Pros
Overall very pleasant balance with good tonality and perceived technicalities for the price.Cons
Bass can come off slightly boomy and a bit disjointed sounding at times, and somewhat relaxed upper mids gives a perception of bluntness to the sound, most evident on snare and other percussive strikes.EPZ P50 User Reviews
