Depends if you are going to use them to your advantage in games, comfort is excellent, if you don't plan to take advantage in gaming and want them for just a regular headset to talk with no. For music there are better proper music headphone alternatives, though arctis 3 are decent too.
Arctis 3 has dolby, arctis 5 have dtsX, both are surround sound tech, but both are about equally as good, dtsX is more balanced, thus harder to figure out where the sound is coming from, but slightly more natural sounding, dolby, as usual, are cinematic-like and sharper, so you definitely hear where the sound is coming from.
The other difference is that the Arctis 5 is a christmas tree... I mean it has RGB... so if you want RGB and are willing to spend more money for Christmas lighting obviously the Arctis 5, otherwis go for the Arctis 3, since most movies are made for dolby surround and in games you will be able to distinct where the sound is coming from better, even if it's less natural.
For music turn of the surround sound(obviously) and if you don't listen to jazz, classical, blues and more complex metal/rock then you will have a good listening experience, while if you like to listen to multi-instrument instrumentals with many different sounds and notes and accents, there are very few(and expensive) gaming headsets that are both good for gaming and music and that's after you change cups, backplates and whatnot. Then I'd recommend you getting headphones for music, but it depends, I'm a little bit of an audiophile and I may be taking it too far...
Thank you man. Really appreciate it. I did some research, Steelseries are not giving product code now Arctis 3. So should I still go for it or should I buy HyperX Cloud Pro? As they are both going for the same price
The Arctis 3 have a slightly better mic, great software, and a bit more features, but apart from those they are equally as good. So it's your choice really, I wouldn't say that either of the advantages of the Arctis 3 are that much more important. Pick whichever you like more.
