Every day, a new pair of earbuds hits the market, making it hard to tell the good ones from the bad ones. Price segments help us break up the confusing market into pieces that are easier to understand and compare, but the sheer number of goods on the market makes it hard to choose just one.
Many cheap brands make great buds at prices that are hard to beat. Still, there are trade-offs to be made whether you want top-of-the-line TWS earbuds or cheap, happily wireless earbuds that appeal to people with less money. Tronsmart has a wide range of audio tech for both high and low prices, and we have tested many of their products in the past. We haven’t seen anything from this brand that looks like the Tronsmart Onyx Ace Pro earbuds.

Tronsmart Onyx Ace Pro: Design and Build

In the last few years, almost all of the wireless earbuds I’ve tested came with pill-shaped charging cases that didn’t have much decoration on the outside. Tronsmart must have grown tired of this simple design, because the Onyx Ace Pro has a silver trim around the flip-top opening and a silver panel on the front with four lights that show how much charge it has.
It’s a little tricky to open the box and get the buds out, but once they’re out, they look like Apple AirPods. There are no rubber ear cups to keep them in your ear canal. Instead, they have smooth plastic ovals on short stalks that rest against the holes in your ears.
Tronsmart Onyx Ace Pro: Sound Quality
We have no trouble being heard by one another, and we can even understand the person who is going to call us because of the high quality of the mics. The headphones’ noise reduction feature effectively muffles ambient noise so you can focus on your call. In other words, we can listen to music while on the phone without having to remove the headphones.The IPX5 standard guarantees protection from water, even brief contact. When the power is low, you can use one headset while the other charges. You can buy this earbuds from its official website
Tronsmart Onyx Ace Pro: Performance

Podcasts that have quieter or more realistic sounds work much better, and the sound is very clear. It’s the same with phone calls. We haven’t had any problems with how the Onyx Ace Pro earbuds work when we talk to friends and family or take the odd conference call. No one complained about noise or muffled mic output, so it seemed like both parts of the conversation were fine.
Tronsmart Onyx Ace Pro: Battery Life
In terms of battery life, these have to be some of the best buds we have tried. The buds can last for more than six hours on a single charge in the case before you need to put them back in to charge again. Even though it takes more than an hour to get them back to 100%, we are happy to pay that price for the long listening sessions they offer. Tronsmart doesn’t say how big the batteries are in the buds or in the charging case, but the case isn’t a loser either. After a full two-hour charge, it has enough power to charge the buds about five times. Putting in a total of 36 hours is a good thing.
Price and availability
The company also told me that these should be on Amazon soon, but as we write this, we can’t find them anywhere. If you look at the competition, the Redmi AirDots, which can be bought on Amazon for £25/$25 and have most of the same features as the Onyx Ace Pro, are the most clear alternative. If you want noise-cancelling headphones, you’ll have to spend a bit more, but the Redmi Buds Pro 3, which cost £65 on Amazon UK and $59.99 on Amazon US, are an excellent choice.
Final Words
Tronsmart lives up to the second part of its name by making a good pair of wireless earbuds that sound good, fit well, and have a long battery life, all for a price that most people can afford.
If you’ve been hesitant to move to wireless earbuds, these would be a great place to start. You can always upgrade to a pair with active noise cancellation later on without feeling like you’ve wasted your money.

FAQS
Even though they can handle the heat of indoor training, they are very difficult to keep in your ears when they are wet, and even though the sound quality is good, they feel pretty cheap overall. The Onyx Ace Pros have a battery life of 6.5 hours and look a lot like Apple’s AirPods.
Tronsmart was started in 2013, and its headquarters are in the middle of Shenzhen, which is known as the Silicon Valley of China and is one of the most technologically advanced places in the world.
