The first impression after looking through Sharp’s Gx-BT480 Bluetooth speakers was – copy of JBL. When we took the GX-BT480 out of its packaging, it turned out to be quite similar to JBL’s Xtreme speaker. Slightly stouter, but more, cylindrical in shape, with simple controls at the top, including handles for attaching a convenient strap, just like the Xtreme. 

The biggest difference is in the backs, where JBL passive basses are used, while the Sharp has inputs (power supply, 3.5 mm audio and micro SD slot) on one side, all sealed by a rubber cover. On the other side there are power switches, an equalizer, an input selector and back and forth controls.

Aside from basic Bluetooth connectivity and an additional cable, the GX-BT480 can play music from a micro SD card, which is sometimes useful as you don’t need to rely on your mobile phone, especially in situations where the music gets interrupted during a call. It can read micro SD cards up to 32GB and recognize MP3, FLAC, WAV and APE tracks.

One of the side panels is the equalizer, which allows us to adjust the speaker’s audio properties.

The GX-BT480 is equipped with a 10,900 mAh battery that provides up to 20 hours of back-up with a charging time of 3.5 hours. The charger is designed with a micro – USB – connector (3A / 5V) and can be recharged with an emergency outlet or power bank.

The sound quality is satisfactory, especially at low and medium volume. If you play louder, the bass is much more blurred and weaker than the competitor JBL Xtreme. If you keep the volume down to 50%, the difference is minimal, and we really liked the bass tuning functions with the equalizer button. There are three modes: Standard, Movie (increased midrange, softer bass) and Bass Boost for parties and open space.

We should also mention that the GX-BT480 is much more economical than the Xtreme. So it’s worth considering if you’re not bothered by the lack of chaining (pairing two or more speakers) and looking for playability without connecting your cell phone.
