Boltune BT BH021 Wireless Earbuds- Snug, Secure & Ultra-light

What comes in the box

  • Boltune BT-BH021TWS Earbuds 
  • 6 x Ear Tips (Two are fitted on the earbuds)
  • Charging Case
  • USB-C Charging Cable
  • User Guide

Design & Comfort

Each bud weighs only 0.2 oz. which makes them ideal to be used for prolonged periods and they are not too bulky either. They are a full glossy finish which looks nice but they can get dirty with fingerprints quite easily and each bud consists of LED lights to indicate connection status. You also get a couple of silicone ear tips and choosing the rights ones for your ears will give you quite a snuggly fit with practically no discomfort.

The fact that these BT-BH021 earbuds are super compact also makes wearing these a very pain-free experience.

The charging case is black and has a matte finish that won’t pick up fingerprints and on the lid, you’ll see the Boltune branding which adds to the cool look of the case. The USB-C charging port is located on the side of the case while the LED light indicator is on the front.

The front LED indicator of the charging case changes color to indicate the charging status.

  • The light turns white when the charge is at 75% to 100%.
  • It turns yellow at 50% to 75%.
  • At 25% to 50%, the LED light will turn orange.
  • And, when the battery life is 0% to 25%, the LED light will turn white.

Charging Case

The Boltune BT-BH021Wireless Earbuds sit in their charging case which is magnetized to house them in a secure manner and can be conveniently carried around due to its travel-friendly size. Putting them back into the magnetic charging case is also quite effortless.

As far as battery life is concerned,  these earbuds do not disappoint as they offer 6 hours of use with no more than a single charge and the charging case gives a total of 34 hours which is incredible for how much they cost.

Just 10 minutes’ worth of charge will provide you with an hour of listening time. 

Sound Quality

The sound quality is clear with deep bass and you get ample volume. These earbuds are not exactly noise-canceling instead they are noise-isolating if you choose the proper ear tips for your ears and are able to drown out some noise from around you for good sound quality.

Call Quality

Each one of the earbuds features a microphone to allow phone calls. The microphone quality is poor. Phone calls sound muddy and not clear at all. So, these earbuds do give you the feature to make phone calls but maybe don’t use these for important or lengthy calls.


These wireless earbuds contain Bluetooth 5.2 for a more stable and reliable connection and the range is 65ft maximum.

You can use these buds to watch Youtube videos with and there is not any noticeable lag or delay.

To turn these earbuds on, you just have to take them out of their charging case while turning them off is just as quick and easy, just place them inside their case again and they will turn off.

Conveniently enough, these earbuds can be used not just in stereo mode but even in mono mode.

Also, you can only connect these wireless earbuds to a single device at a time.

Control Features

Touch controls are what you get with these wireless earbuds to operate their features. Here is how you use them:

Tapping the right bud will increase volume while tapping the left bud will bring down the volume, a single tap on any one of these buds will play/pause music, to skip a song you have to tap three times on the right bud and to go back a track you have to tap thrice on the left bud and tapping and holding either one of the buds will activate Voice Assistant.

To answer a phone call, you have to tap any one of the earbuds only once.

To hang up a phone call, you have to tap either one of the buds twice.

You can tap and hold either one of the earbuds twice for two seconds to reject a voice call.

Water Resistance

The Boltune BT-BH021 TWS Earbuds are great to use when you are out and about as they feature the IPX8 waterproof rating which protects them from harm from rain as well as sweat.

This also means you can make use of these at the gym during intense workout sessions as well.

ANC ( Active Noise Canceling Technology )

Choosing the silicone tips that fit perfectly into your ears will give you the best passive-noise cancellation.

Brand Credibility

Boltune is quite popular and is one of the many brands out there that produce cheap True Wireless Earbuds and other audio products like wired headphones, etc.

Boltune was founded in 2018. They have since made a name in the arena of audio products. 

Their website states:

 “ We focus on easy-to-use Bluetooth earphones with high-quality audio sound. With TWS earbuds you can listen to your favorite playlist wirelessly or freely share music with your loved one.” 

The Boltunes website also features a catalog where you can view all of their product range like their true wireless earbuds, and their wireless headphones, etc. 

Quality & Materials Used

These wireless earbuds are made of plastic and very light but not low quality. The charging case is also plastic but, it feels robust and not fragile either.

The charging case lid, on the other hand, seems to have a flimsy hinge that keeps it from staying put when opened. For their price, these earbuds are of decent quality.


At the time of this review, the Boltune BT-BH021 TWS Earbuds are priced at $56.44.
