Made for workouts
While active noise cancelling is a feature you might want on a pair of earbuds, it's not nearly as useful as a heart rate monitor when it comes to using it for working out.
Amazfit's first earbud, the PowerBuds, features a heart rate monitor similar to the ones on fitness watches i.e. a ppg heart rate sensor that uses light on the skin and measures changes in its absorption, which relates to the rate of blood flow as controlled by the heart’s pumping action.
To get the most of your workout, you can set your maximum heart rate and get voice notification when it exceeds that value.
Also, there's no need to worry about sweat or rain because the PowerBuds are IP55 rated water resistant. An IP55 rating essential means the product is protected from water sprays from all directions.
Stored inside the PowerBuds' charging case are two earhooks that attach magnetically to the earbuds to make sure they don't fall off during aggressive movement. The earbuds can still be used without the earhooks if you prefer for normal use.
There's enough power to last you a whole workout and more. The PowerBuds has a battery life of about 8 hours on a single charge with heart rate monitor turned on. In comparison the Airpods Pro has a battery life of 4.5 hours on a single charge and the Sony WF-1000XM3 can last 6 hours (with noise cancelling turned on).
The PowerBuds' charging case adds another 16 hours of playtime for a total of up to 24 hours. 15 minutes of charging (USB-C) can add another 3 hours of battery life with heart rate monitoring turned off.
The PowerBuds does not have noise cancelling but according to Amazfit the sound is immersive and dynamic thanks to its high-sensitivity magnet and composite diaphragm.
There's also something called Motion Beat Mode that enhances bass and make music sound clearer and more powerful.
If you're outdoors and you don't want the immersive sound to block out the surrounding sound for safety reasons, there's Thru Mode that enhances ambient sound while you listen to music.
You can also configure the PowerBuds to automatically pause whatever you're listening to when you take it off and resume playing when you put it back on without messing with buttons. However, you can still pause without having to take off the PowerBuds by tapping or double-tapping on the earbuds depending on how you set it up.
As for call quality, the ENC dual-microphone noise reduction technology should make calls clearer by inhibiting ambient sound.
At about $99 for the PowerBuds, it is quite cheap especially for what it can do. It has a heart rate monitor, which absent in most earbuds but if you already have a sports watch that can already do that, the heart rate monitor is redundant. Also, the battery life is comparable to if not better than some high-end earbuds with a premium price. There's no active noise cancelling though, but still for the price and features it's hard to say the PowerBuds in not a good buy.
