Ekrin Athletics was founded in 2019 by former collegiate athletes who were looking to share their know-how and experience about fitness and staying healthy.

Ekrin Athletics is based out of Boston, MA, and is “focused on improving athletic performance through muscle recovery and injury prevention”.

As a former college athlete myself and still physically active, I can appreciate the dedication the owners have to promoting healthy, active lifestyles.

In researching their massage gun, I had a few questions about the product which were promptly answered. Customer service is a big issue for me.

Unpacking The Erkin B37

First impression

After researching the Erkin B37, I was excited to see if it was as good as advertised. When the package arrived a few days later, I was pleasantly surprised this massage gun kit was neatly contained in a carrying case.

I have received plenty of massage guns without cases, so again, Erkin started off in the right direction for me.

The Ekrin b37 was nicely packaged within a traveling case with accessories and a charging cord.

Design, Specs, and Features

When I grabbed the Ekrin b37 from the case, I was really impressed with the balance and feel. The gun design had heft but in a good way. It felt solid without being overweight.

One of my concerns with purchasing a massage gun is it has to be user-friendly for my entire family. So ergonomics, weight, and control are very important to me.

Ergonomics, Weight, and Balance

Based on price point, this model falls in the prosumer range. With that in mind, I was curious about the Ekrin B37 vs Theragun comparisons. Before I discuss the comparison data, here are the Erkin B37 specs.

In reviewing the specifications, I was impressed with how well this product compared to higher-priced models. In particular, these numbers really stood out for me:

  • Battery life
  • Noise level
  • Stall force

In regards to features, the Erkin B37 comes with (4) attachments – Fork, Bullet, Flat, and Round. Unless you are a physical therapist, these are the best massage attachments you will use for the majority of your massage treatments.

After giving it time to charge, I was ready to give it a field test.

It takes 4 hours to fully charge the Lithium-ion 2550mAh battery for the Erkin B37. The charge cord plugs into the base of the handle.

If your only exposure to muscle massage is via the use of a hand massager, be sure to proceed with caution.

✔ The Erkin B37 packs quite a punch!

Take some time to acclimate yourself to the speed, amplitude, and impact this device provides at the lowest level, before stepping up to the next level.

I have used several massage guns in the past, but I was very impressed with this device. For this review, I cycled thru to level 3 after a recent workout and that was more than enough for me.

For my test, I used the flat and round head attachments and they provided excellent muscle massaging.

I personally can’t imagine using power levels 4 or 5, but it is nice to know that power is there if needed.

Several other of my family members were anxious to try the massager. Again, their reactions were the same. Great massager, with incredible power.

Besides the power, let me talk about the noise specs for this device. I was more than impressed with the low noise level. Even when tested at the highest level, I was pleasantly shocked by the overall noise performance.

As provided by Erkin, the motor on the B37 Percussion Massager is brushless. Also, here are the decibel ratings at each speed:

Speed 1 – 48.5db
Speed 2 – 49.7db
Speed 3 – 50.7db
Speed 4 – 52.2db
Speed 5 – 54.7db

To give more context to these and other specs, I compared them against top massage guns on the market.

I will let you come to your own conclusions with these comparisons. But the numbers speak for themselves. Prices are another big factor to consider when trying to purchase your deep tissue massager.

My thoughts


  • Love the fit and feel of this device. The rubberized handle offers a superior grip over the average massage gun
  • The travel case is a nice feature not typically seen in this category of massagers
  • Comes with (4) of the most common massage heads you will need
  • The specifications of this device compare and in some cases exceed those of top-rated massage guns in the field
  • One of the best massage guns for any price
  • Lifetime warranty
  • Erkin Athletics is a Boston, MA company with excellent customer


  • Lack of swappable batteries. This is not an issue for 99% of users, since the 8-hour battery life is quite adequate.


Overall, the Erkin B37 provides excellent value when reviewing the specs, features, and cost, as compared to other massage guns in this space. Whether you experience muscle soreness, tightness, and pain from day-to-day life, or you’re a serious athlete seeking pre-workout and post-workout recovery, the Erkin B37 is an excellent choice for each use case.

This device comes complete with a carrying case, massage gun, attachment, and charger. Everything you need to get instant pain relief and muscle recovery at a great price!
