Last week we reviewed the coloud boom which are an awesome set of headphones now its the turn of its companion the coloud knock .


These are quite nice and a reminder of the the old days when you had the spongy typed headphones and brings back some memories of the really bad headphones that where out in that era,one good thing they kept your ears warm,the rest was bad compared to todays standards of headphones .

The knock are a bit cheaper than the boom and as you know you get what you pay for but these are well worth the money and leave some competitors for dirt when it comes to sound comfort and style.

As mentioned you can see the old style spongy covers are actually very comfortable on your ears and will prove useful in the winter time too.

These would be more aimed at the younger kids in my opinion but then again everyone’s is different.

These are a  bit lighter than the booms which would be expected in the price bracket,there is no layer of comfort in the arches which the boom has.

Again the the zound lasso is present and its also got the mic and remote.

These can also adjust on both sides but not to the same extend as the boom can and the overhead band slots into the ear can remaining as one piece looks alot less appealing than the booms but bear in mind the cost.

The sound quality is quite good and better than i would think for the price bracket they are fit for not really any major distortion when your at max volume which was good so top marks for that .

Overall they are a cheaper build quality than the boom but they dont lack much in performance so its a win win.

These would be ideally suited to the younger teens or who ever of course decides what suits their own personal taste.

They are colorful,lightweight and cheap compared to other competitors and if you drop these they wont break.
