Ekrin B37 vs Theragun Prime

The Ekrin B37 and Theragun Prime, while not the top models of their brands are each among the higher-end massage guns. Accordingly, many choose one of the two massagers. If this is also true for you and you can’t decide on one of the devices, you’ve come to the right place. I have extensively tested both the Ekrin B37 and the Theragun Prime. In the following article, you can read about the differences between the two massage guns and which one you should choose.

Scope of Delivery and Attachments

The complete delivery scopes are listed above in the comparison table. Accordingly, I will refrain from listing them again here. Instead, you can find the differences between the Ekrin B37 and the Theragun Prime in this category right here:

1. The Ekrin B37 includes a fork attachment. This is suitable for a massage in places where bones, ligaments, and tendons should be left out. This is not included with the Theragun.
2. The flat head attachment is also not included with the Theragun Prime but is included with the B37 from Ekrin. It is suitable for massaging larger areas.
3. The Theragun Prime, on the other hand, includes a thumb and cone attachment. These are optimal for spot massage. This job is done on the B37 by the Bullet attachment.
4. There is no attachment for sensitive areas on the Ekrin B37. The Theragun Prime, on the other hand, includes the Dampener attachment for sensitive and bony parts of the body.

A ball attachment is included with both massagers. So the differences here are not too great. You will have to decide for yourself which of these accessories is more important for you.

Functionality

The Ekrin B37 has a total of five power levels. These have the following shock frequencies:

The Theragun Prime has the following five power levels:

There is a clear difference here. Both massage guns have five speed levels. However, the impact frequencies of the Ekrin B37 are distributed over a much wider spectrum. This makes it much more versatile. The first level, in particular, is much gentler and thus more suitable for beginners.
On the other hand, the Theragun Prime can score points for amplitude. It has an amplitude of 16 mm, which is a very good value and makes it possible to massage deep tissue without any problems. However, the 12 mm of the Ekrin B37 is not bad either.

Usability

In terms of usability, the two massagers do not differ much. Both the Ekrin B37 and the Theragun Prime are very easy to use, even if the operation is basically different.
The Ekrin B37 has a single control button. When this is held down, the motor turns on or off. Once the massager is turned on, a quick button press allows you to cycle through the levels.
The Theragun Prime, on the other hand, has three buttons. The large button in the center allows you to start and stop the motor. The two buttons above and below, on the other hand, can be used to cycle up and down through the individual levels.

Handling

In terms of handling, I evaluated the weight and the handle of the massage guns.
The Ekrin B37 weighs 2.13 lbs (965 g) without the attachment and 2.19 lbs (992 g) with the ball attachment. The Theragun Prime, on the other hand, is 2.07 lbs (938 g) without the attachment or 2.11 lbs (958 g) with the ball attachment. Thus, both massage guns tend to be among the heavier ones. Nevertheless, the Theragun Prime has a slight edge, even if it is not really noticeable in practice.

This is due to the handle. This is nice and thin and long on the Ekrin B37. On the one hand, this makes it very easy to grip. On the other hand, the handle makes it easy to massage hard-to-reach areas. In addition, the handle is rubberized, which prevents slipping out of hand. The Theragun Prime’s handle is not quite as easy to hold. It is a bit thicker. In addition, it is not rubberized. Here, only the matte surface should prevent slipping out of hand.

Power Supply

The Ekrin B37 has a Samsung battery for power supply. This has a capacity of 2,500 mAh. This was enough to supply the massage gun with power for about four to six hours in my test. That is a very good value! Charging is also quick with the included power adapter.

Below the button are four small lights that indicate the battery status. The following applies here:

The display of the battery status is thus quite accurate.

Brand and capacity are not known for the Theragun Prime battery, which I find a pity. The runtime of about two hours also does not quite come close to the Ekrin B37. At least charging is similarly fast. The battery status is also indicated by small lights in the Prime. However, this is not as accurate as in the B37 since it lacks information about how full the battery is depending on the number of lights.

Accordingly, the Ekrin B37 is ahead in this category for me.

Noise

For both massagers, I measured the loudness from a distance of 40 cm. I obtained the following values for the Ekrin B37:

For the Theragun Prime, the measurements revealed the following volume levels:

It can be seen from the values that both massage guns reach high volumes. Nevertheless, I see the Ekrin B37 clearly ahead here. It is only very loud at the highest level. On all other levels, however, it is much quieter than the Theragun Prime, which is permanently unpleasantly loud. Accordingly, only the B37 is suitable for a relaxing massage – even if only at lower speed levels.

Material and Quality

In terms of material, both massage guns play in the upper league, even though they are “only” made of plastic. Nevertheless, the massage guns make a very solid impression. Since the surface of both the B37 and the Prime is matte, the material also looks very high-quality.

The same applies to workmanship. The massage guns are very cleanly manufactured. Accordingly, I could not discover any sharp edges or the like. The gaps are also very small.
The only weakness I could find here concerns the Theragun Prime. There is lubricant on the stroke here. You can easily smear yourself here if you are not careful.

In terms of smell, the Theragun Prime is again slightly ahead. This one simply smells “new”. The Ekrin B37, on the other hand, initially had an unpleasant chemical smell. This is often the case when rubber is used. Fortunately, the smell quickly subsided.

Price

I bought the Ekrin B37 from a private seller for about $230. Normally the price of the is around $225 or $185 with a coupon directly from the manufacturer’s website.

I paid € 248.99 for the Theragun Prime. On Therabody’s website, the price is listed at $299. At the time of my test, the price in various online stores was around $230. So in terms of price, the Theragun Prime is priced at around $230 to $300.

Accordingly, the massagers are in a similar price range. Nevertheless, I would prefer the Ekrin B37. On the one hand, it is a bit cheaper if you use a coupon. On the other hand, it could score better overall in the other categories.

Conclusion – Ekrin B37 vs Theragun Prime

For me personally, the Ekrin B37 is one of the best massage guns on the market. The Theragun Prime, on the other hand, is “only” in the good midfield. This is reflected in my test results. Accordingly, I would personally prefer the B37 from Ekrin quite clearly over the Theragun Prime.

If you still can’t decide between the two models, the most important differences are summarized here:

1. The attachments differ greatly. Both massage guns are equipped with a ball attachment and attachments for spot massages. The Ekrin B37 also has a flat head attachment and a fork attachment. The Theragun prime, on the other hand, comes with a dampener attachment for sensitive areas.
2. The Ekrin B37 covers a wider range of impact frequency (1,400 to 3,200 rpm vs. 1,750 to 2,400 rpm). In return, the Theragun Prime has a greater impact depth (16 mm vs. 12 mm).
3. The Ekrin B37 is a bit easier to handle, as it has a narrower handle that is also rubberized. In return, the Theragun Prime is a bit lighter.
4. The Ekrin B37 has a longer battery life and a more accurate battery indicator than the Theragun Prime.
5. The Ekrin B37 is much quieter than the Theragun Prime.
