Great earphones

I have small ear canals these IEMs actually fit my ears! They sound great and are affordable. Nothing to complain about so far.


It's a great IEM for not a lot of money. Many will consider this to be perfectly tuned. Personally I think it is slightly too bright, but I am very sensitive. The design and fit are also great. It's a perfect complement to the Blon with a more Harman like tuning. If you didn't like the Blon this is also a great option.

An Absolutely Great IEM!!!

A really awesome IEM for the price, it has a good solid base that thumps yet is controlled nicely, and it doesn't bleed into the mids. The mids and treble are well balanced with a sparkle on top, but no semblance to my ears, vocals are only a tad bit back, and are clear and crisp, with a minimalist of dryness. A fun pair of IEM's with emotion. Did switch out ear tips to foam, and am using the Shozy Form 1.1 cord for these, makes them look really nice, and these are a beautiful pair of IEM's that pictures just don't seem to show. Quality is also very good. The flow from low to high and back is seamless, a very good job tying it all together. And I do like these more than the Shozy Form's, just more sparkle to them, that adds a bit more of delight to my listening pleasures.
