I've owned some other Sennheiser headphones like the HD 595, and those have great sound, but it really demands running the headphone from a 1/4 inch jack, since your acoustic experience is not nearly so isolated, and there's a lot of bleed

I used this on my galaxy s4 and i can get a good listening experience without cranking it up to its loudest.

Like I said if you need more accuracy for this price range check out the DT770's but for an overall better experience these for sure

Great customer experience with the seller also.

Only downside is it needs some power to have a good experience.
