Panasonic's latest earbuds come in ANC and non-ANC varieties. Both options are IPX4-rated "canal style" wearables - or AirPod clones, in other words - although the new RZ-B310W accessories have a more, customized, angular look compared to the more basic RZ-B110Ws.
Then again, the lower-end models have the edge in terms of battery life, rated for up to 26 hours from their individual batteries (6 hours) and USB type-C charging case (the remaining 20), compared to up to 16 hours (11 of which require the case) in the RZ-B310Ws.
Both sets of earbuds also support Panasonic XBS tech for their 10mm drivers, as well as Google Assistant or Siri. Either new Panasonic product comes in just 1 black finish option and with the up-to-date Bluetooth 5.3 standard.
Nevertheless, the RZ-B310W buds are now priced at US$99.99 on Amazon, whereas the have an MSRP of US$59.99, thanks to the former's hybrid (feed-back and feed-forward with both external and internal mics) ANC spec.
