That’s the hard part about this, you will get conflicting points of view and opinions no matter where you look in this hobby. However, definitely be careful of those over hyping up products or shilling. We all have our own preferences in sound, for example my preference is towards bright or V shaped headphones so I am not the biggest fan of Sennheiser, therefore you won’t see me heavily talk up the brand.
I mean, there is a select few gaming headsets that are deemed worthy of purchase for a gamer. around 95% of the headsets are trash or cut so many corners it’s not worth the price tag. Once you hit above … I want to say around $150 USD and up your better off going to an actual headphone setup.
This is a big step forward and the start of a journey so to speak, we can’t necessarily pick the headphone out for you as we don’t know your tastes in sound in particular, we can only recommend options to you and try our best to explain it. If at all possible find a way to try out different sound signatures. It’s a good idea to try and narrow down what your preference is. preferences in build quality, sound signature, sound stage, detail retrieval, comfort / pad style, budget, etc all are quite different and vary drastically. You also have headphones that can be driven ampless just fine.
Depends on what you go with. Sennheiser generally keeps their sound signature around the same area of neutrality with smaller changes, outside of being cleaner or more detailed of sorts and in other cases a bit more impactful and bassier. They are just known for great neutral or “reference” grade headphones and are really fantastic for those who love vocals in music. Beyerdynamic and Hifiman are for those who like the higher sounds of the music such as cymbal crashes, orchestra, classical, etc at the same time they are some of the better choices for your competitive gaming due to the brighter signature. Other brands fit other areas quite nicely. Just all depends on what your looking for in particular. If at all possible, if theres a return policy, I don’t see the harm of auditioning one of the Sennheiser 6-- series see what you think, if you feel it’s worth to you.
