🎺 BelloFlex Cup Mute™ – The Adaptive TPU Trumpet Cup Mute
Shape your sound like never before.
The BelloFlex™ is a revolutionary flexible cup mute made from durable TPU, designed to give trumpet players precise tonal control with a simple push. Whether you want a tight, focused studio sound or a more open, velvety timbre, the FlexiCup™ responds instantly to your playing style — and your hand.
 
🌟 Features:
Adjustable Tone Control
Vary the depth of insertion to dial in your desired sound — from bold and brassy to soft and smoky. Push in for a darker, more focused tone; pull out for more resonance and openness.
Ultra-Lightweight Design
Constructed from flexible TPU, the FlexiCup™ is significantly lighter than traditional cup mutes, reducing bell strain and improving balance while playing.
MuteClip™ Compatible
Snaps seamlessly into your MuteClip for fast swaps during gigs, rehearsals, or recording sessions.
Durable & Resilient
TPU material resists cracks, dents, and warping — perfect for travel, stage work, and everyday practice.
Silent Impact
Unlike rigid metal or fiber mutes, the FlexiCup™ won’t clatter when dropped or bumped — ideal for pit orchestras or quiet stage transitions.
