‘Acoustic’, ‘Amplified’ and ‘Fcking Loud’ are part of the Crescendo Pro Music range ear plugs. The Pro Music ear plugs provide state of the linear sound transfer. The integrated acoustic filters contain the same technology as used by professional musicians in custom earmoulds and In Ear Monitors.

The Pro Music ear plugs provide a tuned, flat attenuation response, so all frequencies are reduced by almost the same level and you will lose nothing of the original sound, it’s just brought down to a safe level. Crescendo Pro Music ear plugs are the best high fidelity universal ear plugs on the market.
