A very good deal with restrictions on the sound neutrality

Per
+ High enthusiasm, dynamic sound
+ Extremely comfortable and very good ear pads (around the ear)
+ Good - very good detail resolution
+ Good - very good spatial representation
+ Stable construction with metal handle
+ Very good bass potential
+ Accurate representation at low, medium and high volumes
+ Good workmanship
+ Very good supply of spare parts by the manufacturer Beyerdynamic
+ No pressure on the ears due to open design

Contra
- Sound not neutral because depending on the volume (and amplifier type) more or less significant exaggerations of heights (S-lute) and the basses are available
- Spiral cable could be a bit longer
- Cable connection to the handset soldered (no plug-in system - difficult changing cables)

Conclusion: if you can live with the limited sound neutrality, gets to the DT-990 Pro a very good headset is fun. Especially in pop / rock / electro (partly Jazz) the neutrality claim is often low or negligible. "Audiophile" or "classical music fans" should listen 325i times a Sennheiser HD 650, AKG 701/702 or a Grado, which are admittedly more expensive. In direct comparison, however, can also act a little "boring" very neutral headphone, also seem to be missing depending on the model (although the original in live concert definitely brings more bass!) The bass.
