Geshelli Labs Archel 3S Pro — The Swiss Army Knife of Headphone Amps

This is part two of three in my Geshelli Labs special. We started with the J2S DAC; today it’s the Archel 3S Pro, the middle child of Geshelli’s headphone amplifier range. At $369.99 base, the Archel 3S Pro sits below the flagship Erish 3 Pro in the lineup but does something the Erish doesn’t — it gives you tone controls. Real, proper, hardware Baxandall bass and treble knobs. In 2026. From a small audiophile shop. I love everything about this idea.

Geshelli Labs Erish 3 Pro [E3] — Discrete, Balanced, and Honest

This is the third and final review in my Geshelli Labs special. We’ve done the J2S DAC, we’ve done the Archel 3S Pro mid-tier amp, and now we arrive at the flagship of the headphone amplifier range — the Erish 3 Pro. It is the most expensive of the three pieces in this stack at $549.99, and unlike the Archel 3S Pro it doesn’t have tone controls, doesn’t have RCA input, doesn’t have a single-ended headphone output. It is balanced in, balanced out, and that’s it. This is Geshelli stripping away everything that isn’t the signal path and going for it.

Geshelli Labs JNOG2 Socketed [J2S] — A Florida Garage With Big Ideas

This is the first in a short series of three reviews looking at the current Geshelli Labs lineup. Geshelli is a husband-and-wife operation out of Florida — Geno builds the gear, Shelley runs the shop, and the whole thing has the feel of a small workshop where someone actually picks up the phone when you ring. After living with their J2S DAC, Archel 3S Pro and Erish 3 Pro for a few weeks I wanted to write each one up properly, because there’s something genuinely lovable about what they’re doing.

Koss Portapro- The Value Bet Headphones

Warning….I Love these budget retro style headphones :-)

Introduction: A Walk Through History In the fast-evolving world of audio technology, few headphones have stood the test of time as remarkably as the Koss PortaPro. Launched in 1984, these iconic headphones have become a symbol of enduring quality and retro appeal. Designed by John C. Koss, the PortaPro was a revolution in portable audio, promising high-fidelity sound in a compact, foldable design that was quite ahead of its time. Even today, they remain a beloved choice among audiophiles who appreciate their mix of vintage style and excellent sound performance.

Sennheiser HD 600 - A History of Excellence

I Discovered my love of listening to music on headphones in 1997 when i moved into an apartment/ Flat. For the sake of the neighbourly goodwill, i started moving my listening to high quality headphones.

I discovered quickly that for modest outlay compared to my full size hifi components a high quality reproduction could be acheived. I have upgraded my orinal setup immesurably, however the ehadphones i purchased back then, the HD600 just improves as the source and amplification does. The best investment i have made in a headphone.
