Current note: MobileConnect is not affected by the recently discovered and discussed log4j vulnerability (CVE-2021-44228).



MobileConnectは、以下にあげる3つの主要コンポーネントで構成されています。MobileConnect Stationは、「オーディオからネットワークへのブリッジ」として機能し、部屋の音声信号を受信し、任意のネットワークにストリーミングします。信号は、既存のWiFiアクセスポイントを介し、MobileConnectアプリをレシーバーとして、ステーションあたり最大100台のスマートフォンに提供されます。複数のステーションを使用する場合には、すべてのMobileConnectステーションに対する唯一の管理ポイントとしてMobileConnect Managerを使用できます。MobileConnectは、必要がない場合、いわゆるスタンドアロンモードで運用することも可能で、このモードでは、ローカルのウェブインターフェイスを使用して単一のMobileConnectステーションを運用および管理できます。

特に、複数のMobileConnectステーションを使用する場合、リモートでのシステムの把握にはMobileConnect Managerが役立ちます。また、MobileConnectは、貸し出し機器の清掃や提供、バッテリーの充電といった面倒な作業を排除し、重要なことに集中するのにも役立ちます。 チャネルアクセス用の新しいQRコードの提供まで、MobileConnect APIを使用してミーティングのカレンダーに簡単に統合できます。

Our success stories


  • What application is MobileConnect made for?

    • The main application of MobileConnect is assistive listening.

      The aim is an uncomplicated and full inclusion of people hard of hearing. The “Bring-Your-Own-Device” concept brings the audio stream directly to a user’s personal smartphone making it easily accessible and intuitive to use. The two biggest benefits are that the person hard of hearing does not have to ask for a specific receiver device and that this person can sit wherever the WiFi is.

      Besides assistive listening the system can also be used for interpretation applications because it is scalable in terms of provided audio channels.

  • How does it work?

    • The MobileConnect Station works as an audio streaming server within the network. It picks up an audio signal (XLR or DANTE) and bridges it to a LAN for being further distributed via WiFi to the personal smartphone running the MobileConnect app (iOS & Android).

  • How many end-users can listen to an audio stream simultaneously?

    • One MobileConnect Station supports 100 simultaneous listeners. This means either 100 listeners for one channel or in total 100 listeners for two channels per Station, e.g 60/40 or 80/20.

      The MobileConnect system is highly scalable and so multiple MobileConnect Stations can be used at the same time if more simultaneous listeners or audio channels are required.

  • How many audio channels are available on one MobileConnect Station?

    • Two channels (Mono or Stereo) are available. The audio signal can be fed into analog (XLR) or via DANTE.

  • Is Sennheiser MobileConnect ADA compliant?

    • Yes, read our full statement on ADA compliance here.

  • How can it be integrated into my auditorium, venue or meeting room?

    • The most simple integration setup is shown in the picture below - the so called “Standalone Mode”. An audio source is connected to the MobileConnect Station via DANTE or XLR analog. The MobileConnect Station is connected to the WiFi network over the “PoE/Stream” LAN port.

      The local Admin interface for configuration can be reached over the “Ctrl” LAN port from your browser at the address .

      As soon as the MobileConnect app on a smartphone scans the QR-Code it will establish a streaming connection to the MobileConnect Station and so will receive the audio content.

  • Does the system provide a WiFi network?

    • No, the WiFi network needs to be in place. Detailed WiFi requirements can be found here.

      If you want to set up a dedicated WiFi network for Sennheiser MobileConnect, please contact a professional IT integrator.

  • How does the end-user listen to the audio stream?

    • To activate the audio stream via the MobileConnect app, the end-users smartphone must be connected to the same WiFi where the MobileConnect system is integrated in.

      The end-user can connect to a location specific audio channel by the following three methods:

      1. browsing the channel list within the app (if not hidden)

      2. scanning a specific channel QR-Code

      3. typing in manually a channel ID

      Lastly, the end-user can listen to the audio stream over wired headphones that are connected to the smartphone. It is also possible to listen directly over the hearing aids or the cochlea implant in T-Position with the combination of an induction neck loop that is connected to the smartphone.

  • Is there a delay/latency in the audio transmission?

    • The following latency can be expected with the system:

      - On iOS devices the latency is 50-55ms

      - On mid-range to high-end Android devices (Wifi 5/ac & Android Version >9) the latency is 50-65ms

  • Which smartphones are recommended to use with MobileConnect?

    • In terms of Android we recommend to use mid-range or high-end devices that support Android Version >9 and WiFi ac. For iOS we recommend all devices that support iOS version >13.

      In the following you can find a list of selected devices that we can recommend in terms of audio stability and latency:


      iPhone 8 - present

      iPod Touch (7th Gen.)


      Google Pixel 3 - present

      Samsung S-Series 8 - present

      Samsung Note Series 8 - present

  • Which headphones do you recommend, and which induction neck loop do you recommend?

  • Is it also possible to use headphones or hearing aids connected via Bluetooth?

    • Yes, this is possible, but the current Bluetooth technology (< Version 5.2) does not provide ultra low latency audio transmission. This means that with Bluetooth connection the audio transmission won’t be lip-sync.

  • What if the smartphone does not provide a 3.5 mm headphone jack?

  • Can I customize the app with my own logo or color?

    • No.

  • Is there an SDK (Software Development Kit) for implementation into my own app available?

    • No.

  • Is the receiver app available as a browser add-on?

    • No, the app is only available for iOS, MacOS (M1), iPadOS and Android devices.

  • Is it possible to secure an audio channel?

    • Yes, it is possible to change the QR code / Channel ID of a channel at any time. After a change, each current listener will be disconnected from the channel and can only log in again with the newly created QR code / Channel ID.

      In addition, it is also possible to set a dedicated PIN code for each channel.

  • Does the system require an internet connection?

    • The MobileConnect system itself only requires internet connectivity when it is used in the so called “Manager Mode” because the MobileConnect Manager handles the authentication and updates over the cloud.

      In “Standalone Mode” the MobileConnect system does not require an internet connection.

      For the end-users smartphone we recommend to offer an internet connection on the WiFi-side because some smartphones will automatically disconnect from a WiFi that is not providing internet connectivity and this will lead to audio dropouts.

  • Can I use my old CinemaConnect system with the new MobileConnect App?

    • Yes, the MobileConnect App supports CinemaConnect systems including subtitles.
