    Hi everyone, I want to take this opportunity to give a quick update to the community on how tariffs might impact Apos’ operations. This is ...
  • Q & A with James Alvarado

    James Alvarado didn’t set out to start an audio company. He just wanted his headphones to work without spending a fortune or waiting three weeks for a cable to ship. So he dusted off his soldering skills, made a few cables, and ended up launching one of the most beloved names in the DIY audio scene. In this conversation, James walks us through the origin of Hart Audio Cables—from late-night builds in a Texas garage to managing a growing team. We talk about what it means to build a business with purpose, how music always comes first, and why sometimes the best way forward is just figuring it out as you go.
  • Q & A with Yulong Zhang

    Some people fall into the world of audio because of their love for music. For the founder of YULONG Audio, it started with a radio, a screwdriver, and a dangerous level of curiosity. That childhood urge to take things apart—to understand what makes a voice crackle through a speaker—never went away. It just got more refined. In this interview, we talk about how a teenage obsession with FM radios turned into a lifelong pursuit of high-fidelity design.
  • Q & A with Mohil Gupta of OcuClips

    Most people get product ideas in the shower or in the midst of a long drive. Mohil got his during a boss fight. As a lifelong gamer and glasses-wearer, he knew the pain of headset discomfort all too well—so he did something most people would never dream of doing: he solved the problem himself.  In this interview, we talk with Mohil, founder of OcuClips, about what it takes to turn an annoying personal problem into a polished product. He shares the winding path from rough sketches to production-ready parts, how an iOS wizard game led to other ideas, and why every designer should respect the exactitude of the millimeter.

  • Q and A with Jeffrey Yin of SJY Audio

    Some people get into high-end audio because they’re chasing that last half-percent of sonic perfection. Others simply want headphones that don’t make a grand piano sound like it was recorded through a drive-thru intercom. And then there’s Jeffrey Yin of SJY Audio, who looked at the entire industry and said, “Watch this.”   In this Q&A, we chat with Jeffrey on why he started making headphones, how he landed on forged carbon fiber for the ear cups, and why the Horizon Closed Carbon’s rectangular drivers give it an acoustic edge. There's a method to his madness—and about 60 driver iterations to prove it.

  • Meze 105 AER Reviews Compendium

    Tom at Apos here. What I love more than anything else is a reasonably-priced banger: the 6XX, the Sundara, the R70x Refine, the Gremlin (shamelessly tooting my own horn here). The list goes on and on. Do we have another on our hands with the Meze 105 AER? A classic isn't born overnight, but the opinions of trusted reviewers go a long way, so let's see what they think.  We’ve compiled reviews from across the web. What you’ll find here are bite-sized TLDR snippets of the full reviews (which you can access with the provided links). We’ll continue updating this page as more reviews come in.
