Here are the some differences between Buds 2 Pro vs Buds 3
Galaxy Buds 2 Pro uses a dual-driver setup with dynamic drivers, the Galaxy Buds 3 Pro uses an improved dual-drive setup featuring planar drivers. Planar drivers usually have higher details, more control, and a wider soundstage.
The Galaxy Buds 3 Pro also uses a higher-quality audio codec called Samsung Seamless Codec Ultra High Quality (SSD UHQ) with a 24-bit 96KHz sampling rate, which is twice as good as the 24-bit 48KHz Samsung Seamless Codec Hi-Fi (SSC Hi-Fi) used in the Galaxy Buds 2 Pro.
Buds 3 also feature Bluetooth 5.4 for higher privacy and security.
Galaxy Buds 3 Pro have microphones closer to the mouth, allowing the voice to be recorded more clearly.
Buds 3 features Super Wideband (SWB) call, which records audio in a wider bandwidth of 16KHz for more natural sounding calls.
The Galaxy Buds 3 Pro have an IP57 rating for dust and water resistance, an improvement over the IPX7 Rating
I have observed that the fitting of buds 3 not well as the operate touch makes dislocation and chance are much higher it can fall off I have tested it in unpacked event
