Kiwi Ears Belle

Best one yet

Cheap and good quality

Kiwi ears belle after few months

Those iems sound really really nice mid tones are good and bass sounds really warm and juicy although they are starting to play quieter on the right side and it messes up the quality idk what caused this issue.

Dear Customer,

We are very sorry to hear that you have encountered this issue.

To help us better identify the cause, could you please help us check whether the filter is clogged?

A sound imbalance issue is often caused by a clogged filter. Please carefully use a small needle or a suitable tool to remove the filter and clean it thoroughly, then test the earphones again to see if the issue can be resolved.

In addition, could you please try swapping the left and right sides of the cable to check whether the issue follows the cable or remains with the same earbud? This will help us determine whether the problem is related to the cable or the IEM itself.

We have also sent you an email to follow up on this matter. Once we receive more information from you, we will do our best to assist you and work toward a proper solution.

Thank you very much for your patience and cooperation.

Quick Review

These are very interesting IEMs; the sound quality has a V-shaped curve, they're comfortable to wear, and suitable for extended listening sessions. However, there are still many competing products in the around $30 price range. and the experience of opening the box was less than satisfactory, it didn't come with a case either, but overall it's good.
