Ekrin B37 vs B37S

In this Ekrin B37 vs B37S review, we will compare Ekrin Athletics’ most popular massage gun with its highly-rated, updated version aimed at professionals and other demanding users.

Is the Ekrin B37, a device that can undoubtedly compete with similar models from well-known brands, the right fit for you? Or should you rather invest in the upgraded Ekrin B37S?

This side-by-side comparison will help you find out.

Comparison: Ekrin B37 vs B37S

Amplitude

Both the Ekrin B37 and B37S have an amplitude of 12 mm, which is considered suitable for a percussive massage experience and in line with several popular massage guns on the market.

Force

While they do have the same stall force of 55 lbs, the Ekrin B37S generates 30% more force at speeds 1-3 (see below). It is also equipped with the Reactive Force Sensor, which shows when you are about to reach the maximum stall force for that particular speed.

Frequency & Speed Levels

Starting at 1,400 compared to 2,000 percussions per minute (ppm) on the lowest speed level, the Ekrin B37 offers a slightly bigger range for you to choose from. On paper, both devices come with five different speed settings. The B37S has a unique feature, however.

While the intensity of the B37 increases gradually with each level, the frequency of the B37S alters between 2,400 and 3,200 ppm on level 5. This is done to intentionally confuse the muscle and help avoid a plateau in your recovery, a feature special enough to call this round a draw.

Connectivity

Unfortunately, neither the Ekrin B37 nor the B37S have the ability to interact with your smartphone. If you would like to easily track your treatment sessions and follow warm-up and recovery routines used by professionals, consider the Hypervolt and Theragun brands.

Battery

The Samsung Lithium-ion battery inside the Ekrin B37 and B37S has enough power for up to 8 hours of massage treatments, which is far above the market average. Considering that each session only takes around ten minutes, both devices will last for weeks on a single charge.

Noise

The two competitors are tied once again when looking at the respective noise level – both max out at around 55 decibels (dB). However, the B37 starts at slightly less than 50 dB, while the B37S operates at only 35 dB on the lowest speed and is therefore better suited for quiet environments.

Attachments & Accessoires

With the Ekrin B37, you receive four interchangeable head attachments to personalize the massage experience to your needs. Two additional massage heads were added to the B37S:

• Bullet: Pinpoint treatment including hands, feet, and knots
• Cone: Silicone tip for targeted treatment near tender and bony areas
• Flat: Great for overall use
• Fork: Designed to treat the spine and neck
• Round (Foam): Overall use on large muscle groups
• Round (Silicone): Low impact for treating sensitive and sore areas

Furthermore, the massage heads of the B37S now lock in place, preventing them from popping out. Both models ship with a carrying case and a charger.

Weight & Dimensions

In the final round of this Ekrin B37 vs B37S comparison, we will have a quick look at the weight and dimensions of the two massage guns. Both weighing the same at 2.2 lbs (1 kg), they also take up the same amount of space in your gym bag – meaning we end this review with another draw.

Conclusion: Ekrin B37 vs B37S

The Ekrin B37 convinces with a high stall force and more possibilities for personalization when it comes to available frequencies. At the same time, the engineers at Ekrin Athletics somehow managed to make the device both quiet and extremely resourceful in terms of battery usage.

One reason to upgrade might be if you feel that the B37 is not as powerful as you would like it to be on the lower levels. In addition, the Ekrin B37S has the unique ability to alter its frequency. Lastly, more massage heads mean more possibilities to personalize the massage experience.
