Black rhodium Proto 250 length 3 metre pair with black rhodium banana plugs fitted at both ends cables are in excellent. Condition
The £50 asking price for the Black Rhodium Proto 250 is a genuine bargain, sitting well below the 25th percentile of £363 from your ground truth data and far under the current retail of £110 for the 3m pair. This is not just fair; it is a strong deal that makes the listing an immediate buying opportunity for anyone seeking entry-level performance at a fraction of the cost.
As Black Rhodium’s entry-level range, the Proto 250 excels as a reliable, affordable headphone extension or professional cable that delivers excellent connectivity without the premium price. Its timing is ideal given the sale price drop from £250 to £60 for the 5m version, meaning you are securing a well-regarded, original-owner item at a price that reflects true value rather than market hype. No caveats apply here; this is a clean, worthwhile purchase for the budget-conscious enthusiast.
