## Before you buy

- Battery claims vary by use: up to 100 hours of playback with ANC off and 50 hours with ANC on. The listing also gives a 120-minute charge time and says a full charge takes under 2 hours, so charging-time details are inconsistent. It lists a 3.5mm audio interface and an included 3.5mm-to-3.5mm cable while also stating No Jack. Check how wired audio connects before buying, and treat the water-resistance claim as unspecified beyond the wording shown.

## In the box

- 3.5mm-to-3.5mm audio cable \(1.2 m\), quantity 1 (Included)
- Protective case (Included)
- User manual (Included)

## A good fit for

- Listeners who want over-ear Bluetooth headphones with both ANC and transparency modes.
- Buyers prioritising long stated playback, provided they note the shorter claim with ANC enabled.
- People interested in LDAC, spatial audio modes and app-based sound adjustments.

## Less suited to

- Buyers who need an unambiguous wired-connection specification or a clearly stated water-resistance rating.
- Anyone expecting the maximum 100-hour playback claim while using ANC, as the listing gives 50 hours for that mode.

## Customer feedback

Customer feedback highlights perceived sound quality, comfort, battery life and ease of use, with positive comments also describing ANC and transparency settings as working well. Some customers mention a roomy fit for larger heads. These impressions align with the listed over-ear design and mode-specific battery claims, but feedback does not establish measured battery or noise-cancelling performance. The aggregate ratings are mostly five-star, with a meaningful spread across lower ratings, so experiences are not uniform.
- Positive themes: Customers report good sound quality, comfort and battery life.
- Positive themes: Feedback praises fit, ease of use, and ANC and transparency settings.
