The Sennheiser HD 400 Pro is the best Sennheiser headphone I own. The sound is clear with great definition. The vocals are awesome. Instruments are easy to pick out of the mix. The sound seems natural with plenty of low end. So far I haven't detected any distortion. I bought them for listening but they might be great for mixing as well. The only complaint is they are tight on my head. After two-hour sessions, I didn't experience fatigue. I wanted to keep listening.

These are an amazing set of headphones and are a steal for the price. The build quality is great for being an all-plastic construction. It comes with 2 cables: a straight one and a coiled one both terminating in a 3.5mm audio jack. The cable end which goes into the left headphone cup is a proprietary connector. Both are great stock cables with no micro-phonics while playing audio. The sound is balanced and they are not hard to drive. They are easily powered by my laptop's 3.5mm audio jack. I will be testing them with an AMP/DAC combo and will update my review regarding how they scale with amplification. They are amazingly comfortable and offer an amazing sound for casual and critical listening. 10/10 would recommend. Edit: I received my DAC/AMP combo (Topping DX3 Pro Plus). The HD400 Pros have scaled amazingly well with the amplification and have benefitted immensely from the clean signal coming from a quality ESS chip inside the DAC. I was unsure about the gains that I would be getting from the DAC/AMP over the laptop jack, but after using it, I am completely satisfied with my purchase. It has been an eye opening experience.

Great for my application (home recording/mixing studio). Open back design results in more accurate sound without the "cuppiness" of closed back designs.
