Oriveti Twin Revive
Is it a lighter? Is it a multi-tool? A flashlight, fidget, emergency alarm or pepper spray? No, the device in my man purse is a DAC – the Oriveti Twin Revive, to be exact. We portable audiophiles sure have our share of audio dongles and...

iBasso D17 Atheris: Inconvenience for the Love of It
I thought DACs barely mattered. Then the D17 happened. Thanks to Hifi-Passion for loaning the iBasso D17 Atheris for a few days. Unfortunately my time with it was limited, so this isn’t a full review but rather a collection of listening impressions. German/EU readers can...

Sennheiser HD 650 in 2025
Lately, I noticed the availability and pricing of the Sennheiser HD 650 became unstable. Prices are on the rise and I heard a rumour about what could be the cause. So to add this classic headphone to my collection (again), I ordered one very recently...
