M4

A base-model speakerphone for portable conference calls

The AISPEECH M4 is a self-contained conference speakerphone for people who need to join or host calls away from a fixed meeting room. It measures 112.5 mm by 112.5 mm by 35.4 mm and weighs 236 g, so it fits in a bag beside a laptop. The M4 is the base model in the range, and its main difference from the M4 Pro is the absence of directional pickup. The rest of the listed specification is shared with the M4 Pro, so the choice comes down to whether your meetings need that feature.

Microphones, speaker and noise control

Four omnidirectional MEMS microphones pick up voices from every direction around the unit, with a stated frequency response of 100Hz to 10kHz. The speaker covers 100Hz to 20kHz in music mode and 150Hz to 7.5kHz in call mode. Its speaker specification lists a rated output of 8W x 2, alongside a 5W output figure. On the processing side, the M4 suppresses background noise by up to 35dB, supports bilateral noise reduction and uses intelligent automatic gain control to keep voices at a steady level. AI reverb suppression reduces echo from hard surfaces, and AI full duplex lets a participant interrupt a speaker without the call stalling.

Connecting by USB, Bluetooth 5.1 and NFC

The M4 offers three connection types: USB, Bluetooth 5.1 (BT5.1) and NFC. USB suits a laptop at a fixed desk, Bluetooth pairs a phone or tablet without cables, and NFC allows quick pairing with compatible devices. The unit is powered by a USB 5V/2A source and includes a 2000mAh built-in battery. The manufacturer data does not state battery runtime, so ask for that figure before planning long sessions away from power.

Where it fits across Qatar

• Site offices in the Industrial Area or Mesaieed: a supervisor joins a call with head office in Doha from a field office, with the speakerphone on a table instead of a fixed system.
• Hotels and serviced apartments in West Bay or The Pearl: a small meeting corner where guests join calls with colleagues abroad without fitting out a full room.
• Government and ministry teams: a working group in a shared Doha office holds short meetings with colleagues in other locations during the standard working week.

What to plan before you order

Because the M4 is portable, placement matters more than mounting. Set it on a table at the centre of the group, away from air-conditioning vents where possible. The manufacturer data does not list an operating temperature range, so confirm the intended environment with the SmartRooms Qatar team before using it in a vehicle, an outdoor tent or an unconditioned space, where summer heat and dust in Qatar are a concern. Quotations are usually issued within one working day, and we deliver to all eight municipalities of Qatar. Purchase orders (LPOs) and government tenders, including Monaqasat, are supported, and payment can be made by bank transfer, cheque or purchase order.
