Customer Testimonial

"Wow. These are absolutely phenomenal headphones. I bought them about a year and a half ago and I use them all the time. I had a pair of on ear headphones from a no-name brand a few years ago and, while they served their purpose, they were not impressively loud and became a little aggravating on the ears after a while. These sit very comfortably on my head while I do chores around the house or yard work etc. I run a mobile auto detailing business in my spare time and use them for that as well. I don’t have a particularly large head and they fit nicely, but I imagine they would be better for someone with a big noggin. If I find myself looking down for too long they will start to slip off my head. I wouldn’t even attempt to do any kind of cardio with these. Weightlifting, sure but running - no. They are too lose and when using the noise canceling feature, any excess movement makes it crackle.

The noise canceling is pretty decent. It’s 100% better than Bose quality and it’s plenty powerful to muffle a mower, vacuum or grinder. It almost entirely mutes plane noise. Like I mentioned, it doesn’t take much jostling to make it crackle, but if it becomes too annoying I just turn the NC off.

Sound quality is also very good. Depending on the app/song I’m listening to, it can get EXTREMELY loud. So much so that I have to turn it down - which is saying something because I listen to my music on full blast most of the time. Sound quality is much better with the NC on, but marginally louder with NC off.

Build construction is solid. Feels like many steps up from just cheap plastic. Pads are very soft and so far the body has been durable. I’ve dropped these on the ground a few times and, while they are covered in scratches, they are still performing fabulously.

Finally, and very importantly, the battery life on these is UNPRECEDENTED. I mean I will use these for hours a day for like 2 weeks in a row before even thinking about charging them. I think they advertise 16 hours, but no joke I have probably used these for 40+ hours between charges and they still weren’t dead. Unbelievable. There is also a widget for the iPhone but I’ve found it to be entirely inaccurate.

Bluetooth connection is lightning fast and has superb distance. In an open field I’ve used them further than 80’ from my phone.

The hinges of the earpieces have become a little squeaky after 3 years of ownership. Overall, this is a minor gripe that I actually had to think about to put in here.

Overall these are a fantastic set of headphones and have earned their 5-stars from me. I bought another product from Modern and had to get in touch with their customer support and was very pleased. I will buy from MA in the future

Edit: 10-11-18

I am still using these headphones and continue to be blown away by their deceptively good quality. I mean these suckers refuse to die. The battery life remains miraculous. Still getting 30+ hours of play time on full volume. That is an absolute feat considering the common life of Li-Ion batteries. The buttons still work. The Noise Cancelling still works. They remain unconventionally comfortable. In my previous post I mentioned that they had started to squeak around the hinges. Yeah that just stopped. I am seriously astounded by these headphones and wonder if I’ll ever even need to upgrade to the XD500’s. In any case - Modern Almanac has still got my vote when it comes down to a reasonably priced headphone of extraordinary longevity."
