For Gaming: When playing battlefield 4, I could hear my enemies approaching from either my left or right side, which ultimately, was pretty darn cool. Stereo effects with THX quality really makes your triple A effects amazing, soundtracks and small sounds superb, and honestly, I wouldn't doubt that this will be a great experience overall.Noise Cancellation: I think it's great, as long as they fit your head just right. Also, depends if you are counting if you are listening to something or not. If you are, yes, it's going to be hard (harder than usual, at least) to hear anyone speak to you, but not entirely. If nothing is playing, yes, you can faintly hear someone. I'm not expert in these matters, but I feel its pretty good, considering.Sound Quality: Superb. I think it's amazing, personally. While playing battlefield in stereo, I can literally hear people approaching from my left and right, and this itself can help you become a better gamer. This is superb for solo watching horror movies, or triple A movies themselves. Rumble effect has a added effect to the audio experience; just depends on your discretion.Overall: Price wise, it's super expensive, and you might need "Razor Insurance/Amazon Insurance" for incase of customer loss of items. (wireless USB plug in, damages that may occur, etc.) I purchased renewed and saved 50-80 dollars. I've had my headset for almost two months now, and it's not had any kind of issues.The battery is debatably issue; if you use the rumble effect with certain intensity, yes, this will tear down your battery quicker and will not last it's potential life span of 8+ hours. If you turn off the rumble effect, and just use sound quality, than yes, it's going to last a lot longer."Cool" ear muffs: Yes, these do work as intended. I have had my headset on for 8+ hours and never had sweat around my ears. This feature is really nice, because over long term use, that sweat and junk can really make a headset gross and unsightly. Not to mention, the absorption of sweat in the material, which gives a even worse unsightly scent/aroma. Personally, if the sound quality doesnt get you, the rumble effect, the noise cancelling feature, than you're going to really enjoy not sweating into your headset.Tip: I don't know how the cool ear muffs work in a hot/warm room, and I cannot say for certain if they will work at their best in these conditions. Just keep that in mind if you have a warm room.Tip: Remember to plug in and keep charged after long use, or for a few hours of play. You might kick yourself in the butt without hindsight.Tip: If you are famous for losing parts like dongles and the USB's provided for wireless set up, be sure to go to razor and buy insurance for "customer induced loss/damages", otherwise you're going to have a hard time trying to find replacements, if, any, at all.Tip: When using the Haptic Intensity while charging, this will allow for an annoying "plugged in/plugged out" sound of your headset on the PC. I can't say I know what will happen when it's a PS4.Tip: When buying renewed, remember that these have been previously used/repaired and sold back to you as new as possible. My first order was okay, but than the battery started having charging issues. My second pair worked fine, though.NOT BLUETOOTH COMPATIBLE WITH HEADPHONES OR SWITCH!I’ve always heard of Razer headphones and had been eyes the Nari for months. Finally scraped together the money and while they were good, they just weren’t for me. I wanted versatile headphones but these are best ONLY FOR GAMING. If you want headphones that are Bluetooth with your phone and other devices, get the Razer Kaira Pro. A bit more but worth it.So far, the only issue I've had with this specific headset is that it gives feedback into the mic from the game while in an xbox live party on pc. It could also just be the app itself on pc not functioning properly. Will have to dig into it and will update review once I find out. Other than that, sound quality is relatively crips, the haptic function is amazing.Took me some time to get used to the haptic feedback (bass) – it’s like having a subwoofer strapped to your head (in a good way), but WOW are these amazing.PROs:- Excellent sound for gaming.- Excellent sound for movies.- Excellent battery life (20 hours).- Perfect fit (auto-adjust).- Absolutely ZERO lag (2.4 GHz dongle).- Great (but not top-notch) sound for music (see more below).- Quick and easy setup, software install, BIOS flash, and APP.- Loud with ZERO distortion. (Not sure why the top negative reviewer would even give this product 1 star if he received a defective set – get a replacement set and do a real review. It’s like trying to test-drive a car you’re about to buy, with flat tires. No need.)CONs:- A bit on the heavy side compared to a wired gaming set I have. Obviously because of the batteries (thus, the excellent wireless battery life – does that cancel itself out?). Very comfortable, I got used to the weight. Minor gripe. Now, my wired headphones feel way too light.- The APP settings for haptic feedback have “too large” gaps – from 0 (no movement at all), the next step is 20, 30, +10 each, to 100. I would like to set it to 5. Again minor gripe, as I can lower the volume and reduce the haptic feedback (also, mounted softer pads, see below).- Analog dials for volume and mic / voice – adjusting them on my head, it’s easy to accidentally touch the volume control and drastically change the volume. Should have UP and DOWN buttons for digital adjustment. As I’ve had them less than a week, I’m starting to learn to grab them in a different way, preventing accidental touches. Still, a digital +/- button set-up would help (there are digital power and mute buttons, why stop there?). Something to consider in a new model.- No wireless charging via a desk stand. Really, more of a future upgrade to “Nari Ultimate 2?” – using a USB cord to charge is a bit of a pain. I love wireless charging. No true wireless gaming headset has this feature (as of this writing). Something to consider in a new model.As you can tell, the PROs outweigh the CONs in a huge way. Suffice it to say, the CONs are more of a nitpicky-nature than real CONs, rather, small annoyances, more of a wish-list. As for the “great” but not “excellent” sound for music (tested on 320Kbps MP3, a real audio CD (44KHz) and a real audio DVD (48KHz) – they just don’t compare to my RIDICULOUSLY amazing-sounding Sennheiser 800S wired pass-through, over the ear set. Rightfully so, that set is $1700. And the Nari Ultimate is a wireless GAMING head set.I purchased two XL oversized replacement pad sets, a micro-suede and a velour-covered set. Both of them reduce the level of haptic feedback (are 30mm thick) and feel softer than the almost-perfect original pads.Absolutely recommended. Reconditioned, LIKE NEW. The only difference is a generic box. Everything is rock-solid, with big savings. Wonderful tech-support as well, had to call the seller as I couldn’t find the USB dongle, not knowing, it’s so tiny, it’s stored in one of the headphones. Great purchase.Pros: rgb, wireless, haptics are cool when they're not awful.Cons: battery life is truly awful, sound is even worse. Mic is bad. Wireless range with 2.4g is atrocious. Expensive. Software is bad.What can I say? I bought a refurb unit for about half the list price. They're giant, heavy, and look cool. The haptics are a neat gimmick, but don't add anything to the experience once you're used to them.The EQ settings are just terrible. Google these headphones and check out all the discussion about people trying to find decent settings.Tgese sound like crap.The mic is bad enough that my gaming buddies have commented on it without me asking.Battery life is about 4 hours. If you don't plug them in after every single use, you're not going to be able to use them next time you sit down.Wireless range is about 15 feet. I have these hooked up in my living room, and they don't even reach to the kitchen (within line of sight, maybe 12 steps).I came from a set of Arctis 7's, which have amazing sound, amazing mic, and I can go out to the garage without wireless getting weird. They also have a 25+ hour battery life and are deadly comfortable.Dont buy these, buy Arctis 7 headphones instead, they're better in literally every possible way, minus RGB.I was sent a pair of razer kraken ultimates instead of the Nari ultimates. Absolutely careless seller. I wouldn’t be too mad if it was even a pair of Nari or Nari essentials, but they are Krakens, the whole purpose of buying Naris is for the wireless and spatial audio and hyper sense. But all the krakens have are LEDs and THX. Just disappointed in how careless the seller is, and essentially false advertisingheadset is great. really love it.. however the mic quality is ass. like i bought it at the dollar tree.. so keep that in mind.Said this would work, does not at all. Did not work on PC. WRONG PACKAGE AND ITEM WAS SENT TWICE. RETURNED BOTH. Not happy.sound is really good. connectivity and battery life could be better.
