The Ear 2 features polyurethane components for clearer low frequencies and graphene for brighter highs. The buds have a dual-chamber design for a wider soundstage and are compatible with Hi-res audio and the LHDC 5.0 codec. While the Ear 2’s sound quality is better than the Ear 1’s, it does not match the quality of more expensive wireless earbuds.
The Ear 2 also features three levels of active noise cancellation (ANC) and a personalized ANC profile calibrated to the user’s hearing. However, the ANC struggles with the reverberations on trains and the subway, leading to a jarring noise echo in the left bud while using ANC, despite recalibrating the buds several times in a bid to fix it.
