If I recall correctly, the better form of bimodal stimulation was found by Susan Shore et al.[1][2][3]. Lenire created a quick and dirty version and got it approved, while Shore's device is still stuck in limbo.

If it ever gets approved, it should be considerably better than Lenire, but it's sure taking its time.
