After about a week of listening to the Temperament DB1, here's my impressions. I've been wearing them with the provided full foams and over ear hook style instead of cable hanging down. It was already reported by
@omerad (in
post 68,697) that they sounded better when worn over ear versus cable down and I can confirm that. The bass and lower midrange presence is much better when worn over ear. In contrast, the sound appears to lose some of the nice bass, lower midrange timbre when worn cable down. I guess the sound difference might be useful for different types of music or to suit your musical mood.
My first general impression is that they have a balanced warmish sound with some boost in the midrange. I can't really put my finger on it, but the midrange has this sort of transparency that draws you in, like you're not wearing any buds. We'll have to wait for
@JAnonymous5150's impressions to see if he's hearing the same sort of thing.
The low end is very good. While not in your face, the bass / upper bass have this nice body filling timbre which I like. Going to the opposite extreme, the treble is smooth, yet detailed. Definitely not lacking in resolution or having treble roll off.
The only comparison I'll make is with K's LBBS buds. If you have the LBBS, then expect a somewhat similar K's family sound signature with enhanced low end. I don't think you can just EQ the LBBS to sound like the DB1 though.
Would I recommend the Temperament DB1? I would. If you already have the K's LBBS and like how they sound, then the DB1 is in the same wheelhouse and definitely a step up in performance.
The burning question is how do they compare to the lower cost DB1e? We'll have to wait for
@JAnonymous5150's DB1 vs DB1e comparison.
