"It's been a long time since I've been really excited about a headset. With the introduction of the new Sennheiser S-1 and its adaptive, four-microphone sampling technology, Sennheiser sets a new headset standard."
- Marc Lee, Plane & Pilot Magazine.

The Sennheiser S1 Digital aviation headset, designed in tandem with BMW DesignWorks USA, gives you maximum control over noise levels in the cockpit, so you can focus on the joy of flying. At the push of a button, the S1’s exclusive NoiseGard™ / digital technology accurately analyzes the cockpit’s current noise levels to achieve superior noise cancellation during all phases of flight—from take-off to cruise to landing. Design features like adjustable headband contact pressure and a special “comfort zone” for glasses ensure you stay comfortable. And with a Bluetooth interface, clear voice transmission and a customizable treble boost function, you’ll never miss a word.

Sennheiser S1 Headset Highlights:

  • Exclusive Smart Adapt Technology customizes noise reduction to your aircraft environment and current phase of flight. The digital adaptive circuit offers noise cancellation second to none.
  • Customized comfort. Since not all heads are created alike, the S1 offers three different headband tension settings to give you the right fit.
  • Superior audio clarity with customizable treble boost.
  • Keep your ears safe with Peak-Level Protection to ensure that any sound greater than 110db is automatically muted to an acceptable level.
  • Soft, light, comfortable ear seals. Specially designed ear pad "comfort zones" perfectly accommodate eyeglasses.
  • Bluetooth wireless connection to your cell phone and music player.
  • Legendary Sennheiser Audio Quality. Sennheiser knows how to make your tunes sound like they should.

Sennheiser S1 Digital NoiseGard ANR

At the push of a button, the S1’s exclusive NoiseGard digital technology accurately analyzes the cockpit’s current noise levels to achieve superior noise cancellation during all phases of flight—from take-off to cruise to landing. The graphic below shows the real world frequency response of the cockpit noise in a single engine prop. The top line shows the cockpit noise without any headset. The second line is the cockpit noise heard using a standard passive headset. The third line shows the noise cancellation using a top of the line standard ANR headset, and the bottom line is the noise with the adaptive, digital, NoiseGard found in the Sennheiser S1 Headset.

Bluetooth Wireless and Audio Functions

Sennheiser S1 BluetoothThe Sennheiser S1 Headset has integrated Bluetooth wireless capabilities to allow you to connect the headset to any Bluetooth equipped mobile phone or portable music player. The control box on the S1 Headset gives you remote access to all features of the mobile device if it supports the Bluetooth profile. With the S1 control box you can skip songs, pause, mute, increase or decrease the sound and more. The S1 Headset can also be used as a wireless headset for your mobile phone outside of the aircraft, for example to file a flight plan while standing on the tarmac.

The Sennheiser S1 Headset has two separate audio mixers; one for music and the other for mobile phone and ATC communications to ensure that both speech and your music sounds great! Music streaming via Bluetooth 2.1 is done via the A2DP and AVRCP profiles.

Each S1 Headset can quickly and easily be configured for Audio Muting at any time. When Audio Muting is turned on, the audio signal from your music or mobile device is automatically decreased by 24 db during any ATC communication so you don't miss any important instructions.

Adjustable contact pressure

Sennheiser understands that not all heads are created equal. What may fit one person may be much too loose or tight on another person. Therefore, they have introduced adjustable contact pressure to provide the maximum comfort and best fit for virtually everyone! Each side of the S1 Headset offers three contact pressure adjustments - minimum, medium and high contact pressure.

Soft Ear Seals and Sunglass Comfort Zones

Sennheiser S1 Comfort ZonesAnyone that has worn eyeglasses or sunglasses during flight knows that after a while you start to have discomfort where the ear cup presses on the temple of the glasses against your head. Sennheiser solved this problem with a special material on the ear cushions of the S1 Headset. On the areas where the glasses normally press against the temple, Sennheiser has added a soft, perforated memory foam that is used to avoid uncomfortable contact pressure. And, because it is a special memory foam you are ensured the best possible seal when used with or without glasses. The result is a light and comfortable feeling with a great seal to block external noise.

Improved Passive Noise Attenuation

Effective passive noise attenuation strongly depends on a proper sealing of the ear pads against the head. Everyone's head is a different size and shape and some pilots suffer from a good sealing of the ear cups, especially in the lower area of the ear cup. The S1 has solved this problem with a V shape on the lower part of the ear cups which allows for better sealing against the head, especially for people with a smaller face. Sennheiser also designed the S1 Digital Headset to have a lower pivot point of the ear cup than most headsets. With the lower pivot point of the ear cup, you will get better contact below the ear where the jawbone is located and substantially enhance the overall passive noise attenuation.

"The S-1 blew me away. It was the first ANR headset that worked well in my noisy open cockpit... This was easily the most comfortable headset I've worn... Sound-wise, the S-1 was pure Sennheiser - crisp, clear and full-bodied; the antithesis of tinny. The ANR worked famously, and playing with the push-bottom sound sampling and resulting tailored noise attenuation throughout the flight was nothing short of impressive. It was like I had created a custom headset for my environment only."
- Marc Lee, Plane & Pilot Magazine.

Customer Reviews For Sennheiser S1 Digital ANR Headset:

Sunday, July 13, 2014
by Dale from Millington, TN 
Review: Comfortable headset, especially for long duration flights. Noise cancellation better than Bose, Lightspeed, or David Clark. Only negatives are that the bluetooth is problematic at best to get to connect to my HTC android phone and the muting fade-in is extremely slow to come back after an ATC call. Battery life seems to be good.
Overall, a good headset with a couple of small issues. Fidelity is the usual that I would expect from Sennheiser as I have used their products in the broadcast environment for years.

by Robert from Mitchellville MD USA 
Pros: Passive noise reduction is better than Bose. 3 level adjustable tension for better comfort. Adaptable ANR. Sound quality of music and voice.
Cons: Price... I believe if these headsets were a littler cheaper they sell many more. Headset Control Unit is a little bulky.
Review: I am happy I bought this headset. I struggled between the S1 digitial and the BOSE A20, which most of my instructors have, but ater carefully reviewing the options chose the Sennheiser S1 Digital as my primary headset. The ANR is excellent and as good or better then Bose. I also like the smart update function which allows the headset to adjust to the ANR aand the built in Bluetooth.

Great Headset!
by Clarisse from Warren, NJ 

Pros: Comfortable, reliable, well-made
Cons: Bigger than the Bose
Review: It was between the Bose A20 and these and I decided on these. The quality of the headset is better and seems stronger and I liked the way they cover your ears. Very comfortable to wear and the noise canceling does a great job.

by A Customer from Winnipeg MB Canada 

Pros: Unrivaled noise canceling and comfort.
Cons: Eye glasses feature non existent.
Review: I am training on a travel air, and fly frequently in a caravan. I can tell you these cancel more noise than any Zulu or Bose. Not to mention the sound quality when listening to music is great. The only con I can think of is the so called soft area for eye glasses are pretty much non existent.

Like the treble feature
by Gary from Woodland Hills CA USA 

Pros: treble boost
Cons: Noise quick sampling button only on left side
Review: I debated between the Bose A20 and the Sennheiser S1. Both have great features which made a very tough decision. The treble boost pushed me over to the S1. I have old radios making some communications difficult to sort out with all the chatter and background noise. The treble boost help separate the voice from the bass noise and lack of dynamic radio frequency range. Noise canceling coupled with treble boost created a great combination and improved communications.

realy surprised
by alexandre from st jerome QC Canada 

Pros: ANR
Cons: little big

I buy the sennheiser and so far no complain. ANR is perfect, microphone work really good, clarity perfect, everything is great.  I was in between Bose A20 and S1, I try both of them and for the sound and ANR, I would say S1, but not by much.

Nice Headset
by Paul from Saint Peters MO USA 

Review: I like it. I don't have a lot of ANR background for comparison, but have worked with Sennheiser products as a sound engineer.  The button to reassess the current flight noise does make a difference, but it seems this could be done automatically. The mic boom is a bit short, and the advertised padding to accomodate glasses doesn't really make a difference. Otherwise, very nice.

Almost perfect

Pros: Design , light weight , Noisegard update button , nice fit , adjustable clamp force, clear sound , equalizer function
Cons: Price , Light "blowing" - high frequency sound

I m a professional turboprop pilot so I'm everyday exposed to high decibel noises. In general I'm quite happy with the S1, it fulfilled almost all of my expectation.  Especially the Noise Gard update button can be real useful.  There are 2 things that troubled me though.
I still can hear a light blowing sound, like the one which is heard at their web-page sound reduction demo.
And also, I haven't still found out about the warranty years in Europe.
Their customer service department hasn't given me a clear answer about it, which is very annoying, because the 5 year warranty is important to me.

As a general opinion I'm happy I got them.

by Marty from New Prague MN USA 

Pros: very good noise canceling
Cons: none yet
Review: My new S-1 are being used in husky amphib and it's very nice after 2-3 hr flight to get out and be able to hear right away instead of the engine drone ringing in you ears for the next couple hours.  They are very nice and would recommend them to anybody who flies noisy aircraft.

Nice craftsmenship
by D from Sevierville TN USA 

Pros: You could hear great !
Cons: It transmitted to much background noise. making it hard for others to understand me.
Review: Unfortunately, I have one of the noisiest aircraft you will ever fly in. This headset didn't work for me, because it transmitted too much background noise, from my Main rotor transmission right behind my head. This made it to hard for other pilots to understand me. Everything else about the headset was great, I could hear excellent. This headset would most likely work great in any other aircraft, other than something as noisy as mine.

Not as good as Lightspeed, better than Bose
by Phillip from Atlanta GA USA 

Pros: Good for people with large ears
Cons: Cosmetically undesirable
Review: It is a good product, but not great. Has large, comfortable ear cups and headband. Noise cancellation was good, but (here again) not great. Design is a bit clunky and doesn't feel tightly constructed.

Compared it against Lightspeed's new product and Lightspeed was clear winner.

Not all that
by Richard from Miami, FL 

Review: Its not a bad headset but you are much better off with a Bose A20 or maybe a Zulu. I tried it for about a week and was not impressed with the headset so I returned it and bought a Bose A20.
