Razer Opus Active Noise Cancelling ANC Wireless Headphones: THX Audio Tuning - 25 Hr Battery - Bluetooth 4.2 & 3.5mm Jack Compatible - Auto Play/Auto Pause - Carrying Case Included - Midnight Blue

When i saw these i wanted to get them right away because they seemed to be the best deal that you can get if you wanted ANC, at least that's what i was after. After i bought them i charged them immediately which is sort of a flaw. Let me explain. It takes longer than desired to charge these things. The best time to charge them is overnight, but the tradeoff between charge time and play time is well worth the wait. I can spend most of my day heavily using this thing with ANC activated and it will last. Even after i am done using it i forget to charge it and when i use it the next day it still has like 50% battery life. Now onto the sound quality. The sound quality has some nice highs, but it leaves some desires for the lows. It still delivers the lows pretty well, but its not as rich as some others i've tested (ex. Skullcandy Crusher Wireless). Next is the main target for this device, ANC. The active noise cancelling to someone who hasnt really experienced it in depth before was amazing. I also heard from other people that it has a faint hiss when ANC is enabled, but it is really faint that your brain tunes it out after about 15 seconds. ANC delivers really well. For example, i played some music at around 50% volume and ANC on and i had my friend basically shout at me and i was only able to barely hear him. Last but not least comfort, another huge roll in wearing over ear headphones. Based on other razer products they have i had some worries about the comfort, but when i got them, they were actually really good. It doesnt clamp on your head, at least not hard so it has a nice feeling and my ears which are pretty much medium fit in the headphones and didnt touch the drivers as most people i heard from reviews have experienced. Overall, for the price the razer opus is honestly really great for the price and i would recommend buying it.

Unless there's a bunch of defective units being made (doubtful), I'm guessing all of the negative reviews are either fake, or they are connecting the headset via iOS / PC. I trust the rtings review site, which gave very high praise for the Opus, and it was not wrong. It did say their test setup involved using AptX, so I think that is the key to best performance of the Opus.The ANC is outstanding and lines up with the rtings detailed review. Also, the sound is very balanced and detailed in all levels, as expected. The bass is just ever-so-slightly low, which was expressed in the rtings review where low and mid bass was about -2 db below 'optimal'. However, I find at close to medium volume, its plenty loud and it opens up the bass a little more. To me, it's close to perfect and a steal at the price I paid, especially for the premium ANC. I've used the Opus while mowing on my tractor and I can barely even hear the tractor! I can listen at medium volume and it's plenty loud in this scenario, which prevents hearing loss.Very happy with this unit!

These are really nice headphones. I haven't played a huge array of music types yet but with both the vocal and piano / synth music tested so far the sound quality is very good. Not audiophile by any means but certainly good enough while working or most general purpose listening. They are a little bit tight but comfortable over all. Bluetooth and USB modes work fine, pairs easily with the former. Battery life is decent not great. Will last through the work day and into the next one before needing a recharge, basically.The noise cancelling is really impressive, almost overkill though. Depending on what's being cancelled the headphones can create an audible "white noise" if you have the volume turned down relatively low. But OTOH, literally loud washing machines, lawnmowers right outside the window? Not there. They're that good. Just need to turn the volume up a bit to not hear the white noise. The other thing I notice is a very slightly "pressure" build-up when this feature is on but this is probably a physics thing / not avoidable with phones that seal the area around your ear (more or less). None of that is a deal break though; definitely recommend these. Will update if any problems occur.

These are my earphones specifically for when I fly. They are very comfortable - I'm happy to wear them for 8 hours. I can sleep in them easily. And the battery lasts forever. The ANC works great on a plane and the sound quality is lush. Can't suggest enough.
