The JBL C100SI is a tiny, very comfortable earphone with punchy bass and bright detail, but it leaks sound at higher volumes and its mids are slightly warm.

Third-party reviews

Based on ratings from across the web.
Reviews last updated: November 2026 · How we calculate this

What customers like about JBL C100si

  • High-quality sound with crisp vocals and clear highs for the price point
  • Punchy and energetic bass typical of the JBL signature
  • Lightweight and ergonomic design with angled buds for a comfortable and secure fit
  • Excellent call quality via the integrated in-line microphone
  • Effective passive noise isolation due to a tight acoustic seal
  • Great overall value for money in the budget segment

What customers don't like about JBL C100si

  • The rubber cable is prone to tangling and may feel less durable than braided options
  • Lack of onboard volume controls on the single-button remote
  • Sound can become slightly 'mixed up' or lose separation when listening to complex genres like metal
  • Treble-heavy profile may require equalizer adjustments for those preferring deeper bass
  • Basic plastic housing can feel average or 'cheap' compared to higher-end models

Verdict

The JBL C100SI is a dynamic, ultra-lightweight in-ear headphone featuring 9mm drivers that deliver JBL's signature sound with a frequency response of 20Hz – 20kHz, 16-ohm impedance, and 100dB sensitivity. These wired earphones include a gold-plated 3.5mm jack, a 1.2-meter cable, and a one-button universal remote with an integrated noise-cancelling microphone for managing calls on Android and iOS devices. Main pros include its punchy bass, feather-light comfort with three sizes of angled ear tips, and high price-to-performance value for music clarity. However, notable cons include an average rubber cable that is prone to tangling and may feel less durable for heavy active use, as well as a lack of dedicated volume controls on the remote.
