In the crypto hardware wallet market, clarity of on-device transaction verification and asset recovery after loss are emerging as key selection criteria, beyond the number of supported coins. Cointelegraph compared major wallets by security, connectivity, usability and recovery options. Differences were notable in input experience and screen design. Wireless, wired and QR-based models offer varying trade-offs, but none guarantees safety if users approve malicious transactions or leak backups.

Major audio makers including Apple, Sony and Bose rolled out new headphones and earbuds throughout September, intensifying competition in the portable audio market. Products ranged from lower-priced models to premium offerings, highlighting differing strategies. Apple unveiled two AirPods 5 models and added a Beats 360 variant. Sony refreshed three headphone models. Sonos emphasised ecosystem connectivity, while Bose introduced a $99 wired earbud with ANC. Nothing and Technics launched premium over-ear models late in the month.
