Exposure to high-volume stage monitoring can damage the delicate structures of your inner ear, leading to noise-induced hearing loss (NIHL) and tinnitus. For musicians and engineers, the louder the stage environment, the quicker this damage can occur.


Cosmic Ears custom moulded in ear monitors are expertly designed to prevent these issues, providing a massive 26dB of ambient noise reduction. This allows you to hear your monitor mix with crystal clarity at much safer volume levels, reducing ear fatigue and protecting your long-term hearing health.


Each pair is precision-crafted from clinical-grade materials for maximum comfort and a secure fit that won't move while you perform.


Using proprietary ModTec drivers and SAMS (Solid Acoustic Mass Shell) technology, they deliver a high-fidelity audio experience tailored specifically to your role on stage. 


  • ✅ Superior isolation reduces stage noise by up to 26dB.
  • ✅ Perfect custom fit ensures they stay secure during active performances.
  • ✅ Professional driver setups tailored for vocalists, drummers, and engineers.
  • ✅ Reduces listening fatigue and protects against permanent tinnitus.
  • ✅ 3D printed shells for ultimate precision and digital record-keeping.
  • ✅ Handmade in the UK with high-quality, replaceable cables. 


Who Benefits Most?


  • Vocalists & Guitarists (C6A): Incredible mid-range detail for perfect pitch and clarity.


  • Drummers & Bassists (C8A): High headroom and sub-bass response needed for rhythm sections.


  • Sound Engineers (C6R): A flat, transparent frequency response for accurate mixing.


  • Keyboardists (C4A or C8A): the C4A for bright, detailed piano definition, or the C8A for powerful sub-bass for synth and organ patches


  • General Musicians & Hobbyists (C3A): A versatile, high-fidelity all-rounder that delivers a balanced punch across all genres
