If you want a dedicated, long-range DECT headset for private calls while watching TV, choose Plantronics Poly Savi 7310; if you need Bluetooth flexibility, USB-C/A connectivity, and longer talk time, choose Yealink BH70. For ordinary television listening, neither is presented as a conventional stereo TV headphone, so check your TV’s connection options before choosing. Poly is the more specialized office-call system; Yealink is the more adaptable wireless headset.
Plantronics Poly Savi 7310 vs Yealink BH70 at a Glance
• Plantronics Poly Savi 7310: A DECT headset with up to 580 feet of line-of-sight range and up to 13 hours of talk time. Its single-ear design is geared toward calls, not immersive TV listening.
• Yealink BH70: Bluetooth connectivity, a USB-C/A dongle, and up to 35 hours of talk time give it more connection flexibility. Its mono, on-ear design still isn’t a conventional two-ear TV headset.
• Poly’s strongest case: Sensitive conversations and desk-phone or softphone work, supported by 256-bit AES encryption and a noise-canceling microphone with Acoustic Fence.
• Yealink’s strongest case: Longer call sessions and modern workplace use, with a three-microphone system, flip-up mic mute, and compatibility with several meeting platforms.
• Choose Poly for DECT range, enterprise call privacy, and compatible desk-phone setups; choose Yealink for Bluetooth, USB dongle connectivity, and longer stated talk time.
The Savi 7310 is a single-ear DECT headset system built around professional calling. Its headline practical advantage is reach: the stated line-of-sight wireless range is up to 580 feet, with up to 13 hours of talk time. That combination may suit someone who needs to move around an office while staying on a call, rather than someone settling in for a movie.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Its security emphasis is unusually specific. The system is designed for DECT Security Step C and includes 256-bit AES encryption. Poly also describes a noise-canceling microphone with Acoustic Fence technology intended to help keep nearby conversations from being picked up on calls. Those traits make the Savi 7310 a logical fit for environments where call privacy matters, such as healthcare, finance, government, or contact-center work.
I would skip it if your main goal is a private, immersive soundtrack from a television. It has a single-ear wearing style, and its listed wireless connection is DECT rather than Bluetooth. The supplied facts don’t establish a direct connection to a TV, so check compatibility before buying for that purpose. For a work phone or supported softphone, though, its broad desk-phone compatibility and Poly Hub softphone support are more relevant strengths.
The BH70 is a mono Bluetooth headset with a USB-C/A dongle and a charging stand. It is designed for calls across workplace platforms, with stated compatibility that includes Microsoft Teams, Cisco, Zoom, and Google. Its Bluetooth range is listed as 50 meters, and its talk time is up to 35 hours. That longer battery figure may matter to remote workers or anyone who stays on calls for much of the day.
The BH70’s microphone setup is another practical distinction. It uses three microphones and Yealink’s noise-reduction approach to help isolate the speaker’s voice. The mic arm can flip up to mute, and the headset also includes a mute button with an LED indicator. A busy light can signal that you are on a call. These are call-management features, not evidence of a dedicated noise-canceling experience for television audio.
For TV watching, the attraction is its Bluetooth connection and its stated 20 Hz–20,000 Hz frequency range. But the product is still a mono, on-ear work headset, not a conventional pair of stereo TV headphones. Its provided information does not establish deep bass performance or guarantee that it will pair with a particular television. If you are searching for deep bass wireless headphones for TV watching, the specs here aren’t enough to call the BH70 a strong match. Likewise, it is not specifically described as gaming headphones, despite searches for the best USB-C charging gaming headphones for TV watching or a noise-canceling gaming headset for TV watching. Confirm both the TV’s Bluetooth support and the headset’s connection fit before treating it as a TV or gaming solution.
Side-by-Side: Which Should You Choose?
• Best for long stated talk time → Yealink BH70. Its listed maximum is up to 35 hours, compared with up to 13 hours for the Savi 7310.
• Best for DECT-focused call privacy → Plantronics Poly Savi 7310. It is designed for DECT Security Step C and includes 256-bit AES encryption.
• Best for Bluetooth connection flexibility → Yealink BH70. Its wireless connection is Bluetooth, and it includes a USB-C/A dongle.
• Best for desk-phone breadth → Plantronics Poly Savi 7310. It is described as compatible with more than 800 desk phones across the industry, with additional softphone support through Poly Hub.
• Best for call controls across meeting platforms → Yealink BH70. Its features include a flip-up mic mute, a physical mute button, a busy light, and stated support for platforms including Teams, Cisco, Zoom, and Google.
• Best for a single-ear work-call setup → Either, depending on connection needs. Both are mono-style headsets; the Savi 7310 uses DECT, while the BH70 uses Bluetooth.
• Best fit for TV watching → Neither is an obvious dedicated TV headphone. If choosing between these two, the BH70’s Bluetooth may be more convenient when a television supports Bluetooth audio, but its mono design remains a compromise for movies and shows.
I would choose the Yealink BH70 if I had to pick one of these for occasional TV watching, because Bluetooth gives it a more plausible route to a compatible television and its talk-time figure is longer. I would still verify the TV connection first: the BH70 is a mono work headset, not a stereo TV headphone. For sensitive desk-phone calls and long roaming range, I’d choose the Plantronics Poly Savi 7310 instead. My recommendation for TV watching is therefore the BH70 only when Bluetooth compatibility and mono audio are acceptable.
Neither is described as a dedicated stereo TV headphone. The BH70 uses Bluetooth, which may suit a Bluetooth-enabled TV, while the Savi 7310 is a DECT work headset. Check that your television supports the connection you plan to use.
The stated talk time is up to 35 hours for the BH70 and up to 13 hours for the Savi 7310. These are talk-time figures; they don’t establish how long either headset will last during TV playback.
The Savi 7310 has a noise-canceling microphone with Acoustic Fence technology. The BH70 has three microphones and noise-reduction processing intended to help isolate your voice. These descriptions focus on call microphones, not necessarily on blocking sound for the listener.
The BH70 is Bluetooth, but the provided details do not guarantee compatibility with a specific TV. The Savi 7310 uses DECT, and its listed strengths center on desk phones and softphones. Check your TV’s audio outputs and supported wireless connections before deciding.
