Complete JBL C100SI Review
In the above section, we have provided the full specification without missing anything. Now have a look at our findings after our use.
Build Quality and Design
C100SI is an in-ear type earphone with a metallic finish and stylish design. The angular shape of the buds delivers an additional hold and does not fall off frequently.
The earbuds are lightweight, compact, and fit snugly. So you can wear it for long hours comfortably.
The 1.2 m rubber cable is of average quality and not braided. They really light and weigh just 11 grams for the earpiece and 50 grams for the earphone including cable.
The earphone is made mainly with plastic and the build quality is average. So always try to keep your earphones safely without much
Sound Quality and Performance
The JBL C100SI is powered by powerful 9 mm drivers that deliver high-quality audio with deep bass. It supports both Siri and Google assist.
On the downside, it is not waterproof or sweatproof. So we don’t recommend this for workouts.
The noise cancellation is excellent (passive). So you can listen to your favourite music or movies in a crowded area comfortably at a lower volume.
The lows and highs are very good.
Premium Features
The integrated noise isolating mic helps you a lot in making calls in a noisy area.
It has one Multi-Function Button (MFB) to manage calls and also to select a next/ previous song. But unfortunately, it doesn’t have any volume control.
