šŸ”¶ KOSS ESP/95x

Get the nectar hive as an upgrade.

What the heck is this? He builds them by himself? I’m actually more interested in his DIY amp.

I have ordered the Yaxi pads, a set of purple Grado’s also for one of two pairs of jacked Grados I have that I’m going to detachable mod.

Oh trust me it’s legit. I’ve heard from several reputable sources that it can go toe to toe with the best in its price category. It is an upgrade over esp/95x for sure

Doesn’t really make up for the fact that just a decent stax amp by itself costs as much as an amazing planar setup

If you’re looking for the cheapest option it’s likely finding some sort of electronic tinkerer/enthusiast to take a look at the amp, just networking around with friends or something until you find someone who might be able to help. You could try and find a PC or phone repair shop, but I’d be slightly concerned about what they potentially might do depending on the place, I’d personally make sure you didn’t take it to a chain location as they’re both more likely to either not help or potentially screw it up (at least from my experience with computer repair places in the US, the chain stores typically suck ass).

You could get a new energizer, but if you did you might as well upgrade it, yes they are expensive for the good ones, but you will get a jump in sound quality that could still potentially make it worthwhile

Very satisfied with the Yaxis, though they were surprisingly tough for me to stretch on!
I have not had the Dekoni pads to compare them with, but I’m pretty confident I’d prefer the Alcantara contact patch over the fenestrated. Not sure if center-imaging is a bit less focussed now, but vocal timbre does feel more natural and I think its a little less honky in the mids. Much-improved long-term comfort, and I love these ear speakers, just an effortless presentation I really appreciate. I try not to bring them out too often to preserve them from the horrors I’ve read so much about.

Hello - I’m new to the community and was just desperate looking for some answers.
I’ve bought ESP 95X - used but it included 220V adapter. While trying other 9V adapters with replaceable ends, I could not find any luck in powering the energizer.

It FLASHES red, once I turn it on. The AC adapters that had LED light of some kind was either blinking along with the energizer or have turned off.

Is there someone who knows what 110v adapter works with the energizer - or do you know if the flashing red light is sign of something else? Thanks

Welcome to HFGF! Just so I can better understand: you bought an ESP95X for 220V and are using a Transformer to step down for 110V? Or did you change the Power supply included with it?

Thanks!

I meant that I’m not using the included power supply/adapter and instead bought a separate ā€œUSā€ adapter that meets the spec.

I’m pretty ignorant in this area - but someone recommended this in the DROP community, and it’s not ā€œworkingā€

Hum, I see. According to the photos I’ve seen and people on the Drop post about the 95x, it should use a 9V 1A power supply. The one you posted should be enough in terms of power, just make sure you turned the red ā€œknobā€ to 9V.

If the voltage is settled correctly and it still doesn’t work, it would be good getting a multimeter or similar to check if the output voltage is actually 9V or if the power supply is wrong. If it’s fine, Tham maybe the unit itself is at fault.

Sometimes this very cheap power supplies have fewer and worst quality components, so one thing to look for is a better unit. Ifi is particularly well regarded here so they are a interested option. Meanwell also comes to mind.

Thanks for the suggestions.
Will try the multimeter method first and possibly try other adapters. Thanks!

And what also could help is a pic of the included power brick, because stax energizer have the positive on the mantle of the jack, also switched compared to nearly every other power supply :wink:


I should’ve included in the first place, thanks!

Ok so the adapter is wired normal, so most power supplies should work

Careful! 9V happens to be where a lot of guitar pedals sit, and they are centre negative.

Adapters are not dirt cheap but available.
Curious what the thoughts are on points of diminishing returns folks have found with using Stax energizers with the Koss earspeakers. Is the Koss unit so bad? Has anyone had experience using Stax earspeakers on the Koss energizer?

I bought the Yaxi pads from Japan. They’re smaller than stock, and it was a little tough to stretch them on.

They’re way more comfy than stock. Smoother and softer. I just wish they were a little thicker.

They maybe add a little more low end over the stock pads, but overall the sound is still amazing and I couldn’t hear any negative differences. I think they improved the sound.

They arrived in like 5 days or so from Japan to Quebec, I was pretty surprised! For $76 CAD landed I’m happy with them.

I bought this guy to test if I could do a modern take on the classic battery pack the Old Koss ESP 950 used to have. It totally worked! So technically you could just get this cable and use any powerbank/USB-C PD Charger with the 95X.
