Ekrin B37S Review

The Ekrin B37S is the new version of the well-known Ekrin B37, making it the brand’s top massager. It is supposed to come with many improvements over its predecessor. Whether this is also noticeable in practice, I would like to tell you in this review. For this purpose, I bought the Ekrin B37S and tested it extensively.

Scope of Delivery and Attachments

The Ekrin B37S comes in a very stylish black box.

If you open the package, you first see a carrying bag. in it is the massage gun with all accessories. In total, the following is supplied:

  • 1 x Ekrin B37S
  • 1 x Ball Attachment
  • 1 x Flat Head Attachment
  • 1 x Fork Attachment
  • 1 x Bullet Attachment
  • 1 x Cone Attachment
  • 1 x Cushion Attachment
  • 1 x Carry Bag
  • 1 x Charger
  • 1 x Manual

As you can see, everything needed to operate the massager is supplied. That’s why we won’t dwell on it for long, but will go straight to the attachments:

The ball attachment is included with almost every massage gun. This is the standard attachment. It can be used for all medium and large muscle groups.

The same applies to the flat head attachment. However, this is shaped slightly differently. This makes it particularly suitable for massaging large muscles, such as the chest or thighs.

The fork attachment has two ends. There is a gap between them. This allows bones, ligaments, and tendons to be left out, for example, along the spine or calves.

The bullet attachment has a pointed, hard end. This allows you to massage individual muscles with high intensity. This is useful for tension and trigger points, for example.

The cone attachment has a similar tip to the bullet attachment. Here, however, it is made of rubber. This makes the attachment less hard and the massage a little gentler.

The cushion attachment is special and soft and has a large surface area. It thus cushions the force of the massage gun. Accordingly, with this attachment, particularly sensitive areas are massaged.

Thus, all the attachments you want in a massage gun are included. At most, a metal attachment would have been advantageous. However, you only need it to massage with oil or gel.

Furthermore, the massage attachments feel not only very high-quality but also pleasant on the skin, which is how it should be!

Another advantage of the B37S is that the attachments are not just plugged on. Instead, they are screwed tight. This means they do not loosen during the massage, which usually happens after some time with other massage guns, because the rubber rings on the attachments become loose.

By the way: The brand’s mid-range model, the Ekrin 365, also has this feature.



The Ekrin B37S has five speed levels. These have the following frequencies:

  • 1st Level: 2,000 rpm – Release Tension
  • 2nd Level: 2,400 rpm – Recover + Flexibility
  • 3rd Level: 2,900 rpm – Deep Massage
  • 4th Level: 3,200 rpm – “Wake Up” Muscles
  • 5th Level: 2,400 to 3,200 rpm (alternating speeds)

When looking at the list, it is noticeable that the B37S “only” has four real speed levels. The last level is a separate massage program that alternates between different frequencies.

The frequency of 2,000 rpm at the lowest level is comparatively high. This was also noticeable in my test. You should not expect a relaxing massage directly on the first level. Instead, the massage feels very intense right away. The higher levels apply even more force (up to 56 lbs !).

Accordingly, the Ekrin B37S is really only for experienced users and athletes who are already accustomed to intense massages. Everyday users looking for a massage gun for relaxation are better off with the B37.

The amplitude of 12 mm also plays into this. It allows the massage gun to massage into the deep tissue. This also loosens deeper muscles and helps them to recover faster.

It is, therefore, very good and important that the massage gun has a fore sensor. This lights up and thus indicates with how much pressure you perform the massage.


Usability and Handling

There is only one button on the top of the Ekrin B37S. This is used to perform the entire control. To do this, first, start the engine by holding the button for a few seconds. Afterward, the individual stages can be switched by briefly pressing the button. The motor is turned off again by holding it for a few seconds.

The handling is not quite as good as the usability. On the one hand, this is due to the handle. This belongs to the larger type. Thus, it cannot be gripped too well. At least it is rubberized, so it does not slip too easily.

The weight is not particularly low either. It is 2.13 lbs (965 g) without the attachment or 2.18 lbs (990 g) with the ball attachment. This is especially noticeable during longer use. A certain amount of strength is needed here to be able to hold the massage gun.


Power Supply

For power supply, the Ekrin B37S has an integrated battery with a capacity of 2,550 mAh. This is a really good value, which is noticeable in the runtime of up to 8 hours stated by the manufacturer. From my own experience, however, I can say that about 6 hours is more realistic – depending on external factors, the level used, and the battery’s condition. However, even that is still very good!

The battery level is indicated by four small LEDs on the top of the massage gun. The following applies here:

  • 80 % to 100 % battery charge: four lights
  • 65 % to 80 % battery charge: three lights
  • 40 % to 65 % battery charge: two lights
  • < 40 % battery charge: one light

The display is thus quite accurate and sufficient to judge the remaining runtime.

The battery is simply charged via the included power adapter. This is plugged into a power outlet and inserted into the bottom of the massage gun. The charging process thus only takes a few hours.

The disadvantage of the B37S, as with many models, is that the battery is not replaceable. So if it breaks, you have to replace the entire massage gun, which is very expensive considering the high price.



I measured the volume from 40 cm and got the following values for the B37S:

  • 1st Level: ~ 51 dB to 52 dB – similar to a conversation
  • 2nd Level: ~ 58 dB to 59 dB – similar to road traffic
  • 3rd Level: ~ 61 dB to 62 dB – similar to a vacuum cleaner on short distance
  • 4th Level: ~ 61 dB to 62 dB – similar to a vacuum cleaner on short distance
  • 5th Level: ~ 53 dB to 62 dB – see other levels

This puts the Ekrin B37S in the middle range. The volume on the lowest level is still more than acceptable and can be easily overheard. However, I already found the massage gun to be quite loud from the second level. Therefore, it is rather not suitable for a particularly relaxing massage. However, this should not be a problem when used for medical or sporting reasons.


Material and Quality

My expectations for the quality of the Ekrin B37S were very high, as I already knew the other massage guns of the brand. Here I was not disappointed either. Even if the material is plastic, the entire massager makes a high-quality but stable impression. In addition, the device looks very modern due to the matte surface and great coloring.

I can’t find anything wrong with the workmanship either. This is on the same high level as the material. Accordingly, you will not find any unclean or even sharp edges.

When it comes to the smell, I can’t say anything other than that the B37S simply smells new. This is the case even though the handle is covered with rubber. Cheap devices often smell chemical here.


Price Performance

I paid about $330 for the Ekrin B37S. That is also their price on the manufacturer’s website and amazon at the time of this review. However, with a coupon code (e.g., MGG20), you can lower the price significantly when you buy it on ekrinathletics.com. So subsequently it only cost $247.50 when I wrote the review.

This makes it even more expensive than its predecessor and one of the more expensive models on the market. Therefore, despite the excellent results in the other categories, I rate the price-performance ratio “only” as “good”.

Conclusion – Ekrin B37S Review


The Ekrin B37S is said to be the improved variant of the Ekrin B37. In my eyes, this is only partly true. Yes, the motor is stronger, and the massage feels stronger due to the higher impact frequencies. But this is only relevant for experienced users and athletes. For a relaxed massage, however, the whole thing is rather a handicap, especially since the B37S is also a bit louder.

Although this may sound negative initially, the Ekrin B37S is one of the best massage guns currently available on the market. It has very good functionality, is very easy to use and convinces with high quality. If you’re looking for a professional massager to fight sore muscles, the B37S is definitely the right choice!
