Am I the only one confused by Sennheiser's two new open-back headphone releases in the first half of 2025? The HD 505 and HD 550 continue the confusing naming of their HD 5xx line of headphones, and even more confusingly are tuned nearly the same... but sell for significantly different prices. So what's actually different between them? As it turns out... not a lot. But I found the differences.
