What you need to know about the Beyerdynamic DT990 Premium (600 ohm version)

The build

The DT990 Premium features impeccable build quality, and superb comfort, especially for extended listening sessions. They look and feel like high-end headphones.


The sound


These are open headphones, and leak sound significantly. All Beyers have a V-shaped frequency response curve. In general, the DT990 has the most V-shaped curve when compared to the DT770 and 880, with prominent bass and a somewhat bright treble.

The 600 ohm version of the 990 Premium follows the same general rules, but its bass is a little less prominent, most likely because of the reduced clamping force. The low end is controlled, and if you amp them appropriately, nice and tight.

Mids are neutral, vocals are well represented without tonal distortions or coloration.

It has the same 9000 Hz spike as the Pro version, and so if you are not a fan of tinkly treble then most likely the 990 premium will disappoint.


FAQs


Q: Does the Dt990 600 ohm premium need an amp?

A: Yes, it will benefit from an amp. You don't need a monster like the Schiit Lyr to power it, though. The most noticeable difference with a good amp will be tighter bass. Some mobile devices like phones and tablets will struggle to run the 600 ohm DT990


Q: Whats the difference between Pro and premium DT 990 versions?
