Zildjian need no introduction as a cymbal maker and their quality generally extends to their low volume range of cymbals. I have the 13" hi-hats, 14" crash, 16" crash and 18" crash/ride. What I can say is that to my ears, the 16 crash and 18 crash/ride are both really good sounding cymbals. I use the 18 as a ride as opposed to a crash and find that it works really well. The 16 crash is also really easy on the ear, works really well with the set and I love striking it. The 14 crash is arguably the weakest in terms of sound quality, but it has grown on me over time and provides a clear contrast to the 16, making for a nice variety of tones. The hi-hats are an interesting mixture of sounds - I wouldn't say they are fantastic - I find them a little overpowering at times, which isn't something hi-hats are usually noted for, but they do the job and overall these are good enough. The cymbals are surprisingly durable if you look after them, but they do tarnish easily when handled with bare hands. Overall, given that these are primarily for practising rather than performance, I think they are very good for the money and just the fact I can practice with real cymbals as opposed to rubber pads etc, makes them well worth buying. If you buy some too, I hope you enjoy them!
