Unique Melody Mason V3+ IEM


Extreme detail and clarity

Unique Melody is a company best known for their mid-tier and hi-fi IEMs. But since their founding in 2007, they’ve developed products and filed patents in the Bluetooth, planar magnetic, piezoelectric, and bone conduction driver markets. 

The Mason V3+ is an IEM, or in-ear monitor, that features sixteen balanced armatures. Carbon fiber shells offer robust (and stylish) protection. Silver alloy conductors provide high conductivity, while the titanium-gold sound tube is corrosion resistant. All in all, it’s an IEM that should last a lifetime. 

Sixteen balanced armatures 

The Mason V3+ features sixteen balanced armatures per monitor. Unlike traditional IEMs that use a single dynamic driver, balanced armatures are smaller, lighter, and provide greater output for less power. Inside each balanced armature, a small reed is balanced between two magnets (hence the “balanced” in balanced armature). The magnets vibrate the reed, and the reed’s motion is transferred to a diaphragm. 

By allocating different frequency ranges to different balanced armatures, the Mason V3+ is capable of producing a more detailed and clarified response. Think of it like this. You give a muralist a single hour to paint a mural on a large wall. They may be able to paint the whole thing, but the finished product won’t be very detailed. Now imagine you give that same task to sixteen muralists. By splitting up the job, they can deliver a far more detailed finished product. 

Naturally isolating

Because the eartips of IEMs fill up your ear canal, they’re naturally isolating. They’re not as isolating as noise-cancelling IEMs or headphones, but much more so than open backs. They’re a great choice for commuting, traveling, and other scenarios in which privacy is important.
