Variphone (Westone)
Elite Series ES2
Custom Fit In-Ear Monitors

Now these are the best In-Ear monitors around. Extremely comfortabel to wear and the soundquality is sublime! I've never heared such quality before.

I use them in two different configurations.

• I use both the earpieces on electric gigs, providing me with the full monitor mix. This is when they protect my ears for long term damage by high stage volumes.
• Or I only use one of them during "acoustic" gigs. As fill-in for my more-of-me-mix. Allowing me to communicate on stage and with the public.

Professional 'dual driver' in-ear monitor

Custom made to provide a precise, comfortable fit, the dual driver ES2 provides exceptional low frequency response, smooth mids and articulate highs. Our most popular and versatile custom monitor, the ES2 is designed for the most discriminating artists. The ES-2 is designed according to the highest professional standards.  For sound production it is without doubt the most accurate personal monitor available on the market.  Every earpiece contains 2 drivers.  One for the bass tones and the second for the high tones, together with a passive crossover.  The principle of 2 drivers leads to an exceptional frequency response.  The average attenuation of these monitors is 26dB.  Indisputably 'world class' in-ear monitors.
