The JBL C100Si Wired Earphones – Black brings JBL’s professional audio heritage to a compact, everyday wired in-ear earphone. JBL Pure Bass is the acoustic tuning that JBL applies across its full product range — from concert hall line arrays to portable earphones — prioritising natural, full-range bass reproduction through driver engineering rather than electronic colouration. The C100SI delivers a 20Hz–20kHz frequency response at 100dBSPL sensitivity, which is sufficient for high volume from any smartphone, tablet or portable device without amplification. The angled earbud housing is a deliberate ergonomic choice: rather than a straight cylindrical housing that sits perpendicular to the ear canal, the angled design follows the natural angle at which the ear canal enters the outer ear. This alignment reduces the leverage that the weight of the earbud and cable exerts on the canal walls, making the C100SI more comfortable to wear over extended periods. The premium metallic finish gives the earphones a quality appearance above their price point. Three silicone eartip sizes — small, medium and large — are included for an individualised canal fit. The single-button remote handles playback and calls, and the noise isolation microphone is designed to attenuate ambient noise before it reaches the microphone capsule. Genuine JBL by Harman. 1-year warranty.
JBL Pure Bass
Harman Audio Heritage — Deep, Natural Bass
JBL is part of Harman International, the professional audio company whose equipment is used in the majority of the world’s concert venues, cinemas and recording studios. JBL Pure Bass is the consumer expression of this professional bass tuning philosophy: rather than adding bass through an equaliser boost — which increases distortion and compresses dynamic range — the driver is engineered to physically reproduce low frequencies with the cone geometry, voice coil design and enclosure tuning needed for natural bass output. The result is bass that sounds full and impactful rather than artificially boosted — present without masking the midrange and treble detail. At 100dBSPL sensitivity and 20Hz–20kHz frequency response, the C100SI covers the full range of audible frequencies at volumes appropriate for everyday use from any standard headphone output.
Angled Buds Design
Ergonomic Housing — Extended Comfort Fit
The angled earbud housing is designed to align with the natural axis of the ear canal rather than inserting perpendicular to it. The human ear canal does not run straight inward — it angles slightly forward and downward from the outer ear. A straight cylindrical earbud housing sits at an angle to this axis, creating uneven pressure against the canal walls and causing the earbud to gradually work loose during movement. The angled housing follows the canal’s natural axis, which distributes pressure evenly around the circumference of the tip, creating a more stable seal and a more comfortable fit for extended wear. This is particularly noticeable during exercise or commuting, where head movement would cause a straight-housing earbud to shift but the angled design remains in position. Three eartip sizes allow adjustment for different canal diameters.
Metallic Finish · Remote + Mic
Premium Appearance — Call Ready
The premium metallic finish on the C100SI housing distinguishes it from the fully plastic construction typical of earphones at this price — the metal surface catches light differently and contributes to the earbud’s stability in the ear by adding a small amount of controlled weight. The single-button inline remote provides core controls: press once to play or pause and to answer or end calls. The noise isolation microphone uses the in-ear seal created by the eartips to physically block ambient sound from reaching the microphone capsule — reducing background noise on calls without active processing. The 3.5mm straight connector works with any headphone-equipped device: Android phones, iPhones (with adapter on models without a jack), MacBook, Windows laptops, tablets and audio players.
Great choice if you…
✔ Want JBL Pure Bass sound in a lightweight everyday earphone
✔ Prefer angled earbud housing for a more secure, comfortable canal fit
✔ Need reliable wired earphones for commuting, gym or daily use
✔ Want a premium metallic finish above the typical budget earphone look
✔ Use any device with a 3.5mm headphone jack
Consider something else if…
✖ Your phone has no 3.5mm jack — a USB-C or Lightning adapter will be needed
✖ You need volume up/down buttons — single-button remote only
✖ You need a tangle-free flat cable — the C100SI uses a round cable
