What to know before buying

Listing details to confirm

The listing gives inconsistent frequency information: one detail states 21 KHz, while another states 20Hz - 20,000Hz and a feature states 5 Hz – 21,000 Hz. The listed 28-hour battery total is also broken down elsewhere as 8 hours from the earbuds plus 20 hours from the case. Treat these as listing claims and confirm which specifications apply to the offered version.
