Product Description


Also available in BLACK



The Pioneer S9 features active noise-cancelling technology to immerse you completely in music without interference from surrounding noise. Further, Ambient Awareness Mode allows the right amount of sound in from the outside world. With a newly featured Assistant button, you can skip or pause songs, get notified about new messages, and search via voice control without pulling out your smartphone. Bluetooth® technology supports Qualcomm® aptX™ HD audio*, enabling high playback quality with the freedom of a wireless connection. Thanks to a built-in high capacity battery, continuous 24-hour music playback is possible—great for long flights. Premium finish with aluminum housings and use of textured, comfortable materials add a quality accent to your everyday style.

* Playback with the Qualcomm® aptX™ HD audio codec requires Qualcomm® aptX™ HD audio-compatible device.


Onkyo & Pioneer (Sumida-ku, Tokyo, President & CEO Kenji Miyagi) has unveiled the luxurious S9 wireless noise-cancelling headphones (SE-MS9BN) optimised for the Google Assistant*2 and Hi-Res Audio*1 to its Scene Style Series and fit your preferred style scene. The S9 features large Φ 40 mm (1.57-inch) rare-earth-magnet drivers to enable Hi-Res Audio reproduction, and the headphones support Qualcomm® aptX™ HD audio*3 for pristine playback liberated by the freedom of a wireless connection. Designed to work seamlessly with the Google Assistant, these high-value features elevate the S9 to premier status among Pioneer’s Scene Style Series products.



Relax with easy wireless music and hands-free conversation on smartphone. Buttons and mic on the headphone housing to allow the listener to easily adjust the volume, skip tracks, and take calls*. The S9 also features NFC functionality for instant device pairing. Maximum continuous transmission of 27 hours (NC OFF/including music playback time) extends entertainment between battery replenishment.

*Some functions may not be supported depending on the smartphone.



Continue your conversations while on the go and easily access the best of Google, from Google Play Music to Google Maps. You can quickly enjoy entertainment, stay connected to friends, get information, and manage your day all without glancing at your phone. Listen to your favorite songs, have notifications and messages read to you, or set reminders and timers. Just press and hold the button to start a conversation with your Google Assistant.



The S9’s large Φ 40 mm (1.57-inch) rare-earth-magnet drivers provide excellent bass extension and wide frequency response, capturing the expanded dynamic range of Hi-Res Audio when connected to a compatible player via the supplied headphone cable. Powerful Copper-Clad Aluminum Wire (CCAW) voice-coils enable clean and accurate sound throughout the audio spectrum, from deep bass notes to crystalline highs.



In addition to AAC and Qualcomm® aptX™ codecs, the S9 supports Qualcomm aptX HD audio codec, allowing users to enjoy HQ wireless playback without need of a cable connection. Listeners are assured of deep, clear, and spatially convincing sound for a musically satisfying experience.



The S9 fills the mind with music while virtually eliminating external noise, which is distracting and detrimental to audio quality, particularly low-frequency noise from jet engines or subway cars. Active noise-cancelling technology detects external sounds and generates frequencies in opposing phase to cancel them out. In situations where some outside sound is desirable, Ambient Awareness Mode filters it in for improved situational awareness.



Multi-point Function allows two smartphones to be wirelessly connected at the same time. Take calls with one phone and listen to music with another. This presents an easy-to-manage solution for people with work and private phones.



Developed exclusively for Pioneer headphones, the new and expansible Pioneer Headphone App* brings a host of functions to the listener’s fingertips. The app supports Bluetooth pairing, the ability to switch noise management modes, and more. Plus, Pioneer plans to add new functions via app updates in the future, which promise some exciting features for music lovers.

*Functional with a wireless connection only.




Pioneer takes comfort to a new level with the S9. To maximise immersion and ease stress, weight is evenly distributed with a wide polyurethane-cushioned headband. A balance of flexibility and firmness is achieved with sliding hangers and low-profile, low-repulsion earpads that surround the ear and properly align with the head. The result is exceptional comfort over long listening periods.



The S9 pays tribute to Pioneer’s hi-fi pedigree with tastefully blended retro-modern style burnished by aluminum housings available in a beautiful silver-accented black. The headphones mark the wearer as someone who appreciates hi-fi sound while embracing the benefits of next-wave technology, all in a product that’s constructed and finished to the highest possible standard.



Many smartphones, DAPs, and hi-fi components support Hi-Res Audio output, so it’s great to experience improved sound quality on the S9s without compromise. Just connect the cable to let its large drivers air the expanded dynamic range of Hi-Res Audio*. Even with the suggested 27-hour playback time**, it’s good to continue listening via cable should the batteries become depleted.

*With wired connection
**With Bluetooth connection, NC OFF, including music playback time.
