Unique Melody MEST IEM


Naturally isolating with cutting edge tech

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 MEST is a hybrid IEM that features one dynamic driver, one bone conduction driver, and six balanced armatures. It’s a great option for exacting audiophiles looking for a portable option that lives on the cutting edge of IEM technology and design. 

Six balanced armatures for extreme detail and clarity

The MEST features three 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 MEST 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 six 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. 

Bone conduction driver

In addition to its three balanced armature drivers, the MEST features a bone conduction driver. Unlike traditional drivers, bone conduction drivers deliver sound directly to your inner ear through the bones of the skull. If this is starting to sound like techno-babble, you should know that you listen to bone-conducted sound every time you speak. That’s right--bone-conducted sound is how we’re able to hear our own voices.
