Not my first soundpeats product but this one by far is my favourite. The fitting is perfect, the 'wing' thingy keep it nicely in my ear without make it too uncomfortable. The sound quality is great - balance and not super basey. I am not audiophile, but i can say it is definitely decent enough for everyday use.
The case is - big/heavy that may be a disadvantage if you want to carry it in your pocket .It has a 3000mah battery in it, to be honest it's still too small for a powerbank but i guess it's ok to use as emergency.
Overall for 50ish dollar you can't go wrong with this!
