What to know before buying

Listing details to confirm

The listing gives inconsistent weight and size details: 347 Grams and 6D x 12W x 10H centimetres in product details, versus 330g and 147(L) x 75(W) x 96(H) mm in feature material. The title and details state 5W, while feature copy also refers to 10W peak dynamic power. Treat the stated up-to-6-hour battery life as a claim, not a guaranteed duration.
