Sennheiser reinvents the dynamic transducer with its new in-ear monitoring headphones

IE professional models 400 Pro and IE 500 Pro offer natural sound reproduction with high resolution, Secure and comfortable fit with break-proof cable connection, Patent pending.

Sennheiser has presented, during the recent celebration of NAMM 2019 in California (Us.) Two new models of its range of professional in-ear headphones: Ie 400 Pro and IE 500 pro, Specially developed for sound engineers, musicians and DJs, to strict specifications on a new production line at the company's German factory.

"Monitoring is essential in the preparation of a concert," explains Jannik Schentek., Sennheiser Product Manager-. In addition to being in contact with the rest of the musicians, In-ear headphones allow the artist to hear himself, helping you improve your performance. The IE series has been designed with this goal in mind.".

Available on the market from March 2019, the new IE in-ear headphones 400 Pro and IE 500 Pro deliver accurate, natural sound for monitoring. "We have reinvented the principle of the single dynamic transducer.. Other in-ear headphones within the same price range work on the principle of balanced armor, which in our opinion is inferior to the dynamic broadband transducer.", underlines Schentek.

In the case of balanced armor headsets, a technology used in hearing aids, whose size should be as compact as possible, "They need several transducers to reproduce the frequency range., which can cause crossing effects and phase differences between transducers, says this manager- . IE models 400 Pro and IE 500 Pro use a single high-performance dynamic transducer that easily covers the entire frequency range, resulting in accurate and distortion-free audio reproduction".

This single-transducer technology, named TrueResponse, Delivers all-natural sound, Clear and spacious, with total harmonic distortion (Thd) less than 0,08% at 1kHz and 94dB.

This very precise sound that is offered reduces acoustic stress for the user, that you can adjust your monitoring headphones to a much lower volume.

Sound retains full power, Even in the noisiest environments. In this way, Musicians can monitor their sound and concentrate entirely on their performance. This is pointed out by singer and songwriter Fin Greenall, after using the IE headset 500 pro: "It's like I'm not wearing them.. The more I used them, But I was appreciating how good they are. The media is really clean, Amazing bass and treble aren't too harsh, In short, they are balanced and just what I need".

As the transducer has a diameter of only 7mm, IE headphones 400 Pro and IE 500 Pro feature a comfortable ergonomic ear mold, Discreet and extremely light. In addition, Supplied with various silicone pads of different sizes, as well as a special memory foam, que se expande para lograr un acople perfecto al canal auditivo.

El denominado ‘túnel de sonido’ de los auriculares tiene dos posiciones de descanso donde fijar las almohadillas, acomodándose así a las distintas longitudes del canal auditivo. El resultado es un acople seguro y cómodo, muy similar al de los moldes auriculares fabricados a medida.

In addition, este sellado proporciona una potente reproducción de los graves y una reducción del sonido ambiente de hasta 26dB, protegiendo así al usuario contra los ruidos excesivos en el escenario.

Al igual que todos los modelos in-ear de esta serie profesional, los modelos IE 400 Pro and IE 500 Pro están provistos de un conducto de cable interno a prueba de roturas (patent pending), cuya funda antitorsión se asienta directamente en el molde auricular, lo que garantiza su longevidad frente a los rigores de uso en el escenario.

Estos nuevos modelos de Sennheiser (brand that markets magnetron in Spain) se suministran con un cable desmontable, con gancho reforzado para la oreja. En el caso de IE 400 pro, el cable es negro y de conductores paralelos, mientras que en IE 500 Pro es transparente y de par trenzado, con un mayor rechazo al ruido estructural.

As far as sound is concerned, la diferencia entre ambos modelos “está en los medios -aclara Schentek-. between 1 and 2,5 khz, IE headphones 500 Pro tienen más presencia y ofrecen un sonido más directo, amplio y profundo, lo que ayuda a los artistas a situarse en la mezcla. In addition, tienen una respuesta en frecuencia más amplia y algunos dB más de presión sonora, lo que puede resultar crucial en escenarios ruidosos”.
