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

Build 5 starsBluetooth 5 starsNoise cancellation 4 starAnd finally, sound 4-4.5 stars depending on connectionIt’s a great starting place, for the value, into quality headphones. The company is well established and has a good hold on both quality and Bluetooth technology so it’s too notch there.As far as the 4-4.5 stars go:Noise cancellation:it’s good but not the best, when confronted with noises that at can’t handle, it will crackle a lot. But those are only in very high noise situations.I have tried this on a flight and it works very well. I only wish they programmed a decibel meter or something in, to where the noise cancellation would not “try too hard”… but this is in high noise environments such as a vacuum cleaner in the same room, so it will be seldom that you encounter this, but a firmware update would be appreciated.Now, the main course; the sound:It’s well balanced and does not lean too low, too high, or too mid. I have a bias and love slight mid focused headphones. So this sounds a bit high for me, but I know that this is well balanced because it is slightly higher. I would rate a 4 star on the 3.5mm connection and a 4.5 on the Bluetooth… the wired connection seems to be slightly more mid focused, the wired is balanced and possibly even too high/mid focused for my taste (I have tinnitus so too high will make my ear ring).Some notes: it comes with cords and a case, which is up to Bose standards and competes with Bose in my opinion in everything but the noise cancellation. Battery life is good, but most headphones with active noise cancellation are not necessary that good in this area, so on par.The summary:Absolutely worth the value value if you are not looking for a bass heavy headphone. The noise canceling is sufficient for flights, the sound is pretty close to balanced, the build quality and Bluetooth is great. A good alternative to Bose… or even Sony if you want less bass heavy.

initial impressions are as follows:- good build quality, considering the weight and density- pairing is easy. i think it's lame that theres no multipoint connections, but it's not that bad. it's the digital equivalent of unplugging your headphones from one device and into another. i thought i would mind more, but its fine.- sound quality is pretty much what i expected: a flat, balanced, neutral sound signature. there is an appropriate amount of bass and it is punchy with a bit of thump, but is not muddled or overpowering. mid range is excellent. high end is pretty smooth overall. (just to be clear, and address some other negative reviews, THESE HEADPHONES ARE PLENTY LOUD, AND HAVE PLENTY OF BASS RESPONSE, but if you want brain-shaking bass, YOU WILL BE DISAPPOINTED.) They sound considerably better than the 7506s i was using before- controls are straightforward- ANC is pretty damn good, especially with lower frequencies.- i would have preferred a transparency mode, and i thought i was gonna hate the "press and hold" ambient button, but it's actually fine. it's like a pause button that pipes in external sounds. it works well and it works faster than i was expecting. totally not mad at it.- the fit is fantastic. it has ample padding in the headband and the earpads are, for lack of a better term, labial. SO. COMFORTABLE.- the app is the most disappointing thing about these, so far. not a whole lot of options. it begs the question "why did you even bother, Razer?" I would love to see this app upgraded to have customizable profiles and a real transparency mode.I use these in bluetooth mode on my phone and tablet, and in wired mode on my laptop. I plan to use these for casual music listening, tv/movies, non-competitive gaming, and audio/video editing. they seem like they will fit the bill nicely.UPDATE:after a few months and many more headphone purchases, these STILL have a spot at my desk. I now own technically better headphones (HD 560s and a couple of T50 mods) but i still reach for these when i wanna go wireless or i want to passively or actively drown out my surroundings.

Great anc headphones.Sound-Good but pretty standard I would say. Very clear sound but, not very bass heavy if that’s something you are into.Build Quality-Nice build quality would have preferred a little more aluminum in the build but they are still nice feeling, nice looking, an a mature looking headset from Razer. Comes with nice faux leather carrying case that holds all the accessories included with the set.Noise cancellation-My first pair of anc headphones. Yes it works. Bought these for a noisy classroom setting an it blocks out the noise.Comfort-Very comfortable to wear. I wear glasses an they haven’t put any pressure in those areas where some headsets can wear you out. Lightweight an good leatherette padding on earcups an headband.Overall-I would recommend these to a friend ifthey are on sale ( I got them at 143.00 usually runs around 199.00 for this set)You are someone looking for anc headphonesIf you are a Razer fan an you like having products from their ecosystem.Wouldn’t recommend if-You lust for bass in your headphonesYou are just looking for a wireless headphones an anc isn’t a priority.
