for me A-B testing with o-k studio speakers and my t14s gen2 speakers
Compared to my nice speakers the bass isn't *deep* and the highs are overblown, especially in snares. The sound stage is muddy.
Compared to my thinkpad speakers, the bass is deep and the sound stage is relatively great 
(mostly using Tame Impala - Currents as a sample and hip hop)
