Basic Specifications
  • Continuous / maximum playback time: 7h / 24h
  • Waterproof performance: IPX7
  • Supported codecs: AAC / SBC



Equipped with Knowles balanced-armature drivers

The Knowles balanced-armature driver provides a well-balanced sound that is easy to listen to even after long hours of use. It delivers a sound that is more detailed and delicate.


Up to 24 hours of playback is possible when used with a charging case

The earphones are extremely lightweight at only 4.7g per side, but can be used for about 7 hours of continuous playback, and can be used with the charging case for up to 24 hours of playback, so you can enjoy long hours of playback without worrying about the remaining battery. In addition, the charging case has a strap hole so you can attach the included strap or your favorite strap to carry it around.


Waterproof performance equivalent to IPX7

With a special waterproof structure equivalent to IPX7, it is resistant to sudden rain and sweat during sports and can be used as is. It is also completely submersible, so it will work even if it is accidentally dropped into water. (We do not recommend intentionally dropping it or immersing it in water for a long time.)



Easy operation by just touching the earphone

Various operations can be performed by touching the touch sensor on the back (face plate) of the earphones. You can start/end an incoming call, play/stop/forward/backward music, and start/end ambient mode. It is also possible to use the earphones with only one side of the earphones (monaural mode).


Supports contactless charging

The MTW100-BA supports contactless charging, so it can be charged simply by placing it on a charging pad (wireless charger). This frees you from the hassle of plugging and unplugging the USB cable every time you want to charge. (Wireless charger is not included in this product, so please prepare it separately.)



It is a standard or slightly higher quality package in its price range.

Build quality

The build quality meets the standard of the price. The charging case is smooth to open and close, with little wobble in the lid.


The shiny plastic design with a slightly cheap texture may not be to everyone's taste.

The IEM-type design provides a good fit. Sound insulation is good if you choose the right eartips, but there is not much room in the earphone compartment, so the choice of eartips is limited.

Connection quality

I tested it by connecting it to a Cayin N6II/E02 with AAC. The connection quality is excellent for the price range; I don't know because I haven't been in crowds due to the COVID-19 craze, but it's stable in the home. Distance tolerance is excellent, and the connection is seamless and intact even at a distance of about 5 meters. The music plays fine even with a barrier between us, and there are no interruptions.


There may be a small amount of white noise, but most people probably won't notice it.


Hear-through Performance

The performance of the hear-through isn't very good. There is a blatant hum that sounds like a jittery roar. It may be quite unpleasant for those who are bothered by it.



Sound quality

The Shanling MTW100-BA seems to have been tuned to emphasize midrange staging and sound less tiring to listen to. The sound is thick and full, with good coloration. It is a little less than refreshing and sharp, so it may sound sleepy to some people.

Sound quality general comment
  • Original sound fidelity: A
  • Recommendation: B
  • Personal preference: B-


The sound of the Shanling MTW100-BA is somewhat retro-sounding in some respects, and has a rather compact, boxy feel that allows you to enjoy music in a private atmosphere.


The overall picture of the music is easy to understand, but the obvious drawback is that it lacks a sense of scale and tends to sound somewhat cramped. The listening experience is very stable, and you can listen to it forever without getting tired.

General comment

The Shanling MTW100-BA is comfortable to wear and has a powerful battery performance for long hours of playback. Its sound quality is such that you will not get tired of listening to it for a long time, making it a perfect companion for long journeys. If you like gentle sounds, you'll love them, although they can be a bit drowsy at times due to their rather relaxed spatial expression.
