OK, so using these all day, I struggled with the bass using the HearID combined with accoustic. So I ended up using hearID with my own custom EQ that toned the bass down just a bit. This made instruments like double bass sound more natural.
So I am finding the bass nice but slightly one noted.,the mids are scooped out of the box but can be brought up with EQ.
The treble is a bit strong but not quite as sharp as the L3P.
The GB2P has a much more more forward midrange and treble is almost as sharp. The bass is almost as strong. Detail retrieval on my Samsung Fold 4 is about as good as the L4.
I like the GB2P a bit more but is surrounded kind of sound which some people.might not like as much. It is also alot warmer sounding.
The JBL Live Pro 2 have more recessed mids and the treble is a bit more relaxed than the other 2. The over all signature is a bit colder than the GB2P, it is closer to the L4 in terms of overall signature but has less detail.
Just switched back the L4 and actually they are between the GB2P and JBL for warmth and definitely have better detail than the JBL and I think are better than the GB2P by just a bit.
Fit is more or less a tie between the JBL and L4 with the GB2P just behind the other 2. All are very comfy and no stem with the GB2P so slightly better for sleeping and outside.
I think ANC is close to a draw. The JBL and L4 blocked gym equipment sounds a bit more than the GB2P but the GB2P was a bit better at removing voices. Have not tried ambient enough to have an opinion yet.
The L4 are surprising me, but only after tweaking them alot. But to Soundcore's credit their app allows for lot of customization. JBL does as well but it's AAC limitation holds it back. Samsung on the other hand has very poor presets so you have to like their initial signature to enjoy them.
DHRME say the timbre of the L4 is better than the L3P but still off and I kind of understand why they say that. But I have been able to EQ most of that out.
Hmm, I had Dolby Atmos adapt sound enables and when I turned that off the L4 sounded more relaxed and enjoyable... might need more time LOL.
Anyway will leave this train of thought...
