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.

Quality

The amount you pay for this DAC is absolutely worth it. I'm using it with my PC, and I also have a Fiio KA13. It provides 32-bit 48000Hz audio output, and it's really good. I'm connecting it via a USB-C port and one extension cable (AGARO 3.5mm Aux Male to Female Extension Cable, Gold Plated). There’s no audio loss whatsoever.
The only minor issue is when you use it with a mobile device — the blue light can be a bit annoying. However, that's more of a personal preference. It also makes some noise with certain songs, but that's actually a known issue with the CS46L41 chip. There's no need to worry though; unless you've used a high-end DAC before, this will be more than enough for you.
Bass and clear vocals

Excellent sound quality

After searching internet found this dac which has multiple input options and support 165*2 watts passive speakers and 350 watt passive subwoofer for future extension, tested with all input modes, bluetooth input feels a bit of low quality as it only supports sbc and aac codecs only, however if you want to use mobile via wired, alternative option is to use audiocular d08 cs-pro usb-c to 3.5 mm and 3.5 mm to rca input (cable creation brand). Optical input mode supports PCM (loss less stereo output) and Digital compress audio multichannel only) these are specific to Sony X-80J 65 inches

Thanks a lot Pritam Ji for suggesting me to use a balanced cable with my Moondrop Aria IEMs and thanks a lot for ordering Moondrop Aria filters for me. The Audio Store goes out of the way to serve Indian audiophile community.
The way my IEMs sound with a balanced cable and Shanling UA2 Plus DAC & Amp are unprecedented!
I am grateful Pritam Ji. 🙏🏻

The empathetic support that I got (as a budding audiophile) from Pritam Ji at The Audio Store is unparalleled. I am grateful Pritam Ji. 🙏🏻

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.
