   GREAT PRODUCT BUY WITHOUT SECOND THOUGHT
   Cosmic Byte Immortal Headphones offer excellent value for money. They combine high-quality sound, long battery life, and a comfortable design.In terms of audio performance, the Cosmic Byte Immortal excels. The 2.4GHz wireless connection offers low-latency audio transmission, ideal for gaming and real-time communication. The Bluetooth functionality adds convenience for casual listening on the go, while the wired option ensures compatibility with devices that lack Bluetooth support. The sound quality is clear and balanced, with good bass response and crisp highs.

   Cheap quality
   Not that good speakers and not that comfortable. Bring back Equinox Polaris or other older ones. At same price they were wired but way more comfortable and ergonomic and better sound quality. I had one of them for 2-3 years and I had no complaints.They refused to repair my one side speaker and they don’t sell those anymore and I had to settle for this.They put so many different connectivity features here that basic things are neglected. Apart from comfort and sound quality, even the volume button doesn’t interact with PC/smartphone volume anymore. It’s just increasing and decreasing the headphone volume which comes in cheap headphones under 1500. Now I have to set headphone volume and device volume separately just like I used to do 10 years ago. RGB has only on/off option. Can’t even select one particular color. The Mic doesn’t have any indicator to let me know if it’s muted or not. I’d say it’s a major downgrade in all angles except for connectivity.Apart from all above, the controls for play/pause, mode, next/prev all are confusing and I have to think 5 secs before clicking.Edit After using it for 7 days: I noticed the battery doesn’t even last that long. It says it should last for 40 hours. May be that’s with RGB off, there’s nothing mentioned anywhere. Assuming that, with RGB on, I expect it to last for atleast 20 – 25 hours. But it lasted only for average 10 hours or less. I use it for 2 – 4 hours everyday. I thought it should go 10+ days easily. But I charged twice in a week. Every 2 – 3 days it needs charging. There’s no indicator or anything so that I can know how much battery it has left. I bought it for my PC, I connected with 2.4GHz. There’s no app or anything that tells me about the battery. Only if I connect with bluetooth I’ll get to know. I don’t want to do that much hassle. I just want to play my games peacefully without listening a voice saying low battery in the middle of an awesome fight.That volume wheel doesn’t have any friction or clickiness. It just rolls like a wheel without any resistance. Because of that and the position they’ve given it it often rolls by mistake while putting on. Then I’m like why is the volume so low, I increase the PC volume and sound is still really low before I realise it’s the headphones.And when I use it for like 2 hours or more my ears are starting to pain. The cups are not comfortable at all.This is the worst product Cosmic Byte created and I’m changing the rating to 1 star from 3. The problem is just because they want to sell this, they stopped producing their other great models from equinox series and even stopped reparing them. So that we’ll be forced to buy this.And I don’t have any other options where I get a good headphone that’s comfortable and has RGB that goes with my awesome Desktop.Anyways thanks to Amazon, I’ll be replacing this once to check the battery issue. If it’s the same then I’ll be returning this. I’m glad I was skeptical about this product, so instead of buying from cosmic byte directly which I usually did for my previous headphone, mouse or keyboard(Which were great by the way), I bought from Amazon with 400 extra so that I can return easily without any hassle.Edit: The replacement has the exact same battery and same issues. So I think all of them are same. The model itself is bad. Anyways, Thanks to Amazon, I got full refund. That’s why I do not buy from company websites, even if they cost less, because you won’t get refund when you don’t want the bad product.

   Writing review after using it for around 2-3 months
   Sound was not loud but build quality is good and fitting is also not appropriate.Good for gaming but not ideal for music. The volume control function works properly.

   Performance and comfortability
   Absolutely amazing headphones! The cushions are super soft and comfortable even for long use. Sound, mic, and calling quality are excellent with perfect noise cancellation. Easy to connect via Bluetooth, wire, or driver. The RGB lights look really cool, and the battery backup is outstanding. Great choice for music lovers — I mostly use it wired, and it’s super comfortable. Totally worth it! 🎧🔥

   Not for Gaming (ignore at all cost)
   1. Bass: Good2. Treble: Bad3. External mic: Good4. Internal mic: Bad (Doesn’t work during calls (while connected to phone via BT or AUX, dont know about dongle because connecting type-A dongle to smartphone is weird))5. Durability: Avg6. RGB: Good7. Body flex: HighPROS:1.Good bass,2.Good rgb,3.Fabric earcuffs (no problem with long term use),4.Triple connectivity options (works fine),5.Battery backup (good backup),6. External mic quality is goodCONS:1.Not for gaming (ignore at all cost),2.Footsteps are not clear (due to heavy bass in music mode, gaming mode is kinda uselesss even though it reduces bass but doesn’t amplify treble),3.Gaming with AUX cable is a bad idea too because of too much bass (mode cannot be changed when connected to AUX),4.Headphone is not collapsable or foldable (hard to carry while travelling),5.Triple click sometimes register as double click at mode button, which causes it to switch connectivity mode (BT and Dongle) instead of changing music mode to game mode.6.Mute mic slider doesn’t work sometimes,7.Doesn’t support low capacity chargers like 10W chargers8.Weight is on the higher side9.Headphone is quite big so it might not fit some people’s head (loose fit)

   Good product, very useful
   They are amazing for their price point with amazing battery life.The headset sports a sleek black design with a modern and professional appearance. The build quality feels solid, with a combination of metal and plastic that provides durability without feeling overly heavy.The sound is very nice and fits my head and ears. The adjustable headband and cushioned earcups ensure a comfortable fit, making it suitable for long gaming sessions or extended listening periods.

   Price high for decent product
   Giving my review in 2 days reviews, i bought it for professional use like to online class and mostly for song, because i big song enthusiast, So sound quality is bad litterly there is little sensation of bass and that’s it no premium feel, i used to use Wings phantom which was around 900 rupess that was great comparing to this but this headphone doesn’t have good crisp of sound like treble bass clearity many aspects in it. they are charging 2600 for this quality is pathetic. So my advise is if u want bluetooth + dongle + aux and basic sound quality mic is good not great u can take it .. overall decent quality and note u will full sweat in ears if like use it for 2 to 3 hrs
