Since 1977, Meridian have been crafting innovative, elegant, high performance audio solutions. As the British pioneer of high-resolution audio and a leading authority on Digital Signal Processing (DSP) they transform the way people experience sound, wherever they are. Since their inception more than 40 years ago, Meridian's rigorous and research-led philosophy has maintained their position on the limits of what's possible in sound. As the Pioneers of High Resolution Audio and Masters of Digital Signal Processing (DSP), Meridian have played an integral role in the development and adoption of pioneering technologies. Meridian are the masters of Digital Signal Processing (DSP) and pioneered the concept of the DSP digital active loudspeaker with integrated amplification. DSP allows absolute control over the audio signal, enabling the design of advanced technologies that can enhance the listening experience in any context. Meridian have been a long-term collaborator and technology partner with Dolby. Meridian Lossless packing technology was developed by Meridian and licensed to Dolby as the standard for DVD audio. Meridian developed MQA - the revolutionary technology for efficiently streaming music with the highest possible sound quality. With MQA you can be sure that you’re hearing exactly what the artist approved in the studio. Meridian's Headphone Spatial Processing (HSP) overcomes the challenges of headphone listening such as their compact size and lack of 'crosstalk' between the left and right channels. HSP not only recreates a realistic soundstage that simulates the experience of listening to real loudspeakers, but it also delivers vocals with pristine clarity. This is a fresh listening experience helping you forget you are wearing earbuds. A 6mm custom-built driver unit optimises how you experience Meridian sound. This powerful yet compact unit promotes vocal clarity and intensifies rich bass.​ As well as the standard Immersive mode, you can choose three other presets enhanced with Meridian Headphone Spatial Processing (HSP). The close in-ear fit provides a remarkable seal that helps to block out surrounding noise, even when you’re in a busy café, noisy workspace, or crowded bus. A simple tap on your earbuds lets you be fully aware of your surroundings. This mode ​is useful when you need to have a quick conversation, pick up an announcement on ​public transportation, or cross a street. It’s a more convenient and safer way to enjoy music.​ LG TONE Free FN4 features built-in, high-performance dual microphones for maximal call clarity. Echo Cancellation and Noise Reduction, which is engineered with the leading beamforming algorithm of LG TONE neckband series, detects and minimises unwanted noise. And the lower microphone positioned at the end of the stem picks up and amplifies your voice even in a crowded space.
