Get a et a phono stage similar to this one. On the back of your turntable there is a switch for the built in phono stage switch it to Line and then connect the turntable to the external phono stage and then you should be able to listen through your headphones.Here is an Amazon link.I have an Audio Technica LP60XUSB and would like to use a set of wired AKG K72 over ear headphones that come with a 6.3mm jack. Unfortunately the turntable doesn't come with an aux nor do the Edifier speakers so I'm a bit stuck. I would happily change the turntable for a bluetooth enabled one and use wireless headphones but the width of the gap that I can put the turntable in is maximum 400mm.
Does anyone have any kind suggestions other than buying new equipment as i simply can't fit anything bigger where it needs to be. Sadly the Pro-ject Debut Eve 2 is 15mm too wide.
