Summary
Sennheiser's five-page data sheet for MobileConnect, a system that streams venue audio over Wi-Fi to an app on listeners' own phones.
Key findings
- Gives the app's latency as "40-60 ms on average" and the station's capacity as 100 simultaneous clients.
- Describes a bring-your-own-device system that works through the venue's existing Wi-Fi network, with listeners hearing the stream through personal induction neckloops, headphones or hearing aids.
- Its architect's specification says the system shall support all wireless and wired headphones, hearing aids and cochlear implants, and that each central unit allows up to 100 users.
- Page 2 places the 40 Hz-20 kHz response, 101 dB(A) signal-to-noise ratio and -82 dB(A) THD+N under the XLR connectors heading. These figures do not specify a measured phone-to-ear listening path. The sheet does not name the live streaming codec.
Limits
A maker's data sheet: the latency is an average with no stated method, phones, network load or listening path (wired, neckloop or Bluetooth), and the capacity is given per station without network conditions. No date is printed; the year comes from the PDF's creation date (16 January 2023). Sennheiser's MobileConnect product page linked this version on 9 October 2026.
