Summary: I bought these cheap headphones for the kids, not expecting much in terms of sound quality. I should have been more worried about build quality however. As mentioned, the rotation hinges on a tiny plastic nub which wears and breaks easily. I ended up supergluing the ear pieces to the head piece to prevent them from falling or breaking off.
Pros: Good price, decent sound.
Cons: The swivel feature design is a complete bust. The ear pieces rotate around a cheap plastic 'nub'. After a few rotations, the piece is worn enough that the ear pieces constantly fall out of the sockets. After snapping them back in multiple times, the cheap plastic couldn't take it anymore and broke.
Summary: When I first used the earbuds that came with this package, I was surprised when I noticed how much bass they had compared to other earbuds that are about two or three times more expensive than this combo. As for the headset, I don't have any complain. Overall a good sound quality except for the mediocre low frequencies. I bought this as a temporary replacement for my dead Turtlebeach x11 and honestly, I was amazed at what Coby had to offer at less than 12 dollars.
Pros: -Very affordable -Light -The earbuds have a surprisingly good bass.
Cons: -Construction is a little weak at bending points.
Summary: Kopfhörer und Earplugs in einem zu dem Preis ! Bin kein FAN von Earplugs und habe das erste mal diese mit der Gummiblase um den Earplug. Tragen sich wirklich angenehm und rutschen selten raus. Klarer Tip. Sound für meine einfachen Ohren , ausreichend laut !. Klapp Kopfhörer , seltsme Mechanik, jedoch tragbar wenn erst mal richtig angepasst. Drückt zum Anfang leicht und schottet hermetisch gegen Umgebungsgeräusche ab.
