JBL C100SI Complete Review

Build Quality and Design

C100SI is an in-ear type earphone with a metallic finish and stylish design. The angular shape of the buds deliver an additional hold and do 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 weighing just 11 grams for the earpiece and 50 grams for the earphone including cable.

The earphone is made mainly with plastic and 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 help 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.


  • Crystal clear audio
  • Highly recommended for bass lovers
  • Lightweight and ergonomic design
  • Budget-friendly
  • Noise isolating mic
  • Fantastic passive noise cancellation
  • Supports voice assist features


  • Not braided cable
  • No volume control
  • Not waterproof/ sweatproof

Final Comments

Here we have provided a complete review from our own experience and specification description. We hope this article helps you know everything about it.

This includes JBL C100Si specs and user review. If you are a regular user comment below your reviews.

  1. Is JBL C100SI good/ How is JBL C100SI?

    Yes, obviously. If you are looking for an earphone with premium quality and decent build quality this is one of the best you can get under this price range.
    The 9 mm driver delivers you deep bass and crystal clear audio. 
    But on the other hand, it lacks some other features like water resistance and a volume control button. So it is not a good option to wear in a moist and sweaty environment.

  2. Are JBLC100SI sweatproof and waterproof?

    No, it is not sweatproof and waterproof. It is the main downside of this item. 
    So can't use it in the gym.
