Review on 🎧 Auris Amplify Portable Hi-Fi Bluetooth Adapter Receiver with 32bit DAC Amp, LDAC, aptX HD, aptX, AAC, Clip & 3.5mm AUX Output - Black by Ray Gist

It didn't work on the Sennheiser HD600, on the Grado SR60 the bass is muddy. The Sennheiser is difficult to control and usually requires a different amp; Grado is easy to manage and control from your phone. I compared it to EarStudio ES100. The Auris sound is low key, muddy and overall limited. With the ES100, everything on the Sennheiser is good except for the bass; Grado is amazing on Grado. If you have another device and have the patience to put a lot of things together, you can get good sound by running it through an external headphone amp. From an ergonomic point of view, the device is not bad, but the clip is insufficient.
