Sennheiser HD 6XX Open-Back Headphones US$170 + US$20 Delivery (~A$289 Delivered) @ Drop
Drop x Sennheiser HD 6XX (HD 650 variant) for US$170 + US$20 shipping to Australia. Total was US$190, which came to about A$289 for me via PayPal’s rate today.
Historically these sit around US$199–220 and only occasionally drop into the high US$160s–170s, so this is about as low as they get direct from Drop. Previous OzB deals have typically worked out to roughly A$280–310 delivered depending on USD and exchange at the time.
Key points:
Same drivers/tuning as the HD 650, just the Drop-branded, dark blue version.
Open-back, 300 Ω – you’ll want a half-decent amp to get the best out of them.
Ships from the US; Drop quotes around 2–4 weeks delivery time to Australia once dispatched.
Price based on delivery to QLD and my PayPal conversion; your AUD total may vary slightly with exchange rate/fees.
For anyone who wants a deep dive on the Sennheiser HD 600‑series (including HD 600/650/6XX, 660S2, 490 Pro, 620S), this video gives a great technical comparison and tier

Keep in mind that sound is highly subjective, so treat it as one reviewer’s take rather than objective fact.
