So, whether you’re hosting in a warehouse, field, or living room, crystal-clear audio surrounds you, ensuring every listener experiences the same rich detail.
Customisable Party Sound Modes
Featuring a dynamic sound character control knob, this Bluetooth speaker allows you to shift between pre-party, peak, and after-party modes. Thus, you can tailor the sound from relaxed to high-energy, perfect for chill background tunes or dance-floor intensity.
Extended 40+ Hour Playtime
Offering over 40 hours of portable performance, this party speaker keeps the music alive well beyond the night. Moreover, when the battery runs low, you can swap it for a backup or plug in via AC cable, ensuring non-stop music from first track to final encore.
Controlled Bass Performance
Designed with a closed-box build, this party speaker ensures tight, natural-sounding bass with exceptional depth. With rear-firing drivers and a connected tweeter cone that amplifies clarity and range, every beat and vocal stays distinct even in larger spaces.
Durable and Splash-Resistant Design
Built with an IP54 rating and integrated drainage system, this party speaker easily handles rain, dust, and outdoor conditions. So, you can move the party from indoors to outdoors without missing a beat or worrying about the weather.
Integrated Stage Lighting
