Jabra has proven itself as a true wireless competitor with its Elite 65t earbuds in 2018, and the 85t's are a worthy successor. They deliver great ANC, ambient mode, Hey Siri support and a surprisingly comfortable fit. If you're an iPhone user though, Apple's AirPods Pro are still the best choice for a pair of earbuds. They have the smallest case, best battery life, ambient mode and the ability to be used with two devices simultaneously.
On the audio front, the Jabra 85t's have an excellent sound profile that balances bass, mids and highs well. The default EQ has a modest boost in the low frequencies to give the music some weight and substance without overpowering the rest of the mix, and that's an approach that I like a lot. The earbuds also reveal a lot of fine detail, so if you listen closely to a vocal performance you can hear the singer's character and commitment come through.
For active noise cancellation, the earbuds use 6 microphones (two per earbud) to detect and filter out external noise. They're a little less effective than Sony's XM4 earbuds, but they should be able to keep out distracting sounds such as engines and refrigerator hums.
Jabra has added Qi wireless charging to the 85t's case, which is compatible with any device that supports the standard. It's an easy way to top up the headphones while they're not in use, and the case can charge them for an hour in just 15 minutes.
