## Before you buy

- Listing details conflict: the title and feature text describe over-ear headphones with memory-foam ear cushions, but the details table calls the ear placement and form factor “Open Ear.” The Bluetooth title says 6.0 while the technical field lists version 6. Battery life is mode-dependent, with up to 120 hours claimed ANC off and up to 70 hours ANC on. Confirm the selected listing’s fit and Bluetooth specification before buying.

## A good fit for

- Listeners prioritizing long claimed battery life, especially with ANC off.
- Commuters or desk users who want ANC and a transparency mode, provided the fit matches their needs.
- People switching audio between a phone and laptop, based on the listing’s dual-device connectivity claim.

## Less suited to

- Buyers who need water resistance.
- Anyone who requires a confirmed conventional over-ear fit or a precise Bluetooth version without resolving the listing inconsistencies.

## Customer feedback

The supplied evidence contains aggregate ratings but no written customer feedback. The ratings skew positive in a relatively small sample, but they do not identify praised features or explain individual experiences. They cannot resolve the listing’s conflicting description of the fit or verify its battery claims.

## Frequently asked questions

### How long does the battery last?
The feature listing claims up to 120 hours with ANC off and up to 70 hours with ANC on. These are separate mode-specific claims, not one unconditional runtime.
### Does the listing confirm an over-ear fit?
Not consistently. The title and feature text describe over-ear headphones, while the details table lists “Open Ear” for both ear placement and form factor. Confirm the fit on the selected listing.
### Can the headphones connect to two devices at once?
The feature text claims dual-device connectivity, with a phone and laptop connected at the same time. The listing describes switching between them, rather than simultaneous audio playback.
### Are they suitable for use in rain or workouts?
The listed water-resistance level is “Not Water Resistant,” so the provided details do not support choosing them for wet conditions.
