Marshall Major IV: This on-ear couple offers the characteristic Marshall sound, which is generally referred to as "warmer"-there is a gentle but wide bass increase with heights that are not overhauled. A small high-frequency hump gives consonants some details And avoids muddy male vocals, but overall the sound is smooth and pleasant. The upholstery is soft and comfortable, but the headband is tight, which means that this couple stays in place, but people with very large heads or humans Full hair may not be able to wear it for so long. A single multifunction button processes titles, volume and calls and is very easy to use and find without searching for. Or can connect another few headphones to the Major IV to enable the common use of a single audio device. Can be recharged, this is the first couple of headphones we tested with wireless Qi shop. It is a little cumbersome to place the ear cup properly on a loading pad without support, but it works - people who hate it, find a cable Enjoy this as a bonus function. However you choose to charge, the battery life of 80 hours means that you will not do it often.
