First I want to thank the Seller for the support as always in telling me about new products. As for the EPZ this was my first contact and what a pleasant suprise. The IEM is gorgeous, with a solid construction quality. The supplied tips are quite good although for me I had to use different ones....big ears As for the sound , it's good, really good, it's the kind of earphone you can keep listening too for hours, it's for warm sound and everything just sounds smooth....at least with the music I listen too. perhaps there could be a little more detail and sense of space but otherwise it's a fun earphone and easy to please everyone. definitely will buy more EPZ products as of their budget is this good , I will be curious to try the more expensive.
