Wireless earbuds are becoming increasingly diverse, and the MONSTER M100 earphone takes a different approach from traditional in-ear TWS models. Instead of relying on a conventional earbud shape, it uses an earclip design intended to provide a more secure fit for everyday movement.
MONSTER M100 also follows the broader trend toward more versatile TWS wireless earbuds, combining a secure wearing style with modern Bluetooth connectivity and everyday calling features.
The M100 also combines Bluetooth 5.4 connectivity, 3D surround sound, intelligent call noise cancellation and a charging case with a digital battery display. Its rated battery life reaches up to 23 hours when the earbuds and charging case are used together.

An Earclip Design for a Different Wearing Experience
The most noticeable feature of the MONSTER M100 is its earclip construction.
Traditional TWS earbuds sit inside the ear canal and depend heavily on the shape of the ear tips for stability. The M100 takes another route by using an earclip structure, which can be appealing to people who find conventional earbuds uncomfortable or less secure during movement.
This makes the M100 particularly interesting for commuting, walking and light exercise. The open-style physical design can also make the headphones feel less intrusive than deeply inserted earbuds, although the actual fit will naturally depend on the user’s ear shape.
The listed product weight is about 43 grams, while the earphones are rated IPX4 for water resistance.
Bluetooth 5.4 Keeps the Connection Current
The MONSTER M100 uses Bluetooth 5.4, putting it on a newer wireless connectivity standard than many budget TWS headphones still using older Bluetooth versions.

The headset supports HSP, HFP, A2DP and AVRCP profiles and has a listed transmission distance of up to 10 meters under suitable conditions.
For everyday users, the more important point is not simply the Bluetooth version number. A stable wireless connection matters when switching between music, calls and other phone activities. The M100 is therefore positioned as an all-purpose wireless headset rather than a product designed only for music playback.
3D Surround Sound Focuses on a Wider Audio Presentation
MONSTER lists 3D surround sound as one of the M100’s main audio features.
According to the product specifications, the earphones are tuned to create a wider soundstage while retaining bass and clearer mid- and high-frequency details.
That approach should make the M100 more interesting for users who listen to different types of content throughout the day. Music, videos, podcasts and casual gaming can all benefit from a more spacious presentation compared with a very flat-sounding wireless headset.
However, “3D surround sound” should be viewed as an audio-processing and tuning feature rather than a replacement for a dedicated multi-speaker surround system.
Call Noise Cancellation Is Designed for Voice Communication
Another useful feature is the M100’s intelligent call noise cancellation.
The headset uses a noise-cancelling algorithm designed to distinguish the speaker’s voice from surrounding background sounds during calls. MONSTER specifically positions the feature for environments such as busy streets and offices.
This distinction is important because the product listing does not simply describe the M100 as a pair of conventional ANC headphones. Its listed noise-cancellation feature is focused on improving voice communication.
For people who frequently take calls while commuting or working away from home, microphone performance can therefore be just as important as music quality.

23 Hours of Total Playback
Battery life is another practical strength of the MONSTER M100.
The earbuds themselves provide up to 5 hours of playback on a single charge, while the charging case adds another 18 hours, bringing the advertised total to 23 hours. A full charging cycle takes about two hours according to the listed specifications.
| Battery detail | MONSTER M100 |
|---|---|
| Earbuds playback | Up to 5 hours |
| Total with charging case | Up to 23 hours |
| Charging time | About 2 hours |
The 23-hour figure is best understood as combined listening time rather than continuous playback from the earbuds themselves. Users who regularly listen for several hours at a time will still need to return the earbuds to the case for recharging.
A Digital Display Makes Battery Status Easier to Check
The charging case includes an LED digital display showing the remaining battery level.
This is a small feature, but it addresses one of the most common frustrations with wireless earbuds: discovering that the case is nearly empty only after the earbuds have already run out of power.
Instead of relying entirely on a phone’s Bluetooth interface or guessing from indicator lights, users can check the case directly before leaving home.
IPX4 Protection for Everyday Movement
The MONSTER M100 carries an IPX4 water-resistance rating.
For users comparing headphones for exercise and outdoor use, water-resistant sports headphones can offer a better balance between wearing comfort, stability and protection from everyday sweat.
That makes the headset better suited to everyday exposure to light splashes and sweat than a completely unprotected pair of earbuds. However, IPX4 should not be interpreted as waterproofing for swimming or heavy water exposure.
For walking, commuting and normal workouts, the rating provides a useful degree of protection, but users should still avoid deliberately exposing the headset to large amounts of water.

Who Should Consider the MONSTER M100?
The MONSTER M100 is not trying to compete purely through a long list of headline specifications. Its combination of an earclip form factor, call-focused noise cancellation and digital battery display gives it a more practical identity.
It could make sense for users who want wireless headphones for commuting, walking, calls and casual exercise, particularly if they prefer an earclip-style fit over conventional in-ear earbuds.
The 23-hour combined battery rating is also useful for people who want enough capacity for a full day of intermittent listening without carrying a separate charging cable everywhere.
At the same time, buyers looking specifically for strong active noise cancellation, audiophile-grade tuning or extensive premium features should compare the M100 with higher-end alternatives before making a decision.
Final Take
MONSTER M100 is an interesting example of how budget TWS headphones are moving beyond the standard in-ear formula. Its Bluetooth 5.4 connection, earclip design, 3D audio, intelligent call noise cancellation, IPX4 protection and 23-hour total battery life give it a practical feature set for everyday wireless listening.
Rather than focusing on one extreme specification, the M100 brings several useful functions together in a relatively straightforward package. For users who value wearing stability and convenient daily communication as much as music playback, that combination may be more meaningful than a headline specification alone.
