Truly wireless earbuds sell like hotcakes among headphones.
Since Apple Inc. rolled out AirPods—the forebear of TWS (True Wireless) headphones, many people have abandoned their troublesome wired headphones for the truly hands-free gadgets.
True wireless earbuds can help get rid of the constant annoyance of wires, making sports more enjoyable.
For those who demand maximum portability, true wireless earbuds are right for you.
But it is not easy to find well-built items from the immense varieties of truly wireless earbuds.
After hours and hours of research covering different earbuds from myriads of brands, I can confidently say the following two TWS Bluetooth earbuds can provide you with high-quality wireless music experience for under $50: Redmi AirDots TWSEJ04LS and i12 TWS Binaural Call Bluetooth V5.

If you're in a hurry and want to see the merits for each product, check out the specs below:
Design (appearance, convenience, comfort)
Redmi AirDot's charging box comes in oval while i12's comes in case shape.
The Redmi AirDots headphones I am reviewing are a nice classy pitch black and look like two small dots, with its body made of ABS (Acrylonitrile Butadiene Styrene) material; while i12s in-ear headphones are made from glossy white plastic.
Although their build qualities are both satisfying, Redmi AirDots –thanks to its color and oval shape– might be more attractive to those who hunt for good-looking gadgets.
However, i12 might fit for those iPhone die-hard fans, for i12 TWS earbuds look similarly to AirPods.
Besides, i12 is more built for iPhones (I will talk about it later).
Both headphones are small and highly portable.
The size of the Redmi AirDots charging box is 62 × 40 × 27.2mm, with the only 0.04kg, which means you can put the whole set in your pocket and carry it around without any trouble.
i12's charging box weighs twice more than Redmi: 0.08kg, but with a smaller size of 54mm × 44 × 15mm.
As for the weight of a single earbud, Redmi AirDots features 4.1g while i12 weighs slightly lighter. But you won't feel much difference.
So in terms of convenience, both headphones would not be a heavy burden.
Plus, the charging boxes of both headphones are equipped with a Micro USB charging port.
Both are convenient to charge, and earbuds will not easy to fall out of the cases with the help of magnetic contacts. Just put the headphones in and they will automatically start charging.
What's more, there is a charging indicator on the Redmi AirDots' charging box, a bonus to its credits.
Both are true wireless, namely, no wires wing between your earbuds.
However, Redmi AirDots are soft for a comfortable fit, in comparison, i12s headphones are hard and sleek.
Redmi AirDots is ergonomically designed and comes with four sizes of soft and comfortable silicone ear caps for better closure and firmness, so they won't drop off even if you listen to music when running fast on the treadmill.
Some may feel itchy when using silicone in-ear earbuds for too long. Personally, I am more comfortable with plastic earbuds if I don't use them during exercise.
However, one potential problem with i12 may be the sound leakage, due to its sleek design. You may get distracted with people talking nearby, or when the volume is high, you may affect others.
One more special feature about Redmi AirDots in-ear headphones: it is fit for sports. It claims to be a sports headphones. Plus, it is more of a Bluetooth running accessory with its anti-sweat design.
Winner: For good appearance hunters and sportswear lovers, choose Redmi AirDots
Now for the most important part, the sound quality.
Redmi AirDots feature high-speed DSP digital noise reduction technology, offer you softer and clearer sound quality and good call quality.
Redmi AirDots also features a bilateral call function. Even in the busy street, you can enjoy high-quality phone calls.
i12 TWS Bluetooth earbuds aim bigger with its noise-canceling function, high-fidelity sound reproduction, and stereo sound quality.
Both are perfect choices for listening to Bluetooth music streaming outdoors.
But you should also note that true wireless earphones perform worse than wired earphones, so you can't expect a flawless bass from earbuds in this price range.
For non-audiophile, it's enough.
Performance (battery life, connection, control)
The Redmi AirDots Wireless Earbuds come with a 300mAh charging dock that delivers 12 hours of power and can achieve 4 hours of music time when using headphones alone without a charging box.
Similarly, i12 TWS earphones also provide a better capacity up to 300mAh, with 60 hours of standby time. But its music/call time is shorter, 1 - 3 hours as it claims.
Both support Bluetooth 5.0 technology and are widely compatible with various Bluetooth devices with a more stable connection. The transfer rate of Redmi AirDots is 200% faster than the previous generation.
Both i12 and Redmi AirDots can trigger AI voice assistants including Siri from your phone to perform tasks.
Both headphones are easy to use for the first time.
Just choose the name of the headphones on the mobile phone and pick up the headsets to use.
But it seems to me that the Redmi AirDots Bluetooth headset is relatively simpler to operate. A single click for pausing songs and double-clicking for waking up the Voice Assistant such as Xiao Ai smart assistant and Apple's Siri.
For i12, you need to control the touch time.
One gentle touch for pausing music and 2-second touch for volume up and down and 3-second touch for switching songs.
The bummer is i12's volume control is only available on iOS, not Android. As I mentioned before, i12 is more suitable for iPhone users.
Winner: Redmi AirDots
In general, these two true wireless earbuds (TWS) are nice choices for the best value for money.
Both have great build quality.
But if you want to use headphones when jogging, Redmi AirDots would be way better than you'd expect.
The earbuds are more secure and fixed in ears due to the ergonomic design.
For iPhone fans though, i12 may be a wise choice for those who want a way cheaper price and similar products like AirPods. i12 can totally satisfy the daily calling and entertainment needs.
