Went in to get a wireless system for my trumpet. Jason got me sorted on the spot and hooked me up with a better price than was available online. Thanks team!

Quick service and reasonable price. Angus was helpful and transparent.20/07/23 Update. I had an issue with some equipment that I purchased from these guys, and true to form, they were supportive and gave me consistent feedback on the progress of my concern. Elliot and Darren were incredibly committed to getting me a satisfactory result. I have recommended Factory Sound to my mates because I actually believe that they will be taken care of.

The only place to buy pro audio gear from. Been coming here for over 20 years, and a lot of the same staff still look after me. Says a lot about their business. The best service, advice and gear every single time. If they don’t have it, they’ll get it for you. No need to worry about pricing, theirs is ALWAYS the best. All the staff go out of their way to help you, and will always get back to you. Cant’ recommend this place enough, 5 stars doesn’t seem like enough.
