The smallest wireless ear plugs we’ve ever tested

Simply impressive.

Swedish Earin impressed with good sound and very compact design when we tested their first set of “true wireless” earplugs a year ago. However, we noticed that the connection between the two plugs was a little too unstable to get some comprehensive recommendation from us.

Earin actually showed up the sequel M-2 already at the CES fair last January, and then look at them at the mobile show in Barcelona. After that, it has been quiet. This is partly due to the fact that Earin was purchased by the artist Will.i.ams company i.am +, which meant that the European launch was postponed indefinitely. Now they are ready for the market and we have received a testimonial.

Earin M-2 – Extremely portable

The design is strictly not very different from the first generation, but an important change is that M-2 has used so-called near-field magnet induction for the connection between the ear plugs. The same thing we saw in Optomas NuForce BeFree8 recently, and that worked well.

In the package, which, with the exception of the cardboard box, is extremely made in environmentally friendly cork, we find a short charging cable and a total of five pairs of ear pads – three in foam and two in silicone. For the undersigned, who usually prefer silicone pads, this is one of the cases where the skulls look the best. The silicone pads seem to be a bit strange, so that they slip too far down the plug and I get the earpiece too far into the ear.

With pillows that fit well, I think you can run or otherwise work with these without falling out, but be aware that they are not sweat or moisture resistant in any way.

The case also looks like last and differs from most other products in the category because it is shaped like a thin cylinder instead of a small box. If we were to compare them with something, there would have to be a small emergency ladder or the like.

It makes it relatively easy to carry them with them in your pocket, even though the case is thicker against the bottom. It is not thicker than a slightly comfortable lipstick, and it also contains almost three full charges of ear plugs. Battery life is otherwise specified for four hours per charge, giving it a total life of 14 hours, which is solid, especially considering how small the Earin M-2 actually is.

Earin M-2 - test

The Earin M-2 is impressive little ear plugs. The new generation has been pleased with some of the childhood diseases from the first version.

Touch panels are new

Because of this, extremely compact and discreet ear plugs, especially when we consider that the small houses must contain all that is usually placed in one or more small boxes on the cord. They stick a few millimeters out of the ear, but are still the most compact products of this kind we’ve been over. Unlike the first generation, they also have a small touch panel on the side of each plug, which offers much needed control capabilities.

At the same time, the plugs are so small that it is difficult to handle them without getting away from the touch panel, which would like to give some unintentional stops in the music, for example, just adjusting the fit a little. It’s a little annoying. The two plugs are completely identical outside, so you can put them on which side of the case you want. They will also recognize what is right and left automatically after which ear you put them in.

Earin M-2 - case

The Earin case still uses Micro USB to charge.

The connection is at least considerably better than last, and it seems that the magnet induction does exactly what it will do in Earin’s case. Here there is no driving outcome either indoors or – the biggest problem earlier – outdoors.

The only thing we’ve encountered with problems with this is that the plugs for some reason both require a separate connection to the mobile and when you take them out of the case, sometimes it’s the only sound in one plug – for despite the fact that the touch controls on both are active and they are both connected. It’s annoying and hopefully something Earin can get organized with an update.

Transparent mode

The plugins have a corresponding app, but it is quite thin in terms of functionality. You can check the battery status, enable the “transparency” mode that will release sound from the surroundings using the microphones, change the “gain” and balance right / left.

The mode that releases sound is convenient if you want to receive a message from a colleague, but you will not remove the earplugs. It can also be adjusted both in volume and whether it will receive sound from distant or near, and it works pretty well.

You can also put them in auto mode, where the plugs themselves adjust how much sound is released, presumably for what they snap into the microphones.

Earin also claims that M-2 conducts Intelligent Noise Reduction, without being able to hear that they actually do any electronic noise reduction. What we can hear, however, is a fairly significant noise, but it disappears quickly when you turn on music or other sounds.

Earin M-2 - in the ear

The Earin M-2 almost disappears completely from the eyes in the ears. If you want to hear the surroundings, you can enable the transparency mode.

Earin M-2: Good sound, but not quite in the top class

The sound is still solid from Earin, with an airy and large sound image and great balance between the various parts of the registry.

They might have gone deeper in the bass, and for example, we heard the beginning of Burak Yeters ‘Tuesday’ considerably more backdrop shaking in other headsets. We also lack some resolution and sharpness in the vocal area – they simply sound a bit distanced, as if the sound passes through a thin filter before it reaches the ear canal.

The sound balance is a bit on the hot side, and combined with the marginally unclean treble it makes them at least very comfortable to listen to. Here it is possible to turn up the sound far without making it cuts or otherwise uncomfortable.

Very good conversation sound

Earin M-2 review

The case is oblong, relatively compact and should fit well in your pocket. The buttons are clicked in place with magnets. 

Earin impresses the sound during phone calls. It’s simply stunning how good M-2 is on filtering away the noise and focusing on your voice, even in some very noisy surroundings. Especially when it comes to how far away your mouth is the microphone here – if Apple had reached this level of engineering, they probably could drop the slightly unclear stick hanging down from their AirPods. We also like that we are served the voice of both ears, which is far from the case for all products of this type.

The Earin M-2 is also suitable for movies and games, as the delay between sound and image is completely unmistakable. It’s great, and no matter, of course, on “true wireless” products. A never-so-called minus may be that they only use Bluetooth 4.2 for communication between mobile and plug, not the newer Bluetooth 5 standard. The range is about the standard for this type of product.

As previously mentioned, battery life is stated to be four hours per charge, and it may appear as tiny on the optimistic side. Based on our use during the test period, we believe you land somewhere between three and a half and four hours, but that’s enough power for more than three charges in the case.


Earin M-2 sound quality

We found that the Earin M-2 gave impressive sound quality even in a fairly noisy environment.

The Earin M-2 is really a pretty fascinating product. They are extremely small and unobtrusive where they are in the ear, and Earin has managed to polish away most childhood diseases from the first edition.

The sound is good, though not the best in class, and Earin does the most reasonably well. If they are able to control the problem that only one plug is connected, we have strictly not much more to postpone on them. Battery life is not quite in the top class, but we can not expect it either, and it’s a compromise we’re willing to enter into.

Aberet is possibly the price. M-2 currently does not have its own Norwegian price, but is quoted at $249 in the online store, including shipping, but not VAT and customs handling fee to Norway. We would nevertheless have waited for Norwegian stores to take them in – and possibly until they get corrected in the mono / stereo connection. If it’s in place, we’re probably willing to raise the grade a little bit.

Earin M-2: Our opinion

Still some small issues to fix, but Earin is approaching.


  • Extremely compact and discreet
  • Comfortable and airy sound
  • Good call quality and stereo sound
  • Stable connection
  • Charges quickly in the case


  • A little bit of trouble with mono / stereo sometimes
  • Lacks some resolution in the tweeter and middle tone
  • No tremendous battery life
  • Touch controls can be a little messy to use
  • A little expensive

Good alternatives to the Earin M-2

Apple Airpods

Apple’s completely wireless variant is probably the best selling item in this category, and it’s not without reason. In fact, they are experienced as completely seamless in use, and in addition have the best battery life, almost all of them.

Big parts of the experience are due to Apple’s W1 chip, which provides power saving, better range and a few other features none of the others can stand. Especially expensive, AirPods are not, even if you get better sound with others.

Jabra Elite 65T

If you want to save even a few doggies, the Jabra Elite 65t is a good choice. However, these are not sweat resistant (but Jabra also offers a model called Elite Active 65t), but nevertheless offers a good combination of sound quality, wearing comfort and battery life. However, they are not as compact as the earin plugs.

Sony WF-SP700N

Sony’s new completely wireless plugs took the recipe of the very good WF-1000X and put on a slightly more sporty design that makes them more suitable for those who would like to use them for exercise. However, an annoyance is the case that does not fit the earwings without turning them all the way around, and the battery life is also in just three hours. What Sony is about is, however, active noise reduction.
