The JBL Tune 310C USB-C in White are wired in-ear headphones that bring JBL Pure Bass Sound and Hi-Res Audio certification to any USB-C device — connecting directly to USB-C smartphones, laptops, PCs, MacBooks, tablets and gaming devices without a dongle, adapter or Bluetooth, delivering 9mm dynamic driver performance across a 20Hz–40kHz frequency range that qualifies for Hi-Res Audio certification and never requires charging. The 9mm dynamic driver delivers JBL's signature Pure Bass Sound — the deep, powerful, forward bass reproduction that JBL has engineered into professional and consumer audio products for over 75 years, calibrated to punch through without muddying the mids or masking the detail in the treble that makes vocals, strings and high-frequency instruments sound clear and distinct alongside a heavy bass track. The 20Hz–40kHz frequency response extends significantly beyond the 20kHz upper limit of standard headphone specifications — reaching into the ultrasonic range that Hi-Res Audio certification requires, capturing the harmonics and overtones of recorded music that ordinary headphones with a 20kHz ceiling simply cannot reproduce, and producing the improved spatial clarity, instrument separation and overall sense of recorded-space dimensionality that Hi-Res Audio playback delivers to listeners whose source files include the extended frequency content.

The 3-button remote on the flat cable handles everyday listening and call management without touching the connected device — the centre button plays and pauses music and answers and ends calls, the volume up and volume down buttons adjust playback level directly and the EQ preset cycling function switches between Default, Bass and Vocal sound profiles with a single button combination on the inline remote. The three EQ presets address the most common listening scenario preferences without requiring an app — Default provides the JBL-calibrated neutral-warm baseline tuning, Bass emphasises the low-frequency response for hip-hop, electronic, R&B and bass-forward genres, and Vocal boosts the mid-range presence for podcasts, audiobooks, call audio and any content where voice intelligibility and warmth are the priority. The built-in microphone captures voice for calls with the sensitivity and positioning appropriate for the inline remote's location on the cable, keeping calls clear and the hands free without removing or repositioning the earphones. The flat cable design prevents the tangling and knotting that round cables develop when coiled in a pocket or bag — meaning the JBL Tune 310C can be stored loosely, pulled out and used immediately without the unwinding delay that tangled round cables cause. At 14.3 grams total weight, the Tune 310C is genuinely ultraportable — light enough to carry as a permanent everyday pocket or bag accessory alongside a laptop, phone or tablet for ready use in any situation where audio quality from a USB-C device is needed. ⚠️ USB-C compatibility varies by device — check your device's USB-C audio support before use.
