Frequently asked questions
How much does the Cisco 521 Headset - Mono - Mini-phone (3.5mm), USB - Wired - Over-the-head - Monaural - Supra-aural - Uni-directional, Electret, Condenser Microphone - Black (CP-HS-W-521-USB-RF) cost?
Uniqcli sells the CP-HS-W-521-USB-RF for $125.18 against a Cisco list price of $179.77. Add it to your cart and submit to confirm current pricing, stock, and lead time. Lower pricing is available for volume orders, Government Purchase Card (GPC) buys, and emergency or urgent acquisitions. Free US shipping on orders over $2,500.00.
Is the CP-HS-W-521-USB-RF TAA compliant and available for government and DoD buyers?
Often yes — it depends on the unit. Cisco manufactures the CP-HS-W-521-USB-RF in several countries, so Trade Agreements Act (TAA) status varies by production lot. Uniqcli is an authorized Cisco partner: we confirm the country of origin before shipment, and if a given CP-HS-W-521-USB-RF is not TAA-designated, we will source a TAA-certified equivalent of the same model. Either way the result is DoDIN APL-ready procurement for US federal, DoD, state, local, education, healthcare, and enterprise buyers, with Government Purchase Card (GPC) acceptance and FAR-based urgent and emergency acquisition support. Request a TAA-compliant quote for the CP-HS-W-521-USB-RF and a specialist will confirm compliance, price, and lead time — usually within one business day.
Can I buy the CP-HS-W-521-USB-RF as a single unit or in volume?
Both. Order a single CP-HS-W-521-USB-RF through the cart, or ask about lower pricing for volume orders, Government Purchase Card (GPC) purchases, and emergency or urgent (FAR-based) acquisitions. There is no payment up front: we confirm availability and the final total before invoicing.
Where can I find the CP-HS-W-521-USB-RF datasheet and specifications?
The official Cisco datasheet is available on this page (open the gated datasheet for the full PDF), and the Tech Specs section lists ports, power draw, dimensions, and licensing for the CP-HS-W-521-USB-RF.
Need the CP-HS-W-521-USB-RF TAA-compliant for federal or DoD?
Cisco builds this model in multiple countries, so TAA status depends on the production lot. We confirm country of origin before shipment — and if a unit isn't TAA-designated, we'll quote a TAA-certified equivalent of the same model, DoDIN APL-ready and GPC-payable.
