Sennheiser hd660s2 The problem I'm having

Hi there, I have IE 600 and HD 660S, and many other IEMs, and I also do music professionally. What you're describing can have multiple reasons, and I’d suggest just ignoring it. If you're unsure, you can always order another pair of HD 660S2 to compare, then send one unit back. First reason is that

Headphone brand Sennheiser is up for sale

Honestly not entirely surprised - Sonova always felt like an awkward parent for a consumer headphone brand. Their DNA is medical hearing aids, and Sennheiser's strength is in the exact opposite direction: audiophile listening, studio monitoring, the HD 800 series crowd. The bigger question for me is

Which Sennheiser tuning do you prefer?

Hello, I've been using my HD 580s for many, many years. They're headphones that make me happy with practically all genres of music. Wonderfully silky vocals, a brilliant piano attack, sparkling piano playing, the sustain of the strings… A real Sennheiser joy. I recently bought the HD 660s2. I wanted

Should we buy headphones after Sonova’s news, or wait?

No, I don’t think Sennheiser is going out of business. Sonova previously tried to make headphones work (I had a pair of their Phonak brand IEMs), and they wanted to get into the headphone business again with Sennheiser, and… I don’t know why, but I guess they decided not to do headphones, again. And

Why do people give Sennheiser such good rep when - in my experience - their top headphones have build quality issues, specifically CREAKs. E.g. HD 490 pro

Yeah tbh, i love the sennheiser hd 500 sound but the amount of hate i have for the fanboys and the company just delivering plastic creaks is annoying. I did have the hd 660s2, only briefly, they only creaked when i made them, as in, when i held them in my hands and rotated the cups - otherwise they

HD 620S vs HD 599 opinion

I think you have the same "issue" as me. Most people dismiss warm sounding headphones are wrong it seems and prefer the neutral audio. I, personally love the hd 598, 599, 660s2 sound, which is WARM sounding headphones. I also tried the hd620s - they're not bad but they aren't warm sounding, they can
