Great product. Excellent value for money. You won't be disappointed with these. But, and this is important, these are a great set of headphones HOWEVER they are not in the same class as headphones costing over £100/each. If you appreciate that, then you'll be happy. Rock on...

After many years of buying $15 headphones I decided to splurge and buy something I hoped would last more than a year. My only requirements were detachable cord (tired of one ear failures) and over the ear design.I bought a used M40x from Amazon Warehouse Deals. (Used - Acceptable - Cosmetic imperfection(s) bigger than 1" on interior of item. Item will come in original packaging.). I paid $57. Don't know if I got a different pair but these were perfect except for dirt/dust. Used for an hour and seem to be great so far but I'll continue checking them until return window closes. (for those wondering about used/Black Friday returns)I have never been a big audiophile. I do all of my music listening on a laptop. Currently a stock Dell G3. Quality has never been an issue for me...until now atleast. I should add that I'm a 20+ year union Stagehand. Over the years I have become so numb to music that I can sleep backstage during sets at a rock festival. I can tune out anything.First impression of the M40x's was amazement. I only listened for an hour or so but the difference between these and the throwaway headphones is night and day. They sound very clear even on my laptop. I can only imagine the performance I would get on a good sound system.The Early November - The Acoustic EP was mind blowing. Al Bairre - Right Here in July is breathtaking.Adele, John Anderson, Alan Jackson, Sam Smith, Regina Spektor, Jeff Buckley. All sound like new music again.Took a star for the wild twisting of the cups. I can easily see them breaking soon from the stress of flopping. Still I'll buy a 2nd pair for gaming when they go back to $75.Highly recommended for amateurs like me. Gaming is going to be awesome.

Noise cancellation is so good on these headphones. Really like these over first generation

All over its a great pair of headphones. Volume control, noise cancellation. . Great quality!!!

Wonderful and very satisfied. Does exactly as they say and definitely an improvement over headphones with wires!

I’ve had this for 3 months now, I waited to do a review to make sure it continued to work. Overall, I’ve been very happy with this product. I question the accuracy of the sleep monitoring but it seems pretty close. I run/walk a lot so I like all of the stats it includes. I did have about a month where the running stats didn’t work. It would tell me overall time and distance but nothing else. I waited a couple weeks and they just magically started again so not sure what happened. Battery life is good but I turned my screen sensor off. With that off, I can get the battery to work up to 2.5-3 weeks without a charge. The only notifications that come through are calls for me so if you’re trying this for notifications/phone connectivity I wouldn’t recommend.

Ive been using these headphones for over 2 years and they are great for only around 25 dollars.

My first impression is that these are nice headphones and im excited to see how they do over time
