The openings for the 2 3.5mm plugs are a bit close together. If you are using 2 premium cables from monoprice, then the two cable ends will both barely fit in the plugs, which sometimes causes one or the other to pop out a little bit. enough to lose signal in one channel sometimes.
PROS: high quality low price
CONS: The openings for the 2 3.5mm plugs are a bit close together
Bought this to connect to my tube headphone amp., splitting to the headphones and the second to the power amp. Results are good as expected. The convenience of not having to disconnect one or the other for switching modes.
PROS: Convenience for any pre-amp.
CONS: Splitter output connections are too close together. Otherwise works
A very useful adapter to have for connecting speakers with RCA jacks to your laptop's headphone input for great sound, or to connect your laptop to your stereo using the headphone input on your laptop/computer to the RCA jacks in the back of your stereo.
