Question: Do they work with a PC?
Document: I don't know why but it doesn't work with my kindle fire HD, Don't know why but the sound is great and everything.
on 02/18/2014 I got three of these headphones and refurbished under 20 dollars. they work great and were delivered on time. I love the sound and the cord is adjustable by length for different applications. for now I love them but I will rate it again if there's any issues.
Blown away by the comfort and sound of this relatively inexpensive set of headphones for my iPhone. I had the collapsible PX 200-II before but I ride a noisy train to work and needed to block out external noises. I love classical, reggae, classic rock and roll and trance music and these headphones delivered but the peak highs of violins and trance to the low thud and vibration of bass! Recommended for commuters who want a better sound experience at an affordable price!
they isolate noise pretty well, and they haven't been a burden on my head yet, and i do wear them for a good 1-2 hours at a time occasionally. Still afraid the cord will break, but it hasn't so I can't gripe on that yet. Mic quality is apparently good, at least when I skype or call, the other person preferred the mic to my computer's mic.
because I always liked to have a good sound thanksI like its shape and comfortneed not be recommended
Working really well, super cheap on the refurbished deal. Would definitely recommend to anyone looking for great headphones at a low price!
Well, so again, I trucked off to a retail store and bought these headphones. Obviously, I thought I was going to be blown away in that these models actually mentioned bass. I thought &#34;Wow!
Unpacking:I bought this headset from pinnacle, supposedly they are &#34;Sennheiser approved refurbished&#34;. It came in a plastic bag with a Sennheiser Logo, and looked brand new.
Unimpressive and somewhat disappointed. My son's Kunai Triton headphones that he uses for xbox are much better. My monster earbuds are better overall as well.Select another set.
Unfortunately, my confidence in the opinions of others was so high that I threw away the box. So I can not return them. But what will I do. Shelve them or give them away, because tomorrow, I will be shelling out the dough to replace my Beats.It just goes to show you. Don't believe the hype. No matter who it's coming from. Get out there and listen for yourself.
Answer: I am listening to these headphones right now on my Lenovo.The button however does nothing in the computer and my computer has a separate jack for Headphones and Mic so the mic isnt working the way it does with my phone.
