Last updated Aug 11, 2026

Choosing between business phones and headsets usually comes down to how you take calls: at a desk with a full IP phone, in a shared workspace with a simple handset, or on a Teams-based USB setup. This guide looks at four current listings: two Poly Edge E450 desk phones, a ShoreTel 230 two-phone lot, and a Yealink MP50 USB phone. Listed prices range from $10.99 to $109.95, so the right pick depends on line capacity, connectivity, condition, and whether you need a phone or a headset.

Quick take

  • If you need a 14-line desk phone with Bluetooth and a headset jack, the Poly Edge E450 listings cover that profile.
  • If the desk phone itself needs Wi-Fi, the Poly Edge E450 with Wi-Fi & Bluetooth listing calls that out for USD 105.99.
  • If you want two phones with stands and headsets at the lowest listed price, the ShoreTel 230 lot is USD 10.99.
  • If you work in Microsoft Teams and want a dedicated USB phone, the Yealink MP50 is certified for Teams and listed at USD 69.99.

Product notes

Poly Edge E450 Corded IP Phone VoIP Business Phone - 2201-87030-001

At USD 109.95, this is the highest listed price in the group, but it is the only Poly Edge E450 that does not mention Wi-Fi in its title. The used phone lists 14 lines, HD Voice, amplified sound, Bluetooth, a headset jack, talking caller ID, voice memo recording, and a wall-mountable design. If your desk already has an Ethernet connection and you want Bluetooth for a headset or mobile, this wired-and-USB-C listing gives you the full desktop phone layout. The limitation is condition and connectivity: it's used, and the listing does not present Wi-Fi as part of the package, so plan for a wired network connection.

Poly Edge E450 Corded IP Phone VoIP Business Phone with Wi-Fi & Bluetooth

The listing that includes Wi-Fi is the Poly Edge E450 with Wi-Fi & Bluetooth, listed at USD 105.99. That price is lower than the other E450 listing, and the title states both Wi-Fi and Bluetooth. The used phone also lists 14 lines, HD Voice, amplified sound, conference-enabled, Energy Star qualified, a headset jack, talking caller ID, voice memo recording, and a wall-mountable design. If wireless network connectivity from the desk phone matters, this is the listing that explicitly includes it. The limitation is shared with the other E450: it's used, so the piece is not new even though the feature list is full.

Lot of 2~ ShoreTel 230 IP 230 VoIP Business Phones - Black Stands- Headsets

The ShoreTel 230 lot gives you two used VoIP phones plus black stands and headsets for USD 10.99, the lowest listed price here. The ShoreTel 230 model in the title lists three lines. That makes it a sensible choice for a second office, training desk, or any setup where a pair of simple desk phones is better than one higher-capacity unit. The limitation is line capacity: at three lines per phone, it doesn't come close to the 14-line Poly Edge E450 listings in this roundup. If you need Bluetooth or HD Voice, the Poly listings are the ones that include those details.

Yealink MP50 Business USB Phone Certified For Microsoft Teams NEW open box

The Yealink MP50 is a USB phone certified for Microsoft Teams, listed at USD 69.99 as a new open-box unit. The listing type is Headset System, so this is a handset-style accessory for a computer rather than a 14-line desk phone. If your daily work happens inside Teams and you want a physical handset for calls, the MP50's Teams certification is the concrete reason to pick it. The limitation is the condition and scope: it's open box, and the listed details focus on the MP50 itself, not on multi-line desk-phone features like the Poly Edge E450 listings.

Final recommendation by use case

  • For a wired desk phone with 14 lines and Bluetooth: Poly Edge E450 Corded IP Phone - 2201-87030-001 at USD 109.95.
  • For a desk phone that also connects over Wi-Fi: Poly Edge E450 with Wi-Fi & Bluetooth at USD 105.99.
  • For a two-phone setup at the lowest listed price: ShoreTel 230 lot at USD 10.99.
  • For a Microsoft Teams USB handset: Yealink MP50 at USD 69.99.
