PuroSound Labs Juniorjams On-Ear Headphones Wireless Foldable Kids Earphones with Bluetooth, Volume Limiting, Lightweight and Noise Isolation For Smartphones/Pc/Tablet - Green

I bought these for the kids, based on reviews of the presumably larger version BT2200. The headband construction seems fairly solid with highly visible metal arms and hinges. The ear cups have metallic rings on the outside but the cups are just ordinary (and cheap looking) plastic. This is also true of the switches, up/down volume buttons etc. The volume buttons were stiff, didn't have good tactile feel and failed to respond literally 50% of the time. As an adult with a firm press I could usually force it to respond, but a young child would have difficulty. The ear pads are big and soft but didn't seem well-fitted to the device itself, they seemed slightly too big, loose and could easily be pulled off.A big deal is made of the volume limiting these provide, but personally I was surprised at how loud they go. Some anecdotal evidence #1 Put them down on the table with music at full 'limited' volume and you'll hear them across the room. #2 Stick them on my head at full volume and it was borderline tolerable, I just wanted to turn it down as soon as possible. Some less anecdotal evidence was shoving an iPhone running a db metrer app into the earcup at full volume and see what it said. Well, remarkably (to me at least) it seemed to average around 85db with the odd spike up to 93db. I find it hard to believe that young ears can listen to that volume for +2hrs. I also got the impression that these headphones were simply fixed at a lower-than-normal amplification i.e. reduced sensitivity rather than actively monitoring the signal and limiting accordingly. Based on this I felt there was no difference in outcomes between this volume limit function and just dialling down the volume limit on iphone (Settings > Music > Volume Limit) or enabling the 'EU Volume Limit' toggle. The perceived volume using the EU limit on some non-limiting headphones (Sony MDR-1000x) seemed about the same with the EU limit as these did without it. The sound quality was ok, nothing amazing and possibly lacked bass. I did notice that pushing the earcups into your head would make a crackle sound like the pressure created inside the earcup was deforming the plastic speaker diaphragm. One last point is that these headphones have a 'Daisy Chain' feature which allows two pairs to listen to the same source. What the website or product description fails to mention is that this requires a USB cable to be plugged between the two pairs. I didn't try it out but but most USB cables are fairly stiff AND short and this seemed like a bit of a cheap shot that and this feature should be described in a more transparent way.In short, *I* felt the volume was too high but definitely better than nothing but for £69 these has some rubbish buttons that didn't work reliably nor did they consider kids fingers. I sent them back.
