My Sennheiser (CX300?) earphones broke last night and I'm in need of replacements. Are there any which can be recommend as an alternative with decent quality (but not bass heavy)? Because direct replacements will cost around £32 (I paid £10 on offer) and I only like to spend up to £20. In the past I've used Sony earphones and while they had decent quality, they had hit or miss reliability. Thank you.
