The Signature DXP came out several years after the Signature PRO and DJ, and comes some cosmetic changes between it's older siblings. Ultrasone removed the glass side inserts , and changed the real leather to pleather for the DXP. Aside from cosmetic changes they altered the tuning of the headphones to strike a balance between the PRO and DJ's, and in this they greatly succeeded. The DXP takes almost all of the strengths of the PRO & DJ's, while nullifying their biggest weaknesses (slightly thin low mids on the DJ, and a smaller sound stage on the PRO). This is all achieved with nearly the same level of detail as it's older siblings.
A quick breakdown is:
- Sound Stage: DXP has a wide, but not too wide, sound stage. All of the instruments and vocals sound correct, not too spread apart and not too confined.
- Bass: The DXP hit's hard and clean. The bass amounts and textures are slightly less than that of the DJ, but overall it is similar.
- Mids: The DXP sounds similar to the Sig PRO with full mids that carry voices and instruments with emotion and power.
- Highs: The DXP has a smoothed treble, similar to the Sig DJ, with an accent at the top of each note that makes the treble sparkle. The highs are never harsh or too much.
- Comfort: Despite changing the leather padding for pleather, the comfort is surprisingly good. The headphone won't shake off easily with head movement, and also doesn't push too hard at the same time.
