After purchasing and trying out many different earphones, ear buds and other headphone brands, there is nothing else that beats the Marshall Major IV! So far these are THE BEST-sounding headphones I have ever owned and I am confident I will not need to purchase another set for at least 10 years or more. All other brands and types were either too bassy, too trebly and/or not loud enough. In addition, most earbuds I have purchased over the years just kept on falling out of my ears and/or the cord would easily rip out of them! Overall these headphones have the best balance between treble and bass and sound even better with Dolby Atmos enabled on your Bluetooth device. For this review I used a Samsung Galaxy A8 - 2018 with Spotify for streaming and also the JetAudio+ app to play .M4A files of music ripped from my own collection of CD's. I personally recommend these headphones especially if you are a fan of loud heavy metal, Neue Deutsche Härte and other hard rock music as they also quash out most background noise without the need for Active Noise Cancellation. With all that said I certainly hope MDG keeps this product available as long as it keeps getting produced!
