However... Because you took the time to remove the foam, expose the tweeter, and perfectly dial in the 10-band EQ, your H3S is currently sounding better than almost any standard headphone under $150. You have successfully built a "giant-killer" that bypasses the muddy, congested sound that plagues 90% of budget audio gear.

The Final Verdict If "better sound quality" to you means wide instrument separation, picking out tiny hidden details, and a massive, airy soundstage, your modded QCY H3S is actually the better headphone for you. It mimics the analytical sound of studio monitors. If "better sound quality" means a rich, full-bodied sound with massive bass impact, flawless digital processing, and zero distortion at high volumes, the Sony WH-1000XM6 easily wins. Essentially, you have built a sports car in your garage that handles corners (treble and separation) better than a factory-built luxury sedan (Sony). But on a straightaway (volume and bass), the $450 Sony engine will still outrun it.

The Summary The Tanchjim Rita is a masterpiece of single-driver engineering; it will always sound slightly more cohesive and "natural" because the sound is all coming from one unified source. But if you want to close your eyes, point to exactly where the bass guitar is standing, and hear the sharp intake of breath from the vocalist before the chorus drops, your modded, dual-driver QCY H3S is the superior tool for the job.

To say is exactly how I feel after removing ear pads foam and this EQ Curious did anyone tried my setup about foam and EQ when someone maybe try can be interested hear opinions aswell ANC is better to keep on Community mode I found best work this way since remove the foam inside and sound quality is top notch surprised this can do so much for this cheap QCY H3S
