Audio Conferencing Endpoints – Product Details & Advice
Audio conferencing endpoints (conference speakerphones) are dedicated audio devices for multi-party conference calls in conference rooms or home offices. They offer 360° microphone coverage (omnidirectional microphone arrays), AEC (Acoustic Echo Cancellation) and NR (Noise Reduction) for clear speech intelligibility even in lively environments. Connection: USB-A/-C (plug-and-play for PC/Mac), Bluetooth (smartphone pairing) or combined. Best-known models: Jabra Speak 750 (single/duo), Konftel 300Wx, Poly Sync 40, EPOS EXPAND 40T.
Extension microphones and accessories: Audio Conferencing Accessories. Video conferencing: Video Conferencing Endpoints.
Frequently Asked Questions
▶ How many people can conference with one speakerphone? Rule of thumb: standard speakerphone (e.g. Jabra Speak 510/710): 4–6 people, microphone range 2.5–3 m. Speakerphone with extension unit (Jabra Speak 810 + extension): up to 8–12 people, 7 m range. Dedicated room conference system (Polycom RealPresence, Shure MXA microphone array): up to 20+ people in boardrooms. |
▶ What is the difference between a speakerphone and a conference phone? The terms are often used synonymously. In the strict sense: speakerphone = USB/BT device without its own telephone connection (only for PC/softphone use). Conference phone = device with its own SIP/ISDN/DECT connection for direct telephone operation without PC (e.g. Yealink CP960, Poly Trio). Hybrid devices (e.g. Jabra Speak 750) support both. |
▶ Sound differences between USB and Bluetooth connection? USB connection typically provides better controlled audio quality (no wireless interference, lower latency, no codec compromise). Bluetooth connection offers more flexibility (no cable, smartphone pairing), but can be marginally worse due to WiFi interference (2.4 GHz) and latency (20–100 ms). For critical presentations: USB. For spontaneous small meetings: Bluetooth is sufficient. |
