature, it’s balanced and clean—tight bass, clear mids, and smooth treble without harshness. Bonus points for the dual-tuning feature that lets you slightly tweak the sound. A fantastic entry-level choice for anyone looking to step into the audiophile world.
There sound is pretty good
