The fit-friendly app option.
The split-wing shape is the useful idea here. Instead of forcing every buyer into one fixed tunnel, the open silicone sides can flex and be squeezed by hand for more pressure. Fourteen built-in modes also mean the product is still usable without opening an app every time.
The app expands control with custom patterns, music syncing, and long-distance play. That sounds worthwhile on paper, but Bluetooth reliability, account setup, privacy, and whether the custom modes feel meaningfully different all need real testing.
