Hi! I made a thread on here a few months ago, but now I'm ready to make a purchase in early June/ End of may. I was wondering if anyone could guide me to a purchase. I've been doing some research and I think I'd be interested in either the Beyer dynamic dt 770 pros or the Audio Technica ATH MSR7GM. https://www.amazon.ca/dp/B008POFOHM...olid=278OIVIRS8QNG&coliid=I3F5WELY49BUZ0&th=1 https://www.amazon.ca/dp/B00PEUBIKM...TF8&colid=278OIVIRS8QNG&coliid=I3LATYCY69C4EH I'm looking for something closed back (I have Sennheiser HD 558s already), with good mids/highs but also present bass. I listen to all genres of music so It's hard to make a recommendation on that I think. My budget is supposed to be under $300 Canadian, but I'd be willing to go up to the Audio Technicas if I need to. I'll be using these headphones with me basically everywhere, but especially on my phone and on my computer. On a bus, maybe while exercising, etc. etc. My biggest issue that's stopping me from buying the Beyer dynamics is the fact that it doesn't have a removable cord, and the biggest thing stopping me from the Technicas is the price. I'm antsy about the cord because my HD 558s had a bad cord that i had to replace, and I want to be able to have the option to do so in the future in case something goes wrong. Can someone help me out?
