Tronfy iWork Mini vs Rowkin Mini

This earpiece costs 1/5 of the others, while still offering a decent experience.

The rear plate is a physical button which can call the previous contact (double tap) or activate Siri (long tap) as well as a single volume button (5 levels - it cycles through from low to high and then back to low)

Using just the one earpiece you can expect around 3.5 hours of battery life of continuous music playback. This time will be reduced slightly when making calls, however when compared to its competition it's a very decent result.

More than just different sized caps are included - you get two different styles of caps in multiple sizes. In addition, there are removable clear plastic clips that clip onto the earbuds to help keep them in your ear. These clips also come in different sizes, and are ideal when working out or moving around often when regular earbuds would have a hard time staying in your ear.

Included is an attachment that has a wire and an additional earbud. Plug the wire into the primary (larger) earbud, and you effectively have stereo bluetooth earbuds. It's your choice if you prefer to use the single earbud, or the pair (although the single earbud will provide longer battery life).

Instead of using a proprietary charger, there is enough room to include a fullsized regular micro-USB charging port on the earpiece. This means that there are plenty of affordable cables available if the original is too short or gets lost/damaged.

It's amazing how compact the earbud and portable charger both are. The diameter of the earpiece and charger are both considerably smaller than a dime. The earpiece itself is about the same size as regular wired earbuds, which is amazing considering that it has a battery and charging elements tucked away inside.

The speaker inside provides good, clear sound that gets sufficiently loud without sounding tinny. It can be used to play music, take calls, and more with no issues. The bass is slightly lacking, but that isn't surprising given the price and minuscule size.

The earbud magnetically connects to the portable charger and charges wirelessly. This keeps the design of the Rowkin Mini nice and clean, and also is convenient because you don't need to use a cable. The portable charger itself can hold enough juice to top up the earbud 4 times before needing to be recharged itself, which of course needs to be plugged in.
