About our R1 Series

About our R1 Series

We asked ourselves "How can we improve the universal IEM and get close to a custom IEM fit?" and started to rethink & re-design the 'universal' style. We partnered with Freebit® from Norway with their ear-interface design, which is a well proven interface used in sports earphones for a secure fit with the stability we wanted but we had the main cable connection in the way, where regular "universal" IEMs have their cable connectors placed on the top section of the IEM body & the front casing of the IEM is reserved to display the brand.

Okay, we understand the presentation of the brand is important; we understand marketing as well. We did not want a compromise and insisted to achieve a fit as close to a custom IEM as possible. Let's figure out where we can put our brand later… With the Freebit® interface, we relocated the cable connector to the front casing (yes, where everyone else puts their brand). This required a completely new design approach to the internal structure as well as the acoustics engineering. Fortunately, we have a great team of acoustic engineers & music industry professionals with the commitment to make bold changes & get the acoustics right.

We achieved our goal of getting a secure, stable & comfortable fit with the cable being an additional anchor point above the ear and the tether slider on the back of the neck. The IEMs stayed in place, felt comfortable & had the neutral sound signature we wanted.

Not only that, we measured up to 22dB attenuation by getting a proper fit with the Freebit® ear-interface pieces together with the in-ear silicone gels & the Comply™ tips.

Our new approach to IEM design is now protected by patents in the U.S.& other countries.

It took us longer than we expected but we believe we have an alternative to spending a small fortune on custom IEMs. After all, we're musicians & music lovers as well.

Back to a place for putting our brand; we didn’t have any room to print brand on the final product but we did manage to add our logo from the inside of the casing for a stealth look.

We created a well thought out product which gives the best possible user experience, acoustics to match &fits like a custom IEM.
