## Before you buy

- Listing details conflict or remain unconfirmed: it claims IP54 water and dust resistance in the feature text, but the specification says “Not Water Resistant”. The title states 42dB ANC and 35.5 hours, while the details separately list 42 dB sensitivity and 35.5 Hours for case battery life. Treat the claimed ratings and runtime as listing information, not verified performance. The feature text also describes USB-C case charging, though that connector is not otherwise specified.

## A good fit for

- Listeners wanting in-ear Bluetooth earbuds with active noise cancellation and a transparency mode.
- Buyers who want app-based adjustment and custom EQ options, as described in the feature text.
- People considering earbuds for calls, noting the listing's microphone and wind-noise-reduction claims.

## Less suited to

- Buyers who need confirmed water resistance, given the conflicting protection information.
- Those prioritising dependable long battery life or long-term durability, as customer feedback raises concerns in both areas.

## Customer feedback

Customer feedback is broadly positive about perceived quality and noise cancellation, but sound quality, reliability, comfort and value receive mixed reactions. Battery life and durability draw criticism, including reports of around four hours of use and some units stopping after two months. That matters alongside the listing's 8-hour earbud and 35.5-hour with-case claims, which are not a guarantee of individual results.
- Positive themes: Customers describe the earbuds as good quality.
- Positive themes: Customers appreciate the noise cancellation.
- Negative themes: Battery life and durability are criticised, including reports of short runtime.
- Mixed feedback: Sound quality, reliability, comfort and value receive mixed feedback.
