Sound is loud and headphones are comfortable
Bought for my mum. Headphones are very comfortable and soft and they swivel so the angle is adjustable. Mum is hard of hearing so sufficient volume was important. She says it's very loud and she likes them a lot.

Ottimo rapporto qualità prezzo.
Sono rimasto sorpreso dalla bontà della riproduzione sonora.Ottima riproduzione dei medi e dei bassi nonostante le ridotte dimensioni dei woofer.Visto il prezzo davvero contenuto sono un best buy.

Really good sound, easy set-up & use
Very good overall indoor/outdoor speaker for the price. Only negative is that it comes with cheap, thin-gauge speaker wire.

Great for biking
We bought these Bluetooth ear phones to allow my wife and I to talk to each other while riding our bikes. They work great. This type of earphone with a behind the ear clip is comfortable and doesn’t fall off.

But the coffee itself is good.
I was hoping for more of just the chocolate flavored ones as not big on hazelnut or caramel? But the coffee itself is good.
