When you're comparing business phones headsets, the real question is where your conversations happen. Are you sitting at a fixed desk, splitting calls across multiple lines, or are you moving between meetings and countries, trying to understand someone speaking another language? These two devices answer very different parts of that question, and they sit at very different prices. Before you compare spec sheets, decide whether your communication is anchored or mobile. That choice matters more than the price gap.
Quick verdict
If your day revolves around a dedicated office phone with room for many lines, the Poly Edge E450 IP Business Phone is the more complete station. If you need a portable translator you can wear while talking to someone in another language, the 144 Languages Translator Earbuds are the more portable, pocketable pick. They are not direct rivals; they are two tools for two jobs.

Where each product wins
Choose the Poly Edge E450 when your work is built around a fixed desk. It gives you 14 programmable line keys that paginate to 44 contacts or features, plus call waiting, conference calling, talking caller ID, and voice memo recording. The dual Gigabit Ethernet ports and PoE make it a natural fit for an office network, and the wall-mountable design helps reclaim desk space.
Choose the 144 Languages Translator Earbuds when your work is built around movement. They deliver two-way real-time translation in a wireless ear-hook format, support touch control, and display both audio and text as you speak. The charging case keeps the kit organized, while the new condition and compact design make them an easy addition to a travel bag.
Product notes
#### Poly Edge E450 IP Business Phone
At USD 129.99, the Poly Edge E450 is the larger investment here, and the used condition is the main thing to weigh. What that money buys is a serious desk-phone foundation: a headset jack, amplified sound, call waiting, and Energy Star-qualified operation. The physical reality is that this phone lives on a desk or wall rather than in a pocket, so it suits someone with a fixed workstation. That fixed location can actually be a benefit when calls arrive all day. If you've been juggling calls on a mobile device and want a stable, always-there phone station, this is the one.
#### 144 Languages Translator Earbuds
The 144 Languages Translator Earbuds are the mobile option, and they are sold as new with a charging case and a 350mAh charging box battery. The reason to pick them is simple: with 144 languages covered, they put multilingual support into a shape you can carry in a pocket. The compatibility layer is broad, covering universal devices as well as Apple, Google, LG, and Samsung phones, so pairing shouldn't be a headache no matter what you carry. The trade-off is the ear-hook form factor-you're wearing small earbuds, not an office headset with a microphone arm, and the entire experience is tied to your phone. For travel and conversations that cross languages, that's an easy trade to accept.
Final choice by use case
- Fixed desk or multi-line office: Poly Edge E450 IP Business Phone.
- Mobile work, travel, or conversations that cross languages: 144 Languages Translator Earbuds.
If you need a stable office anchor, the Poly gets your calls together in one place. If you need a lightweight language bridge that travels with you, the earbuds are the simpler everyday pick.
