Which one fits you
On wrists narrower than about 60mm, the TalkBand B3 is the safer pick — it stays proportionate down to roughly 45mm, where the TalkBand B6 starts to hang over the edge. Above 60mm both sit cleanly, and the TalkBand B6 gives you more presence.
The TalkBand B6 wears larger than the TalkBand B3 (22.6mm vs 21.7mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
