this is an awful product, it looked used when i got it, the plastic of the case was not straight and level and when trying to put it in the tape player it spent most of its time ejecting itself. When i did get it working the sound quality was pants no matter what adjustments where made and most of the sound came out of only one speaker. You'd be better off saving your money and buying a cheap headunit for your car.
Well, not much is the answer. I know this product is very cheap and you shoud expect the sound quality to be just that too. I followed advice of turning it down etc that people have wrote, but how far do you actually have to go?! The sound quality is frankly terrible and I would advise anyone to go for a more expensive one, it is a massive difference.
I ordered this item not having massive hopes but as more of a ' i wonder how good a £2 i-pod/mp3 adaptor can be' kind of hope, and i must say i wasn't disappointed!
This handy little thing means i can listen to my i-pod/mp3 player in the car without haveing to spend £15-£30 on a radio transmitter and it even comes with a mobile phone adapter (doesn't fit my phone but still a bonus)
You may have to twidle with the volumes to get it spot on, but it took me about 5-10 seconds max to do this.
