They look way too similar to not be the same: pcb, color of dots, white substance to hold coil wires, even the damping mesh looks the same. However, they might sound different due to the foam used on the vents on the back casing, or should I say 2 horizontal lines. This foam is probably denser/thicker on one of them. This wouldn't be the first time that earbuds use same drivers but are tuned differently + have different cables. Tuning has a greater effect on earbud drivers than people suspect.
