The best in-ear monitor (IEM) for a live-streaming setup is the one that fits securely and connects to an output carrying the mix you need to hear. The Shure SE215, Sennheiser IE 100 PRO and Audio-Technica ATH-E40 each offer practical monitoring features, but the available manufacturer specifications do not establish a universal sound-quality winner. Choose by fit, isolation needs, cable and local availability—and confirm your monitoring signal path before buying.
What to check before choosing an IEM
Make sure the right mix reaches your ears
An IEM is the listening endpoint, not a mixer or a source of audio routing. Before buying, identify the headphone or monitor output you will use and confirm that it carries the sound you want to monitor. Depending on your setup, that might be a stream mix, a microphone-and-program blend or another feed. The right connection could come from an audio interface, mixer, headphone amp or another device you already own; there is no single supporting device required for every creator.

Try the included tip sizes and materials, and check that the earpiece seals comfortably and stays put. Shure warns that a poor sleeve seal can reduce low-frequency response; its SE215 guide advises trying a different sleeve if bass seems lacking. A secure seal also matters for isolation, but comfort and fit are personal, so specifications cannot tell you which model will suit your ears.
#1 Best Overall
- 【Upgraded 4BA+1DD Hybrid Earphones &Magnetic Dynamic Unit]】As an upgraded version of K2 ZS10, the Pro features self-customized balanced armatures which include two 30095 drivers for highs, two 50060 drivers for mids.

Prefer wired monitoring unless you have checked wireless latency
A wired connection is the cautious baseline for live monitoring. This is not a claim that Bluetooth always fails; it is a reminder that the consulted product information does not establish low-latency performance for a particular wireless setup. Sennheiser’s wireless product information mentions monitoring between sessions, which is not validation for latency-sensitive live use.
Three wired IEMs to consider
These are feature-based options, not a listening-test ranking. Manufacturer isolation figures below use no verified shared test protocol, so do not compare their decibel values as if they came from the same test.

How to choose between them
Choose by fit and included tips
If you want multiple tip options to try, the SE215 includes a fit kit, while the IE 100 PRO package listing includes foam and silicone adapters. The ATH-E40 listing includes four silicone tip sizes. Package contents can vary by region or seller, so verify the box contents before ordering.
Choose by cable needs
The SE215 has detachable cabling and an MMCX accessory connection; the ATH-E40 has a detachable 1.6 m cable. Those details may matter if replaceability or cable length is a priority. The IE 100 PRO package listing includes a cable, but the cited specifications do not establish a comparable replacement-cable option. Check connector and replacement-part compatibility before purchasing accessories.

Use isolation figures cautiously
Shure states up to 37 dB attenuation for the SE215, while Sennheiser lists less than 26 dB for the IE 100 PRO. Because no common test protocol was verified, the figures do not show that one blocks more noise in a direct comparison. Fit, seal and listening conditions also matter. No comparable isolation figure is established here for the ATH-E40.
Do not infer sound quality from specification ranges
Impedance, sensitivity and frequency-response ranges help describe electrical and published product specifications; they do not establish which IEM sounds better for your voice, music or stream mix. No comparative listening test is available for these three models. Choose based on fit, your output’s compatibility, cable preferences and verified regional availability.

Set up and care for your IEMs
- Identify the output. Trace the headphone or monitor output you intend to use, and confirm that it carries the desired mix. If the feed is missing or unbalanced, resolve routing at the source device or software; changing earphones alone will not fix it.
- Try the tips. Test the included sizes and materials at a safe listening level. Aim for a seal that is secure without causing discomfort.
- Check the fit with your intended monitoring content. If bass sounds unexpectedly weak, reseat the earpiece or try another tip before concluding that the mix or earphone is at fault. Shure specifically identifies a poor sleeve seal as a possible cause of reduced bass.
- Confirm cable and connector fit. Match the IEM’s cable connection to its supplied cable or a verified compatible replacement. Do not assume an accessory fits just because the connector looks similar.
- Keep listening levels safe. Shure advises against prolonged listening at high volume and recommends following its use and care instructions. Reduce the level if listening becomes uncomfortable.
Limits of the available comparisons
The cited product pages and specifications establish manufacturer-described features and figures, not a hands-on comparison. They do not establish comfort over a full broadcast, real-world durability, measured monitoring latency, a shared isolation ranking or a universally best sound. For the ATH-E40 in particular, the Japan page’s discontinued label is a regional status signal, not proof that the product is unavailable everywhere.
