Peak In-ear Performance
Being able to hear yourself clearly is key when it comes to performing your best. The Sennheiser EW IEM G4 provides this with the luxury of being a wireless in-ear system. No matter where you go on stage or even in the crowd, you can still hear yourself without any trailing wires and less stage volume. Another perk of in-ears is you won’t get any feedback.
Included with the Sennheiser EW IEM G4 is a high end rackmountable transmitter, with 1,680 tunable UHF frequencies, a rugged bodypack receiver and a comfortable pair of IE 4 earphones. With increased bandwidth and power than its predecessors and a transmission range of up to 330 feet and compatible with previous evolution systems, this really is everything you could ask for in a wireless system.

ACS - 'Evoke Live Pro'
Custom In-Ear Monitor Headphones

Impressive Sound Quality ACS have re-engineered their single driver In-Ear Monitor to take advantage of the latest technology available. The ACS Evoke Live! features the same field proven detachable cable system as the other Live! products, low profile full concha custom fit soft silicone ear moulds and the latest Hybrid transducer technology from Knowles Electronics.
Amazing Features
• 2 Knowles Wideband Balanced Armature Drivers
• Patent pending IRIS and exclusive SSI technology

• Cable Length 1.3m
Following Modern Technology

Greater Low Frequency OutputACS have worked alongside Knowles Electronics to introduce their new Hybrid transducer technology to our ACS Evoke Live! product. Knowles Electronics have combined elements of their existing balanced armature transducers with those of a more traditional dynamic loudspeaker.
One of the issues with such small individual transducers is a lack of low end in the frequency response. To work around this issue Knowles have added the ability to vent the transducer to give greater output in the lower frequency range.
All of these improvements and the addition of the Live! functionality combines to give you a dynamic high-quality IEM which can be paired with the Ambient Live Pack. Many who have listened to them do not believe such a broad and detailed sound is possible from a single driver IEM.
