Panasonic launches its latest TWS earbuds, complete with noise-cancelling variants

Panasonic has waded into the 2020 TWS earbud market with what are essentially 3 variants of the same product. The RZ-S300W may be their 'base model', yet they feature a "stylish yet compact" design, touch controls and voice assistant support. They also have "high-performance" micro-electromechanical system (MEMS) microphones within their "unique labyrinth cabinet structure" for clarity during calls.

The RZ-S500W also leverage their extra "beamforming technology" to further improve on voice quality. This feature, which is based on dedicated forward- and backward-facing sensors, also confers "Dual Hybrid" noise-cancellation on these buds. They also have an Ambient Sound Mode for more environmental awareness during playback. 

This setting leaves the RZ-S500Ws with an estimated 6.5 hours' worth of on-time, which is augmented with another 19 hours from their case. The S300W buds have the edge here, with 7.5 hours of playback per charge or up to 30 hours more in their own case. These new accessories are also the cheapest of the three: they are US$119.99, whereas the noise-excluding variants are $179.99. 

Both are available in the industry's virtually stock black or white, although the RZ-S300Ws also have the option of a more unusual green shade. The Technics EAH-AZ70W, on the other hand, come in black or silver. These buds come with the RZ-S500W's marquee specs, and also pack 10mm dynamic drivers with graphene-treated diaphragms.

They are also larger TWS earbuds thanks to their Panasonic-engineered Acoustic Control Chamber, present to deliver this brand's "energetic yet rich sound". This top-end model goes for $249.99. All of these new audio devices are available from now from the OEM's authorized retail partners.
