Most of the guys building high-end speaker systems or setting up professionel studio racks end up here, looking for a connector that won't degrade the signal path, and we've been making the HH1058 for them for a while now — it's a right-angle 4mm banana plug with a carbon fiber shell and gold-plated brass core, which is pretty much standdard for keeping corrosion away and transmission clean.
The spring matrial is beryllium copper, so you get better conductivity and durability than standard brass springs, and our company offer it in red and black color coding for polarity, with a nickel plating option too if gold isn't your thing.
What you're looking at is a 4mm diameter connection that's CE and RoHS compliant, and we usually have stock for bulk orders in the 500-unit range or so, but custom packaging is avaliable if you need your own branding on the bags.
One thing we've learned handling these is that the right-angle design really helps in tight rack spaces where straight plugs just won't fit, though it's not ideal for every setup — if you're wiring a patch bay with straight runs, you might find it awkward.
Basically, when you order, you get the plugs in bulk or custom packaging depending on your MOQ, and our company can provide a COA and TDS with each batch, but confirm teh lead time because of that it usually runs about 20 days or so from order to shipment.
We can work with MOQs as low as 100 pairs for standard color and plating, but if you need custom packaging or a specific finish, we’ll discuss a minimum based on your order size.
Lead time is typically 15–20 working days for orders up to 1,000 pairs, though custom packaging or plating might add a few extra days.
Yes, the HH1058 plugs are CE and RoHS compliant, and we can provide the certificates with your shipment upon request.
The spring is indeed beryllium copper. It gives better conductivity and holds its tension longer than standard springs, so your connections stay tight even after many plug-unplug cycles.
The carbon fiber shell isn't just cosmetic—it’s lightweight, non-conductive, and helps reduce signal interference, which is key for clean audio in professional setups.
