Review: Very dissapointing. - Let me kick this review off with a very clear message. THIS IS NOT A DAC/AMP COMBO LIKE ADVERTISED!!!! Ok now that that's out of the way. Where do I begin. The software that comes along with EPOS is awful, like most of sennheisers software, it has a lot of bugs, the presets never save the microphone options so I constantly have to turn off side tone and change from warm mode to off. Which is incredibly annoying. The sound quality was, marginely different at best. It was a little increase I will admit, but for my headset the PC38x, it was practically useless. It is a very clean unit and is very sleek, so aesthetic wise it is incredibly pleasing. But other than that I wouldn't touch this unless you truly wanted a DAC. But do not fall into the trap that I did in thinking that this is a DAC/AMP.
Review: Shocking do not buy - I purchased and it broke within a year died had it replaced and the replacement had the same issue of not turning on with 3months

### ⭐ Shocking do not buy
*by D***R on 20 April 2023*

I purchased and it broke within a year died had it replaced and the replacement had the same issue of not turning on with 3months

### ⭐⭐ Bargain Price but Faulty
*by W***E on 29 April 2022*

Was perfect for the price and delivered a little extra juice to my headphones. Sadly the amp sometimes would cut out the sound without warning and other times would shut down after a few days of use. What is more, I paired it up with the same brand's headsets, GSP 600, only for those to be faulty on one side as well. Sadly I will be returning both, despite the quality delivered, the products like most are untested and slip through quality control. I will be looking for other audio brands.
