Juzear Butterfly 61T Review: The FotM Cycle
The Juzear Butterfly 61T is a $220 IEM from a little known Chinese IEM brand. But it's been building hype since it's release a month ago. In other words, it's halfway to becoming the latest flavour-of-the-month. Fc-Construct gives us a look into its sound and discusses the idea of FotM products.

Sennheiser HD 620S - Does It Deserve A Spot In The 6 Series?
Any headphone laying claim to a spot within Sennheiser's hallowed 6 series needs to have the chops to back it up, and therein lies the question: Is the HD 620S actually good enough to be *the* 6 series closed back, or has the HD 620S been placed in a series it neither lives up to nor competes with? Let's talk about it.

Meze Alba Review: Meze (Mostly) Makes its Mark
If you've heard of Meze, it's for their cult favourites headphones such as the Meze Empyrean, Elite, and 99 Classics. But they've flown under the radar when it comes to IEMs. With the release of their new $160 Alba, Meze hopes to change that. Fc-Construct discusses if the Alba will put Meze on the map.

Elysian Acoustics Pilgrim Review: A Step Along the Journey
Elysian Acoustics a boutique IEM brand from Malaysia that's produced a number of highly acclaimed IEMs. However, they often cost a few thousand dollars and production can take quite a bit of time. Enter the Pilgrim. At $400, it offers a taste of the Elysian Acoustics sound at a fraction of the price. How well does that promise hold true? Fc-Construct takes a look.

Truthear GATe - New Ultra-Budget King?
The Hola was Truthear’s first entry into the ultra-budget space, and it was an exceptionally-balanced offering. Now we’ve gotten its replacement with the GATe, and the question must be answered: after Truthear discontinued what was arguably their most universally-beloved IEM, is the GATe actually a worthy replacement?

Sennheiser HD 660S2 vs. HD 600 and 650: Which is REALLY better?
Sennheiser is the only company that gets the entire headphone sphere excited when they release a new product, but it seems they've forgotten why people love them—and the 6 series—in the first place. Let’s talk about why I think so, how their new HD 660S2 embodies this disconnect, and what I think they can do to fix it.

Crinacle's new DUSK was an IEM that was uniquely positioned to fulfill the wishes of consumers asking for an IEM tuned with the Brüel and Kjaer Type 5128 in mind. However, due to the reliance on the DSP cable to grant that wish, saying "Buy DUSK" isn't quite as simple this time around.

Sennheiser HD 490 Pro: Incrementalist
In a world that doesn't include HD 600 or 650, I might actually take HD 490 Pro over most of the other stuff in its price range. While it's not as good as I had hoped, I still found myself using it without EQ for extended periods of time without glaring comfort or sound issues... and frankly, I’m not sure I could do that with most of the other headphones at its price.
