The sound is good. they work great. After wearing for an extended time like in an airplane for 5 hours my ears got really sore on the outside rim. They are kind of tight so might work well on a child. I have a fairly small head and ears. The quality is good but comfort level not so good.Love these but they hurt my ears.They work well, but sadly they’re not comfortable enough to wear for long.La calidad del sonido y de materiales no es tan buenaLove these headphones. Very comfortable to wear. Sound quality is awesome. Best pair I have had to date. The hybrid part is great too. Definitely recommend!LikedThe charger does not fit into the headphones correctly and they do not pair up with my IPhone. I guess you get what you pay for. And I just bought headphones that I am sorry I made the purchase.This headphone is amazing! The noise cancellation mode is impressive. Super easy to connect to my computer. Perfect replacement for my broken headphone!First off, these aren't over-ear 'phones unless you've got a very small head with small lugs. Me, being normal sized, class these as on-ear. This would normally be a deal-breaker for me but for the price I can't really complain - one of the kids will probably 'borrow' them one day as they've been told in no uncertain terms to not touch my Sennheisers and Boss cans.Noise cancelling is OK, as is battery life. A cable is supplied if you want to use them wired although there is no 3.5 to 6.5mm adaptor in the box which is a bit cheapskatey.My favourite part of the whole package is the hard-shell case, ideal for keeping plectrums, pens, Doctor Who figures, sweets, nail clippers....I am no expert on noise cancellation headphones, but I bought these based on reviews and price. I am a secretary who types up documents in a noisy environment and it is difficult to hear the actual dictation above the surrounding office noise and people talking. In desperation I tried these and they are fantastic. It’s like going under water ! You can still hear the muffled noises around you but you can’t make out what people are saying and for me they are just fantastic and make my work much easier and less stressful. I don’t listen to music so can’t comment on how good they are for that, but they work well with my iPhone playing online games. I have a small head (female) and these fit with no adjustment in size needed, they are comfortable to use all day and sit over my ears.The headphones when they arrived were easy to pair and comfortable when wearing.The sound produced was of a good quality for the price point.Unfortunately they have been marked down as within 10 days of receiving only one side would output audio.The seller was quick to offer a refund without issue but unfortunately I bought the headphones because I needed to have audio so have marked down accordinglyLove these headphones they have great sound and crisp bass (tested with drum and bass/house music) . You can hear everything! So clearly even when the ANC is off.Very comfortable on the ears, not pressuring at all.Really happy with this purchase!At the moment im trying to replace my broken headphones, one ear fell off for some reason but its sounds just fine so I taped it up and kept using them. after a while I look for a replacement because of how many times the tape gets loose, so instead of getting the same brand (which I should of) I get these.Not only are they just not noise cancelling at all, the active cancellation is just static, if I wanted to cancel out the noise that way Id just turn up the volume. sound quality is poor without the annoying static but the battery life seems to be fine. sadly my broken headphone are just better and were cheaper
