2 years back i got a pair of nuforce ne-6. I started listening to them and become a fan of its bass and quality. Unluckily, after an year, it started having problems. Since then i have monitored many earphones in 60-70$ category and didnt find any with same sound quality and bass. I can extend my budget also, please suggest a pair with atleast equivalent bass and wideness of sound. If anyone can provide me instock links of nuforce ne-6/7s, i can buy them also again. I am tired of searching. Please suggest.
