Question: Do these headphone cups pivot?
Document: This headphone has good quality sound and comfortable ear cups that encompass the whole ear. It has excellent bass but it is lacking in overall volume. The only things I would change on this headphone are to add a volume control in the cord and add a pad on the headpiece which can get to be irritating with extended listening.
This is an amazing set of headphones. Its a great buy at only $14. it just gives powerful sound that is of exquisite quality. It cups the ear perfectly and the cushion is so comfortable.
very acceptable for the price . head top band uncomfortable, ear cups just big enough for my smallish ears. whole thing fit my big head very comfortably
while the sound quality is decent, these headphones aren't isolation headphones. They have large earcups, but the foam sealing rings do not block much outside noise. The speaker cups are also externally vented, which allows ambient noise in.
Great for price - ear cups sufficiently large. I was going to get the similarly priced Sony, but people said the Sony ear cups were too small on them so I went with these and they are indeed larger and cover my ears.
The reviews were so good on these earphones and the price was incredible, so I thought I'd try them. Just awful! The bass was so loud, it drowned out everything else. The ear cups are huge, and they hurt the top of my head. I guess you get what you pay for!
The ear-cups fit nicely over the ears and these headphones are comfortable, but the sound quality, in my opinion, is poor at all levels--highs, mids and lows. I am no audiophile or anything, but lately I've been looking for some decent and inexpensive headphones. I suppose these are decent for the price, but I think the sound quality is lacking.
It's hard to say because there are some plastics that are so pliable that you couldn't break them if you tried. But, there is really no way to know that ahead of time. The other pieces of the headphones that concern me are the hard plastic pieces where the ear-cups attach to the head-band. These are a hard plastic which I have concerns about breaking. I've had full size, high quality, expensive gaming headphones break in this same spot before.
These are very decent headphones with clean treble and deep bass, large ear cups that fit over lobes that cancel outside noise very well, and overall exceptionally clear audio. There is no hiss, no crackle, no muddy sounds at all. People will need to adjust their music player equalizer for each type of music you are listening to, or type of movie, game, etc., as this will affect sound clarity.
Firstly, a list of pros and cons:PROS:-Comfortable. These things have large circular cups which will fit over even the largest of ears. I am a pretty large guy with a big, fat head, and these things fit me perfectly. The cord is also about eight feet long, which is nice.-Cheap. Cheap as dirt. These phones are decent for the price you pay for them. However, remember, "You get what you pay for."
Answer: There are the two upside down U shaped brackets that connect the ear cups to the head strap. The ear cups themselves pivot (up and down) in that U shapped bracket but the bracket only rotates (slightly) at the joint where the bracket meets the headstrap.  I would say that there is maybe 30 degress of rotation that the bracket can travel through at that connection point.  It's enough to make sure that the cups rest comfortably over the ears and against the side of the head.  The point where the braket meets the head strap only rotates itdoes not really pivot.  The cups will not fold up into the area beneath the head strap like some more expensive folding headphones. I hope this helps.
