Light song man IE8 titanium film Horn High Fidelity IE6IE7,IE8,IE80 turbine copper shell and other 10mm earplug unit

This is the second time I bought this unit, first of all, let's talk about it, this is much worse than the 9.2 beryllium film...... 🤭 , after all, the price is only half that of that. The basic quality of this unit is still very good, but it may not be suitable in the IE80 shell, the back cavity of this shell is almost open, this unit is a little uncontainable, plus I haven't installed it yet, I tossed it for many days, and I didn't make a very ideal sound, the 9.2 unit came out with a good sound, 😀 and now I bought 10 more, try a few more shells to see, although it is not ideal on my IE80 shell, I don't think it's a problem with the unit, it's a matching problem, I feel that this is suitable for a case with a small rear cavity and a complete seal. The bass dives well, the mid and high notes are average, I didn't tune it out, I'm going to make a circle iron to see. The sound field analysis is good

There is nothing wrong with Lao Zhou's things, the flat head has not been made yet, and it is good in the ears. Very good, very good.
