Monster Cable was started in 1979 by an audiophile engineer who experimented with copper qualities and different wiring methods to see if cables can be engineered to work and sound better.

By 1980, their popularity spread via word of mouth, fast forward to the future, the company continues to produce premium cables, one of which, the Classic Balanced XLR has garnered high ratings and recommendations.

While many of their claims of sound quality enhancement are disputed by those in pro audio circles, they do make cables that are solid and sturdy.

A number of reviewers reported that the Monster Classic XLR cable surpassed their expectations. Some even commented that they believed the resulting sound was clearer, and most were happy with how durable and different feeling the cable is compared to cheaper counterparts. A very interesting positive review also praised the company's customer service, where in their Monster Classic XLR cable was quickly replaced when they encountered a problem.


There were a few who experienced issues out of the box, but they were helped by the company to get the cables either fixed or replaced. Others complained about the price, stating that this cable is not even Monster's top of the line product.


Although we used to recommend the Monster Classic for DJs and small band setups, after a thorough review and updated research into XLR cables in September and October 2017, we found that there were new options that had higher ratings. Note that the ratings for this cable remained the same as they were when we recommended it, however there are now more highly rated options which you will find in our updated guide to The Best XLR Cables.
