Product Philosophy

From early 2007 ESI started using the slogan Clever. Better. Innovative. Professional. - we feel that these four words describe our product philosophy in the simplest way possible, a few product examples and comments from reviews illustrate that:

Today ESI is one of the most well known brands for home recording equipment. This is only possible, because all our products have been developed with the requirements of serious musicians in mind.

The MaXiO XD recording system for PC & Mac with PCI or PCIe interface, is our top-of-the-line solution for serious professional recording applications. Martin Walker from Sound On Sound (UK) concluded in his review of the PCI version: "With excellent audio quality and a huge number of versatile features, ESI have managed to cram a huge amount into their MaXiO XD system."

ESI has became famous over the years for a number of very innovative product designs and special product features - just think of technology like DirectWIRE as part of our well-known EWDM driver that became a standard in many computer based home studios around the globe.

SampleRobot, the automation sampling software from SKYLIFE, won the Innovation Award 2006 of KEYS (Germany), voted by readers. The family of SKYLIFE products is growing with SampleRobot Version 2, SampleRobot Essentials and the forthcoming WaveRobot. Scot Solida from Computer Music (UK) wrote about SampleRobot: "SampleRobot is like the second engineer you always wished you had." - well, that's really innovation!

ESI offers products that are among the best in their class.

nEar05 eXperience was the first active studio monitor in its price range that used a kevlar low frequency driver. Other vendors have since copied our idea, but reviewers like Paul White in Sound On Sound (UK) reach an important conclusion: "With a speaker this size, you don't expect a lot of low end, but the nEar05 does better than expected on this score. / ... they exhibit better bass extension than most speakers of this size."

ESI products are frequently recognized for their unique and clever design.

A very good example is our Juli@ audio interface with its special and totally unique swappable I/O section. Martin Walker from Sound On Sound (UK) concluded: "With a clever hardware design, good audio quality, and well-written and versatile drivers, ESI's Juli@ should find plenty of admirers."


A number of ESI products are based on key technologies like EWDM or DirectWIRE that have been developed and improved by ESI engineers with years of experience.
