FAQS
Are these Qi-certified?
Yes,
While not designed with running in mind, this set fits pretty perfectly. It’s tight enough and light enough to go running. The soft foam makes them comfortable too. Also, they will allow you to hear ambient sounds such as cars which would be a good safety feature for runners.
Yes. Absolutely. Pair a connection to Major IVs and check your device settings (like a phone) to see what it’s reading. If it doesn’t show aptX, then consider whether the headphones are fakes. Fake Marshall headphones are selling out there in the global market.
If the headphones are worn properly, I don’t think leakage is an issue. I wear them on the train daily, they cut out a good chunk of subway noise at half volume, while being ambiantly loud enough. I don’t get looks or comments from anyone… Haven’t tested on a plane due to COVID, but don’t foresee it as an issue.
There is no cord, microphone is in the headphones, not sure where. Works very well, been used with no issues for work meetings for the last year and the microphone picks up everything
Probably not. They’re not over the ear, so you will hear a lot of external noise bleeding through. I ride the subway every morning, and can hear the background noise through the headphone
Yes
Yes
No. There is no mic on the cable and there is no remote on the cable.
It’s 2022… they go to 11.5!
These are on-ear headphones.
Yes if your computer has an old audio jack for plugging in external speakers. The headphones come with a cord to plug them in.
Some plastic and some metal they are well made
Yes, the Marshall Major IV’s will work with a Macbook via Bluetooth pairing. There’s also the option of connecting them through a headphone jack (cable is included).
They charge just fine on my Samsung wireless charger pad like a champ
It’s plastic covered in leather.
