If you are looking for an affordable, warm sounding TWS headset with good bass Mpow M7 is for you.
I like warm sounding headphones/earphones with emphasis on bass. I was using Sony MH1 with my phone for a long time, they sound warm and produce good bass. After a month of searching, reading reviews, especially on Amazon Japan, I decided to order Mpow M7.
Tried comparing Mpow M7 & Sony MH1 on many different songs, I can say that Mpow M7 sounds warmer, and it produces a bit more bass than Sony MH1.
You can use MH1 eartips too.
You should cut eartips with scissors a little & make it smaller, with MH1 eartips now it's more stable in the ear, sound quality also improved a bit.
Other than sound, connection quality and connection distance is really good. It connects to the phone instantly.
Couldn't find a song that sounds odd with this headset so far, I think they are tuned well.
A few things:
Volume level is high.
I used middle size eartips and it is not very stable.
Comes with 3 size eartips.
Do not use fast chargers.
Battery life is 5-6 hours.
