USB Dictation Microphone

The Philips LFH3500/00 is a USB dictation microphone built for professional voice recording. It connects directly to a computer and integrates a trackball for cursor control. The device is shaped for hand-held use during long sessions.

Suited For And Not Suited For

This unit suits users who need an all-in-one handheld device for dictation and navigation. It is not for buyers who want a standalone studio microphone, a separate headset, or a wireless solution. The fixed cable and integrated speaker limit placement options.

Microphone Frequency Response

The microphone captures audio from 200 to 12000 Hz with a sensitivity of -37 dBV and a signal-to-noise ratio above 70 dBA. A free-floating capsule and integrated pop filter reduce handling noise and plosives.

Questions about this item

Does the box contain everything needed to start dictating, or must a separate sound card or driver disc be purchased?

The SpeechMike Premium connects by USB and draws power from the port, so no extra sound card or driver disc is required; the 2.5 m cable is permanently attached.

The LFH3500/00 is the only model listed — are there alternative capacities or versions to choose from?

Only the LFH3500/00 in dark grey pearl metallic is offered; there are no other capacities or colour variants in this range.

What does the 200–12000 Hz frequency response mean for everyday dictation quality?

It captures the full speech band from low fundamentals to high sibilants, while the free-floating capsule and integrated pop filter keep the signal-to-noise ratio above 70 dBA for clean transcripts.
