Enough Clarity to Sate Anyone’s Appetite

You want to hear as much as possible when you’re onstage. And if you’re in the market for a new pair of universal earphones, Sweetwater recommends the Westone Audio Mach 50 5-driver Universal In-ear Monitors. These outstanding in-ears offer high-end performance with a justifiable price tag. Each monitor carries five balanced-armature drivers in a 3-way configuration. There’s a single bass driver, two midrange drivers, and a pair of treble drivers to provide expansive mids and a silky-smooth high end. You’ll love the secure, ergonomic design during long rehearsals. Plus, Westone Audio included their detachable Linum Estron SuperBax cable for clear audio transmission. Mach 50 earphones aren’t just limited to seasoned stage professionals, either! They’re very well-suited for critical listening and pleasure listening alike.

Welcome to the Mach Series

Westone Audio’s Mach Series of in-ear monitors leverage the company’s decades of engineering experience to outfit users with the tools they need to make and enjoy music at the highest level. The engineers at Westone Audio pulled out all the stops to create an ergonomic design that’s comfortable to wear for hours on end. Other top-notch features include ultra-durable Estron T2 connectors, upgraded cables, and Westone Audio’s signature balanced-armature drivers. Experience sound the way it’s intended to be heard with Mach Series Professional In-ear Monitors.

Five balanced-armature drivers create an expansive soundstage

The Mach 50 professional in-ear monitors feature five balanced-armature drivers in each ear. The drivers are laid out in a 3-way configuration. One driver creates thumping lows, two divers handle the wide midrange, and two drivers supply a silky top end. What results is a smooth and beefy listening experience that’s perfectly suited for stage use and pleasure listening. Mach 50 in-ears feature a 3-way passive crossover for clear, consistent audio throughout the impressive 8Hz-20kHz frequency response. Try them out and experience the expansive soundstage for yourself.

T2 connectors dramatically increase durability

Premium drivers and comfortable ergonomics don’t mean much if you can’t hear your audio! One of the many reasons Sweetwater is excited about the Westone Audio Mach Series monitors is that they include T2 connectors on each earphone. The T2 connector system delivers rock-solid connection in a streamlined package. The design prevents intermittence, lessens socket wear, and withstands greater pull forces. Plus, the T2 connection system carries an IP-67 rating that provides robust protection from dust and water. Low profile and tough as nails, T2 connectors ensure your earphones will last longer.

Comes with Linum Estron SuperBaX cable

Your new Mach 50 in-ear monitors come with a Linum Estron SuperBaX earphone cable. This cable is sturdy and reliable, thanks to its quad-twisted cable design. Inside the quad-twisted architecture lie 168 strands of silver-plated copper for clean and clear signal transmission with zero microphonics. The SuperBaX earphone cable features Estron T2 connectors, a significant upgrade from MMCX connectors. T2 connectors offer a sleek look and solid connection. Westone Audio also tells Sweetwater that T2 connectors decrease intermittency and seized cables by over 99%. The SuperBaX cable offers the pure sound needed by musicians, audio engineers, and audiophiles.

Helpful accessories get you started on the right foot

A good pair of universal in-ears is no use if you can’t listen to them! Westone Audio includes a 10-piece foam and silicone ear tip “fit kit” with all Mach Series earphones. Just select the size and style of ear tips you want to listen to, install them, and get listening! And once you’re done, store your Mach 50 in-ears in the included crush-proof, watertight, and dustproof Pelican case. Of course, you also get a cleaning tool to keep your monitors free of gunk and grime. When you buy Mach 50 Professional In-ear Monitors from Westone Audio, you get plenty of bang for your buck.

  • 5-driver in-ear monitors for pro-level musicians and critical listening applications

These are expensive but real killer I like the newer hearty construction and the cabling.

Mach 50 ears
I spoke to Kenny ( my engineer) and he always gives great educated advise. I am in a band Medicine man and was having issues live with 2-driver ears. After speaking to Kenny i was sold. He gave solid advise and not sales advise. This is why i come back time after time. He calls me everytime to make sure i'm good. Sometimes he call just to check on me. I have used the mach 50's and it sounds like my head is inside the music. Kenny thanks brother, these things are fantastic.

Mach 50
I use them almost every day. Clean crisp sound thoroughly enjoy them. I would recommend Westone IEM
Expected to get more than 14 months out of them
For the money, these IEM'S should not be breaking off at the base of the connector wire. My last gig I went to disconnect the ear bud from the mini jack on the wire and it completely snapped off. As always, I was careful not to tug from the wire. It literally just fell off when I disconnected the coupling... No happy with this at all. These IEM's were over $. I may have to go back to SHURE. Never had a quality product problem with them before. I am contacting my sales Rep and see if there is anything that can be done. I'm not going to hold my breath though. May have to go another way
Music background: Musician for 40 + years. Predominantly a Vocalist
Good sound , horrible design
Bought these just over two years ago, so just out of warranty, noticed the right ear piece kept cutting out causing me to loose click tracks in both ears for some reason. I turn my head while playing and they cut out. So, I Paid way too much for a replacement chord and the problem still happens. It's the right earpiece connector. So now I'm out of luck with no IEM's. Wish I hadn't talked my whole band into getting these things too. Not Sweetwaters fault tho. Just not designed for longevity.
