A bizarre concept, really: a microphone in your ear with a cable attached. That is basically what the Philips LFH 9162 is, however, and as such it enables you to record phone conversations with a voice recorder!
This table microphone is ideal for recording meetings. It will record all important discussions that you might want to replay some time later. It has a range of 360 degrees, with a radius of two metres.
The LFH 9171 is a unidirectional electret condenser microphone. It can easily be used in combination with various types of voice recorders, turning them into great interviewing tools. The LFH9171 picks up sound from one direction.
