    bardzo przyjazna jakość produktu
    szczerze mogę polecić amatorom sportów i nie tylko. Słuchawki dobrej jakości, dobrze przetwarzanie i odwzorowanie dźwięku.
    Po założeniu dobrze obejmują głowę i nie przemieszczają się nawet przy gwałtownych ruchach. Całość dobrze zabezpieczona w twardym blistrze i kopercie bąbelkowej. Odporne na uderzenia i fizyczne "znęcanie się" nad produktem. Dobry produkt w dobrej cenie. Porównywalne sprzęty w markowym sklepie słuchałem w cenie około (na start, bo były i droższe) 300 pln. Warto więc zastanowić się nad zakupem alfawize. Polecam.

    More of a novelty than anything
    The concept is interesting and is a nice talk piece.
    It works fine but the sound lacks any depth, so it's only for light background music.
    I use it in an open-space with my coworkers, and you can, listen to music and still hold a conversation with others and this is a real benefit. So overall it does have its niche purpose

    Товар соответствует описанию. Емкость аккумулятора соответствует. Вес 34 грамма. По моему мнению душка должна плотнее прилегать к голове, когда лежишь на подушки не удобно. Слушаю на минимуме, если правильно приложить наушники то громкости достаточно.

    Per il prezzo ottimo acquisto
    Le cuffie sono arrivate in un pacco ben confezionto, la scatola è integra e non presenta ammaccature. Le cuffie sono molto carine esteticamente. Le ho provato correndo sotto la pioggia e fanno il loro dovere. Tuttavia non vi aspettate una qualità dell'audio eccezzionale, ma a mio avviso sono ottime per fare attività sportiva.
