HP Poly SHS 2459-01 PTT Amp NC7MX Connector (REF SHS 1890)

Product Overview

AI-generated summary

At £120.50 ex-VAT, this HP Poly “PTT amp” style connector is the sort of item you buy once you already know you’re missing a very specific piece of your existing setup. The real-world question isn’t “is it good?”—it’s “does it match your headset/radio/console configuration exactly?” If it’s the correct replacement for your Poly SHS accessories (and not a close-enough substitute), it’s a sensible fix because you’re restoring the intended push-to-talk workflow without having to re-engineer anything. For estates like contact centres, security ops, or any shift-based comms where downtime is painful, that kind of compatibility is worth paying for.

I wouldn’t buy it speculatively. If you’re still deciding on an audio solution, or you don’t have the exact reference/part pairing identified in your kit, the odds of wasting money go up—audio accessories are rarely universal. Also, if you’re replacing it because of poor audio or intermittent PTT, double-check whether the fault is actually in the connector versus cabling, radio interface, or a configuration setting on the host system. In short: buy it if it’s a confirmed match to an existing Poly SHS build; skip it if you’re trying to “improve” or “make it work” without verification.
