The high expectations placed on in-ear monitoring are effortlessly satisfied by the IE 40 PRO thanks to an advanced dynamic driver system. The innovative diaphragm delivers a warm sound, yet powerful and precise, even in extremely loud environments. Even at maximum sound pressure levels, the signal remains distortion-free and precisely defined. The IE 40 PRO is a superior monitoring device for musicians and DJs that adapts to every ear. A compact design combines a secure fit with excellent wearing comfort. It’s robust construction is designed to be suitable for the rigors of stage use from the connection to the cable duct.
The IE 40 PRO improves the way you perform by enhancing the way you hear.
Innovative, dynamic 10mm broadband transducer for powerful, precise monitoring
Dynamic driver system reduces acoustic stress factors through homogenous, distortion-free reproduction
Secure fit and high level of wearing comfort; Innovative single driver design enables a slim and ergonomic construction
Excellent shielding thanks to optimized earpiece and flexible silicone and foam tips
Cable with innovative internal cable duct (patent pending), fit for stage use
Dynamic drivers of the next generation
Whereas most IEM systems use multi-driver solutions derived from hearing aids, the IE 40 PRO uses a next-generation dynamic single-driver. As it turns out, the frequency range does not have to be split up into sections but remains harmonious as a whole. It sounds “well-rounded”, and its frequency spectrum has been considerably expanded. There are no distortions because the special diaphragm – unlike the more rigid drive principle of the multi-way drivers – resonates easily even at maximum sound levels. Phase problems and dissonances in the inner ear are therefore also precluded. The difference is audible, even noticeable in the entry-level model.
Small but mighty. Comfortable.
A big sound, but small enough to fit your ear: the advanced driver system brings a considerably expanded sound spectrum to the ears of musicians, sound engineers and DJs. The design, on the other hand, has been optimized, checked against hundreds of ear shapes, and redesigned. The result is flat, sits securely and does not ‘carry any weight,’ even during lengthy sessions.
Reinvented down to the last detail
Without monitoring sound, there is no performance. The IE 40 PRO is designed to provide the necessary reliability. To this end we have even reinvented stage-compatible cabling – the internal cable duct is a unique feature (patent pending). In short: the new system meets high expectations and withstands high stresses.
As a gigging and studio session guitarist I have had a lot of experiences with in ears and headphones. What seems to be the most important thing for me at a young age is QUALITY IN THE AFFORDABLE. Being the entry level model for the IE series, the IE 40 Pro surpasses what most entry level in ears attempt to do. They are super comfortable, have great sonic representation of low, mids, and highs, and stay snug inside the ear unless intentionally removed (and I move a lot on stage). I have been used to the Shure 215s for so long, and have had consistent problems. When I first tried out the IE 40 Pros it was like a filter was removed. Everything was so clear, and certain instruments that were panned truly felt like they had their own place in the mix. During one particular gig in NYC, an artist I was playing with forgot her in ears. I let her borrow the IE 40 Pro during soundcheck and she wanted a pair of her own immediately. I have even used them to record and mix music myself. These things can do it all, and it gives me a great reference point to wonder what the IE 400 and 500 models would sound like!
**Be prepared to be blown-away. I have started to run the IE40 Pro in for a friend. They are a gift, I owe this person a favour, so I can't keep them. I have a really expensive Hi-Res music player, and non-Sennheiser expensive multi BA in-ears, and for under £100 I'm amazed how impressive these sounds playing my FLAC files, all differing genres.
I have smaller ears than most people and I cannot wear most in ears. I am SO HAPPY that Sennheiser has made a pair of in ears that fit me and sound amazing. They are so comfortable I can even sleep with them in. This is the second pair of Sennheisers I own and I'm hooked for life.
