Jabra Elite 8 Active vs Elite 4 Active

Elite 8 Active has a higher IP68 rating for better water and dust resistance compared to Elite 4 Active's IP57 rating. It also cancels out noise 1.6x better than Elite 4 Active. Another advantage it has over the Elite 4 Active is Bluetooth Multipoint, which allows you to connect to two devices at once.
The newest earbuds may not always be the one you need. Sometimes, the older models may be more cost-effective and good enough for your needs.
