I was surprised how clear the tones are and the bass is insane for these little things

but, I work in a factory high level of noise, these head phones have no bass at all

They sound crisp, the bass is just right

f2f oes lack bass, but that doesn't bother me

Three days ago the bass suddenly stopped working on the headphones, I tried other headphones on my phone and they sound fine

They have a nice deep bass yet very clear

Great bass and sound

but there's even some decent bass to top

Now they are amazing, bass is actually really good too

The bass is very poor, I'm sure if the sound is improve, people won't mind to pay a little more.

Sound quality is good as well - and much better bass than I'd expected

Very loud, awesome bass

Nice bass boost, clear sounds

Nice bass boost, clear sounds

Great bass zero outside noise and always stays in ears.

Very loud, awesome bass

The only improvement I have found is a smoother bass reproduction

Perfect as always
