Where is it heading?
The audio utility market is shifting toward hardware-integrated software, making the 3,600+ headphone profiles a critical asset for long-term retention. Equalizer + Volume Booster is well-positioned to serve users who own multiple headphone brands, provided it continues to expand its database faster than individual manufacturers can build their own proprietary solutions.
