Many music lovers, when listening to songs with in-ear headphones, may pay more attention to the sound quality of the headphones themselves. Ignoring the role of the silicone sleeve, choosing a good silicone sleeve will greatly improve the sound quality, tone, and other performance of the headset. The special metal silicone housing provides a rich, quiet, and rich bass, which improves the bass feel of the headphones. At the same time, it can effectively block excess noise and improve the wearing comfort of the headphones. Ultra-soft special silicone, imported material is stronger, will not cause sound fluctuations due to ear canal deformation, suitable for 99% of earbuds and headphones. Using inferior silicone sleeves, the high-pitched sound is high, the bass is slightly imaginary, and leakage occurs. After using a good silicone sleeve, the bass becomes very real, the leakage phenomenon is gone, and the treble is reduced, so if you are not comfortable with the bass of your headphones, don't forget to put a good silicone case on your headphones when listening to music. This can add balance to your headphones and give you better bass performance. Specifications: 1. Name: Silicone Memory Foam In-Ear Earphones 2. Specifications: 4.2mm 3.
