      Good bass IEM

      Even though this is slightly older or released couple of years before, still good. With eartips changed, the bass improved a lot. I used Soundmagic eartips and spinfit cp100 and observed the bass improved a lot. The cable is basic one and could be used for some time

      Value for money

      Sound is good but definitely not to everyone’s taste. Highs can get a little piercing. Not the best fit. The wire feels very weak. Other than that it is a great earphone for the price.

      Budget IEMs

      HiFiNage has exchanged Astrotec AS-200HD and gave me KZ ES4. So first of all, below is the experience of Astrotec AS-200HD and HiFiNage:

      Actually I liked the product. But the product soft skin was peeling off when I received the item. I informed hifinage support. I really loved the way they responded to me to issue a store credit note to purchase another item. It was a master class service from them. I really recommend all the products to purchase what they are selling. They are very lovely and much more responsive and responsible. Loved to purchase at hifinage.
      Warm Regards

      Now the review of KZ ES4:
      ES4s by KZ absolutely does their job. They are very balanced in-ear monitors for beginner audiophiles. They are perfect with foam tips for better fit and noise cancellation. Recently downloaded FiiO music app. These IEMs are doing good with that music player. One comment on Hifinage is They are very much responsive and Responsible. Really loved the support they extended when I required for a defective piece. Just choose any product and Trust them they will do rest till you receive the one. Warm Regards
