If you have a Windows notebook, it might have been shipped with some APOs (Audio Processing Objects) by the vendor. Typical names are “DolbyDAX” or “MaxxAudio”. These APOs “optimize” the sound by introducing filters and compressors into the signal chain to make audio sound “better” through your notebook’s speakers. But they also mess with headphone audio and lead to a severe degradation of the audio quality in my opinion. As far as I know, there is no user-friendly way to turn them off. And even if you manage to turn them off, chances are that they are back with the next bi-annual Windows 10 feature update.
I recently bought the new Beyerdynamic Lagoon ANC headphones. They come with MOSAYC sound personalization. This feature is advertised as follows:
Our sense of hearing is unique and changes over the course of our lives. Like a mosaic, some pieces of the sound picture get lost or they fade. The unique MOSAYC sound personalization by Mimi Defined™ compensates exactly this development and adjusts itself precisely to your hearing ability. With individual sound personalization, the missing tiles of the mosaic are restored. And you can enjoy the full sound picture in all its colourful splendour.https://north-america.beyerdynamic.com/mosayc
Although I really like speakers and headphones with absolutely no sound “enhancements” turned on (DELL and HP laptops, anyone?), I was intrigued by the idea of getting my very own personal sound, so I gave this feature a try and this post is about what I have found out.
Please bear in mind that this post is NEITHER about the quality of the headphones themselves nor its Active Noise Cancellation (ANC) feature. I personally think they are both great. This post is only about the sound personalization feature.
