A:AnswerThe right earbud can be used by itself. The left earbud can not be used independently of the right earbud. The right earbud is paired to your device, and the left earbud can only be paired to the right earbud.
A:AnswerJaybird Vista is the way to go if you want jaybird. I would definitely lean towards Jabra elite 75T/ elite active 75T but If you want the best premium sound master & dynamic and or sennheiser momentum true wireless is your best premium earbuds in my opinion.
