Massdrop products often offer better value for money. Eg HD6xx costs $220 but the identical product HD650 is ~$360. HD58x naming is misleading. In reality, it is one tier above hd599. Its within same class as HD600, HD650, HD660 but with different tuning.
The Sennheiser HD 650 and the Beyerdynamic DT 990 PRO are both very good open-back headphones for neutral listening. While the Beyerdynamic get more bass, they also sound a bit sharp and piercing. The Sennheiser have a smoother sound with less sharpness in the treble but lack bass. Compare Side-by-Side SEE OUR REVIEW.
Many gamers and streamers use open-back headphones like the Beyerdynamic DT 990 Pro. This is because open-back headphones prevent your ears from overheating and provide a more natural sound. That said, there are very few premium open-back headphones with a boom microphone for this niche.
Bundle Includes: Beyerdynamic DT-990 Pro Acoustically Open Headphones (250 Ohms) and Knox Gear Nylon Braided 3.5mm Male to Female Stereo Audio Extension Adapter Cable. Dynamic Headphone: The Beyerdynamic DT 990 PRO is an open dynamic headphone of exceptional quality suitable for the most demanding professional and audiophile applications.
I've been looking around on the internet and I have decided I want to go either with a Sennheiser 599 or a Beyerdynamic DT 990 Pro. The Beyerdynamic has a much better build quality, which I find important, but then again the Sennheisers have a detachable cable while the 990 does not.

I built acoustic panels (haven't hung them yet :)) following a tutorial on youtube. Total cost ~$30. I’ve been searching the local Marketplace listings for a couple months looking for a decent Yamaha receiver. Decided to go a little out of my budget. $500 for the pair.
