They sound Incredible!

Funcionan perfectamente y la batería es inigualable

Super comfortable and well made. Not great for noise cancellation but otherwise amazing

Compré estos cascos hace más de 3 meses. Me llegaron con un 80% de batería y ayer los cargué por primera vez usándolos cada día sin falta durante 2h. La duración de la batería es insuperable. Yo los uso únicamente en el gym y van genial ya que se ajustan lo suficiente para que no salten pero sin llegar a ser molestos. Además tienen una calidad de sonido increíble. Totalmente recomendables

Showing my kids this movie so they can understand where my quotes come from. Great movie!

Omg, this Marshall Major IV On-Ear Bluetooth Headphone sounds SOOOOO good. My jaws were literally dropped after I paired this headphone up with my phone, and the first song "Hotel California" (Eagles, Live) played out the earpiece. I closed my eyes and this headphone brought me to the live concert hall. I then continued to play thru a bunch of audiophile soundtracks to give this pair of headphone a worthy test-drive.The acoustic performance of this headphone is truly phenomenal (concluded after a few hours of listening now). The bass is tight and accurate, probably benefited from the 40mm driver element inside this headphone, the volume of air it can move is not anything that an earbud can compare. The midrange is smooth, yet texturized, layered with fantastic details. The treble is clean, clear and silky. It is really a pleasant surprise to hear such studio quality of music reproduction in this headphone from Marshall. The microphone on this headphone is also very good, I asked about my voice input in a few teleconferences, and the responses are positive.This headphone is indeed comfortable. The ear cushions are very soft, and the size adjustment is massive (seldom do I find a headphone that will fit my 8years old as well as it fits me). I was a bit skeptical first, as this is an "on the ear" headphone, I was worry that it would not be too comfortable; but now I have to say that, to a certain extend, this one is more comfortable than the "over the ear" type as it enables more air-flow, it is "cooler" and less "hot/warm".I also love the single "multi-directional control knob", on/off, pairing, volume, track control etc. all intuitively managed by this single knob, brilliant design!Last, but not least, charging this headphone is as simple as putting it on a Qi wireless charging pad. Or hook up an USB-C cable. One full charge is supposed to last 80hours.2 minor things that I wished Marshall included with this amazing headphones:- a carrying case- a wireless charging padThen this would have been a PERFECT product.Please note that there is no noise cancellation capability on this headphone. It is not priced as such neither. And for the cost of this headphone, I really don't think you can find another better performing set.Thank you for reading this review, I hoped that this review & the pictures are helpful to you in support of your purchase decision.
