Total Isotropic Sensitivity (TIS) is a commonly quoted specification in the mobile phone industry. This, like Total Radiated Power (TRP) is a parameter that depends on the antenna and the receiver (or radio) that make up the communication link. Synchronized, instant notification on iPhones, iPads, Android devices and laptops. Wireless sensor tags connect events in physical world, e.g. motion, door/window opened/closed, temperature or humidity exceeding limits, to your smart phones, tablets and any Web browsers anywhere in the world with Internet access. Sensitivity is the efficiency with which an earphone driver uses the power it receives to convert an electrical signal into an acoustical signal, resulting in clear sound without any distortion. Measured in decibels of sound pressure levels, it indicates the magnitude of loudness which can be achieved at a certain level of power from the source, usually 1 mili watt.

The Beyerdynamic Amiron Wireless are the best-sounding wireless headphones you can buy, period. Sound is spacious, detailed, and makes you want to rediscover your music library. A loudspeaker (or loud-speaker or speaker) is an electroacoustic transducer; a device which converts an electrical audio signal into a corresponding sound. The most widely used type of speaker in the 2010s is the dynamic speaker, invented in 1925 by Edward W. Kellogg and Chester W. Rice. Headphones originated from the telephone receiver earpiece, and were the only way to listen to electrical audio signals before amplifiers were developed. The transmitted signal eventually reach the receiver. There, results depend on the Receive Sensitivity of that device -- i.e., the minimum power required to handle arriving frames at a given link speed. Receive Sensitivity is a given characteristic of a 802.11 device and will vary across products.
