Re-establishing Volume Levels/Balance between Earbuds

As with all in-ear headphones, our range of TWS headphones can be susceptible to a build up of dust and earwax. This can cause low volume on one or both earbuds, or balance issues (e.g. right earbud is louder than the left earbud). To reduce the likelihood of these issues occurring, it is a good idea to periodically clean your earbuds and your ears. Clean the earbuds by removing dust and wax after each use, using a pointed toothpick to remove larger amounts and a small amount of rubbing alcohol applied to a cotton swab for final degreasing.

If you are experiencing volume or balance issues, always check for wax and dirt in and around the earbud and driver and complete cleaning of the earbuds as described above. If the issue persists, there may be earwax/dirt stuck in the small holes in the grille in front of the driver, preventing sound output. To resolve the issue try dipping the affected earbud tip into a solution of lukewarm tap water and a small amount of dish soap (washing up liquid). The earbud tip should only be put into the liquid up to a maximum depth of 1-2 mm only (see images below). Immersing the earbuds in water or putting the earbuds in water at a larger depth than this could void your warranty. Keep the earbud tip in the water for about 2-3 minutes, then wipe/clean the grille with a small brush (such as a toothbrush). The should remove the wax and resolve the volume/balance issues.

Wi-Fi vs. Bluetooth streaming

Using Wi-Fi allows you to listen to your music in a higher sound quality since Bluetooth protocol compresses the audio signal, where Wi-Fi data easily stream HD Audio content. Take calls without interrupting your current audio music, where Bluetooth will interrupt the stream, because it is a one-way protocol. Control your music from anywhere in the house, where Bluetooth have a limited range. Play the same music across multiple speakers and when using the newest connect features, such as Spotify Connect or Chromecast built-in, then you don't have to worry about battery life, since the devices playing is doing all the data transmission compared to Bluetooth, where it is data between source and device.

Why do I need to use the calibration microphone included with my JBL Quantum ONE?

We believe the baseline performance of the QuantumSPHERE technology is cutting edge in terms of localization. The calibration feature improves upon this performance by calibrating the system to your individual anatomy.

Why are my headphones shown as “speakers” on Windows?

The “Speaker” mode allows the JBL QuantumENGINE to receive more than two channels of audio. It also prevents some applications from adding extra signal processing intended for other headphones, which would negatively impact the performance of the JBL QuantumSURROUND or JBL QuantumSPHERE 360 technology.
