Six microphones and transparency mode let you take calls or hear announcements without removing the buds, while IPX5 resistance handles sweat and light rain.

Questions about this item

How long does the 45-hour battery last when ANC runs continuously?

The 45-hour total playtime is measured with the charging case; ANC use will reduce single-charge duration below the case-assisted figure.

How much heat or noise do the earbuds produce during all-day wear?

In-ear earbuds generate negligible heat and no audible fan noise; the 13 mm drivers and 32-ohm impedance keep power draw low for comfortable extended use.

What must I already own to use the 36 custom EQ presets?

A smartphone or tablet running the companion app is required to access the 36 EQ settings and firmware features.
