Ultimate Ears and 18+ Ambient at a glance

From the quietest moments of your set to the most epic crescendos, the Ultimate Ears and 18+ Pro Ambient deliver consistent, world-class sound at any volume. A four-way crossover and six proprietary drivers provide more headroom at all frequencies and bring out the dynamics of your performance.

The four-way crossover provides more detail across the frequency spectrum. Two woofers and tweeters provide additional headroom for a wider dynamic range. Excellent acoustic isolation suppresses noise in any environment Customized, individual fit ensures safety and comfort. The waterproof connection system and SuperBAX cable ensure lasting durability

The "Ambient version" offers the possibility to adjust the attenuation level in two stages. The filter with a very practical attenuation of 12 dB attenuation is permanently installed, the 26 dB maximum attenuation is achieved by simply closing the Ambience hole with a plug. This allows you to react to the respective stage situation. Highly recommended for front people, quieter music, TV musicians and anyone who can't cope with this feeling of isolation.
