64 Audio tia Trió IEMs


  • Anodized Aluminum Shells
  • Universal-Fit w/ TrueFidelity Foam Tips
  • Internal apex™ Technology
  • tia™ system: tia™ drivers, single-bore, acoustic chambers
  • FXC – Frequency eXtension Chamber
  • LID Technology

The 64 AUDIO tia Trió™ Universal-Fit earphones are the perfect balance between reference quality sound and personal entertainment. Featuring a fully-tubeless design, the breakthrough patent-pending tia™ system consists of the tia single-bore, tia acoustic chambers, and the proprietary open balanced armature tia drivers. You won’t miss a beat or a bass line thanks to the dynamic driver that provides weight and punch to the trio’s musical low end. The Frequency eXtension Chamber allows for superior mid-range control on a back-vented dynamic driver and paves the way for perfectly placed mid frequencies, giving vocals and instruments a remarkably natural sound. Detailed and reliable upper mids are relaxed in presentation and layer easily into the smooth and extended ‘tia top-end’, the signature of any IEM bearing the tia high-driver. Additionally, internal patent-pending apex™ technology vents air pressure from the ear canal for fatigue-free listening. All of this technology is housed in an ergonomic shell machined out of a solid piece of aluminum. With a stunning brushed aluminum faceplate, the 64 Audio tia Trió is a durable and equally elegant addition to the T-Series line-up.

Like all 64 AUDIO universal-fit products, the tia Trio earphones are inherently noise isolating and are designed to work well with a wide range of personal audio devices as well as all Personal Monitoring Systems.

    Very fun, detailed and balanced

    The sub bass and mid bass is close to sony ier-zir with a touch less slam. I would say audiophile quality and bass head approved. Mids and vocals are more forward than zir but not to much. Treble is as detailed as zir but cymbals are slightly back from air. You will see on Crinnacle’s frequency response a slight dip in upper mids. The treble details are all there just some are a little back from the zir. This is a personal preference, the zir is more forward the trio is equally detailed but a little less forward. This is all a very picky/personal opinion. You would not be disappointed and the price is worth it.


    Never thought something so small could sound so amazing!

    I started looking into buying my first pair of IEMs after purchasing the Fiio M11. Frankly, I didn't know that "earbuds" of this quality existed on this planet. Now let me give you some background. I tend to filter "price high to low." I believe that you get what you pay for. So I was looking at IEMs $1500 or more. I worked with the Audio 46 staff (who are excellent by the way) over the phone to help decide on and IEM. I did spend a great deal of time contemplating spending $3600 on the Fourte which I'm sure are amazing. The reality is that I simply didn't have that budget at this time. So back to the Trio. They are stunning! I don't see how IEMs can get any better. The music is crisp and full and vibrant. It's hard for me to even realize I'm not using high end open back headphones. And they even come with a hard case with cleaning tools. Highly recommended. You won't be sorry!
