As the name implies, you can charge the Avantree TWS115 True Wireless Earbuds wirelessly, and they also have a heavy bass response. Plus, they cost less than $50, which is a steal!

Here's What We Like

  • The sound is good (and bass-heavy) for the price
  • Pairing is surprisingly easy
  • Solid battery life
  • Wireless charging is rare at this price point

And What We Don't

  • They feel cheap
  • Controls are uncomfortable to use
  • I'd trade wireless charging for a thinner case or better sound

This isn’t to say they’re perfect. Again, they’re less than $50, and they do feel that cheap. They’re super lightweight (which isn’t necessarily a bad thing), they aren’t sweatproof, and I have some problems with their controls (more on that later).

However, the TWS115s managed to surpass some expectations—at least those I had for wireless earbuds at this price point. They’re fairly comfortable (again, lightweight), they sound good, they have a solid battery life, their case is genuinely portable (it’s only about three-inches long), and you can charge them wirelessly (without blowing them up). What more could you ask for?

What’s That? Bass Boost?

Earbud sound quality is pretty hit or miss, especially when you dip into the cheap wireless variety. However, I’m happy with how the Avantree TWS115s sound. They aren’t perfect, but they sound adequate for the price (and maybe better than some competitors).

These earbuds emphasize the bass and treble frequencies. In fact, they offer a prominent bass boost you won’t find on other budget wireless earbuds, like the TaoTronics SoundLiberty 53 True Wireless Earbuds. Is that a good thing? Not necessarily—bass boost can make music, podcasts, and videos sound muddy. However, it’s better than just treble.

Speaking of treble, I’m impressed by how the high end sounds on these earbuds. It’s crisp without getting into that aluminum-on-a-chalkboard territory, which is surprising at this price point. The Avantree TWS115s are definitely worth a look if your current earbuds attack your ears with piercing treble and no bass.

My one real complaint about the TWS115s’ sound quality is the same one I have about most earbuds (including AirPods, Jabras, and so on)—there are no mids. Without mids, music sounds thin, voices sound distant, and kick drums lose their oomph!

However, I won’t knock off points for this.

Solid Bluetooth, but Underwhelming Controls

The earbuds automatically connect to your phone when you pull them out of their case and automatically disconnect when you put them back. I haven’t encountered any lag, they haven’t fallen out of sync, and the Bluetooth connection works flawlessly across the length of about two bedrooms.

However, the controls are kind of annoying. They’re not complicated, but you have to push really hard to get them to work. I don’t tend to like having to aggressively press an earbud against my ear hole—it’s just uncomfortable.

I’m also bummed there’s no volume control on the TWS115s. Although, to be fair, I’d rather adjust the volume on my phone than push down on these things while they’re in my ears.

36 Hours of Playtime Ain’t Too Shabby

The TWS115 earbuds can run for about four hours before they need to recharge in their case. That’s not amazing, but you do get an extra 32 hours from the charging case, for a total of 36 hours of playtime. Like other earbuds, you can check battery life from the Bluetooth settings on your phone.

That’s pretty great for a pair of budget earbuds. For reference, the AirPods have a 4.5-hour bud life and a total life of 24 hours. (If four-hour bud life is way too short for you, check out the Creative Outlier Air True Wireless Earphones—they have a 10-hour playtime).

As for charging, it’s what you’d expect. The earbuds take about 45 minutes to charge. The case charges in about two hours via micro USB port or wireless charging. Wait, wireless charging?

I’d Trade the Wireless Charging

I’m really surprised these earbuds not only support wireless charging but also that they don’t overheat while doing so. Aside from AirPods, most wireless earbuds lack wireless charging capability and force you to use a USB cable.

While I like wireless charging (and appreciate that I can skip this thing’s micro USB port), I’m admittedly a bit confused. Maybe there’s a reason why other $50 earbuds don’t have wireless charging, you know? Maybe the cost of wireless charging hardware (and the space it takes up) could be used for something better, like a bigger battery, a thinner case, better buttons, or more robust sound.

I’m not downplaying the wireless charging feature. It’s a neat luxury, and I can see why it might be a selling point for some people (it’s certainly made things easier for me). I just think the TWS115s could be a better product if that manufacturing cost went to something more rudimentary.


All in all, the Avantree TWS115s are a great pair of budget earbuds. They feature a high bass response, solid battery life, and wireless charging (which I consider to be a luxury).

The only problems I had with these earbuds are the build quality and the controls. I also wish the cost of wireless charging went into something more basic, like better buttons or more battery life for the buds. However, these flaws are pretty easy to overlook when you consider the TWS115s price tag and features.

I’d recommend these earbuds to anyone looking within the $50 price range—and if you find them on sale, definitely buy ’em!
