Audio in Your Ears That Surprises a Lot

The Moonki Sound line has more and more products aimed at the general public. This time, we tested the MH-TWS33, ideal for when we're in the concrete jungle.

Opening the MH-TWS33

The box is standard. We opened a lid and found a pill-shaped charging case with an internal battery, the earbuds inside, and a USB-C charging cable.

The earbuds are compact and completely independent from each other (there are others that have a band to link them), and they are in-ear style, meaning we have to "fit" them into the ear. To help with the fit, they come with highly adaptable rubber tips that provide a surprising level of grip and isolation... so much so that it doesn’t come with multiple tips; the one installed can work for all ears.

The MH-TWS33 in detail

Each earbud weighs only 5 grams, almost the same as Apple's AirPods, which weigh around 4.5 grams, so the comfort is very good. Each one has a multifunctional touch button that, depending on the moment, can operate as power, answer a call, hang up, etc.

The speakers are 8 millimeters in diameter and have a frequency range from 20Hz to 20KHz, according to the manufacturer. The internal battery is 30mAh, providing a continuous usage autonomy of 4 hours and up to 120 hours in standby.

Additionally, it incorporates an omnidirectional microphone that works as a hands-free device for your phone. We tried speaking through it, and on the other end, they always said the audio quality was very good, even while talking in city traffic.

It is used wirelessly via Bluetooth. Pairing is simple: take the earbuds out, wait 2 or 3 seconds for them to pair automatically, and then pair the Bluetooth without any major issues.

What’s the deal with the MH-TWS33 charging base?

It has a 400mAh battery that now allows you to charge the earbuds 3 times before it runs out. The downside is that it doesn’t have a charge indicator, so you can't tell when it’s time to recharge the unit. The battery is charged via a USB-C cable, and the charging time from 0 to 100% is about 2 hours. The earbuds go from 0 to 100% in 1.5 hours.

Testing the MH-TWS33

How do these earbuds sound? Since they are more of a "street" type earbud, we only analyzed the usage and music aspects.

In terms of use, I found the MH-TWS33 extremely comfortable, and that’s saying a lot since I usually struggle with in-ear earbuds. The silicone foam tips isolate sound very well and are comfortable to use due to their light weight.

In terms of audio, as a retired DJ, I’m very picky about audio quality, and I have to say I was really impressed with the very balanced frequency range. The bass sounds full (not all in-ear headphones have good bass, as we know), and the mids and highs have very good resolution, even at somewhat high volumes when we’re on the street.

Conclusion

The price of the MH-TWS33 is quite competitive, coming in at approximately $3,900 pesos in the Argentine market. When compared to similar options, like the Xiaomi Redmi Airdots, which fall within the same price range, or the Galaxy Buds, which are much more expensive, the MH-TWS33 offers an excellent balance of performance and cost. For the price-to-performance ratio, these earbuds truly deserve a Gold Medal for delivering impressive sound quality, comfort, and reliability at an affordable price. [IRROMPIBLES]. [i]
