Pros: Clear sound, very big soundstage.
Cons: Bass boost.
A friend of mine needed a new headphone, which was cheap, closed and good sounding. I said to him, dream on friend it will be very tough to find a headphone with those criteria.
But then after some browsing in the city, I stumbled upon the philips uptown. The first thing that struck me was the comfort. They feel much better than what you would expect for the price. I thought they felt better than the sennheiser momentum with those small ears. After I turned on some music I noticed the soundstage, it is very big for a closed headphone. I think it even rivals the Beyerdynamic DT770 pro, on that matter.
Other than that, the sound is very clear, and apart from the boosted bass it sounds very even and pretty neutral. All the frequencies are very clear sounding and the treble is nice and sparkly without any sibilance. The bass is boosted though, and bleeds a little in the mids. But it is very tolerable, and when using this headphone in noisy environments the bass sounds far less boosted.
All in all: Very clear sound, with big bass for extremely little money. This headphone can easily rival closed headphones in the €150 range, especially if the used DAP has a -1 bass function!
