Clean, warm, smooth yet solid detail high-end vibe cans

5 stars considering I snagged these cans on sale for less than $80. I own HiFiMan 400i, Sony MDR-1A, Sennheiser 599 & 558, Status Audio OB1 & CB1 & BT1, and Klipsch on-ears(forget the model) among several others, mostly budget that perform well above their price points such as Anker Soundcore, Tribit, etc. The Monlith M650s are my favorite overall. I love the sound signature. I’m guessing it’s a subtle U(not completely flat and definitely not V). Being open-back and not overly especially colored bass is not overwhelming yet it’s prominent just enough and it’s real. Smooth, perhaps sliding off a bit at the lowest levels. Personally I like it. Mids are fantastic and the highs are just above a flat or completely neutral sound line. But they are smooth for treble too, not grating or super bright. As with the bass I would say the top of the highs are soft but again I like that with these cans. Overall the sound is very clean yet pretty damn warm. Seriously I feel this pair is easily competitive with $300 & less headphones. So even at regular price they’re a decent deal. On sale they can be a steal.
