Yealink T8 & T7 Series Review: All 8 Models Compared

TL;DR – Summarise this page with AI

Yealink’s T8 and T7 Series are the current generation of its desk phone line-up: the T8 Series sits at the top as the flagship range, and the T7 Series covers the mid-range professional desk phone most offices actually buy in volume. Between the two series there are eight models, and the differences aren’t always obvious from the model number alone. This review goes through all eight – what each one actually offers, where the real differences are, and which one makes sense depending on how someone actually uses their desk phone.

All eight models share the same underlying design language and a few core technologies worth calling out once rather than repeating eight times: a 3W speaker tuned for “professional-grade loudness,” Yealink’s noise-filtering acoustics (branded “Smart Noise Filtering” on the T7 Series and “AI Noise Cancellation” on the T8 Series) paired with what Yealink calls an Acoustic Shield to cut background noise, a choice of dark or light UI themes, support for Yealink’s colour-screen expansion modules, and the same three-layer “Three Rings of Security” architecture (device integrity, network protection via 802.1X/WPA3, and transmission security via TLS 1.3 and SRTP) across every model. Where a model doesn’t publish a spec – some SIP line-count and exact port details weren’t listed on Yealink’s own product pages for several of these models – this review doesn’t guess at a number.

T8 Series: The Flagship Range

The T8 Series is Yealink’s top tier – larger screens, built-in WiFi 6 and Bluetooth 5.0 across the board, and (on the T88) a full Android operating system rather than a traditional embedded phone OS. This is the range to look at for executive desks, reception areas that double as a showcase of the office’s phone system, or anyone who wants the expansion-module ecosystem with the most headroom.

SIP-T88

The T88 is the only phone in either series running a full Android 13 operating system, and it shows: a 7-inch capacitive touchscreen at 1024×600 (noticeably sharper than the other 7-inch screens in the line-up, which top out at 800×480), a tilt angle that adjusts up to 30 degrees, and support for up to three EXP55 expansion modules – more than any other model reviewed here. It’s also the only phone with an optional (and on the T88W Pro and T88V Pro, standard) Yealink BTH88 Bluetooth handset, letting someone genuinely cordless-handset a desk phone call rather than being tied to the base unit. Built-in Bluetooth 5.0 and WiFi 6.0 are both included. For security, it runs the same Trusted Execution Environment and Three Rings of Security model as the rest of the range, with TLS 1.3, WPA3 and 802.1X all supported.

Best for: executives, reception desks, or anyone who wants the expansion-module ceiling raised as high as Yealink currently goes, plus the option of a cordless handset.

SIP-T87W

The T87W carries the same 7-inch touchscreen form factor as the T88 but at a more modest 800×480 resolution, on a traditional embedded firmware rather than Android – a meaningfully simpler (and likely more affordable) way into the T8 Series’ screen size and expansion-module support. It keeps built-in Bluetooth 5.0 with close-to-pair headset support, WiFi 6.0, USB headset and EHS support, and adds dedicated one-touch speed-dial buttons, a hotline key, and physical mute/DND buttons – small details that matter in a busy front-desk or shared-line setup. Yealink also notes PCR (post-consumer recycled) materials and green packaging for this model specifically.

Best for: front-desk and shared-line environments where physical one-touch buttons and a large screen matter more than an Android-level interface.

SIP-T85W

The T85W is the compact option in the T8 Series: a 5.5-inch display at 960×480 rather than the 7-inch screens on the T88 and T87W, in what Yealink describes as a slimmer body with an “invisible hinge” design. It keeps the full T8 feature set otherwise – built-in Bluetooth 5.0 with close-to-pair, WiFi 6.0, colour-screen expansion module support, USB headset and EHS – and adds a dedicated emergency button and antimicrobial casing materials, which point this model specifically at healthcare and similar shared-equipment environments.

Best for: desks that don’t need a 7-inch screen but still want T8-level wireless and expansion support – and specifically healthcare or clinical settings, given the antimicrobial materials and emergency button.

T7 Series: The Professional Range

The T7 Series is where most general office desks land – five models split by screen size (7-inch, 4.3-inch, or 2.8-inch) and, within the 4.3-inch and 2.8-inch sizes, a choice between a “W” variant with built-in WiFi 6.0 and Bluetooth 5.0, or a “U” variant without wireless built in. The T77U is the exception: it has the largest screen in the T7 Series but leads with USB-A and USB-C ports rather than the built-in WiFi/Bluetooth pairing the W models use.

SIP-T77U

The T77U takes the 7-inch, 800×480 touchscreen from the T87W and pairs it with both USB-A and USB-C ports – a connectivity-first take on the same screen size, with a two-angle adjustable stand (versus the T87W’s single angle) and the same colour-screen expansion module support. It’s the clearest “big screen without going into the T8 Series” option in the line-up.

Best for: anyone who wants the 7-inch T8-style screen and expansion-module support, in a wired-first setup, without paying for T8 Series positioning.

SIP-T74W

The T74W is the mid-size, wireless-equipped option: a 4.3-inch, 480×272 touchscreen with built-in WiFi 6.0 and Bluetooth 5.0 (with close-to-pair), PoE support, USB headset and EHS compatibility, and colour-screen expansion module support. This is the “no-compromise standard desk phone” of the range for anyone who wants wireless flexibility without stepping up to a 7-inch screen.

Best for: general office desks that want WiFi/Bluetooth flexibility (hot-desking, flexible desk layouts) without needing a large screen.

SIP-T74U

The T74U carries the same 4.3-inch, 480×272 screen and two-angle stand as the T74W, in a wired-first configuration – Yealink’s own page for this model doesn’t list the built-in WiFi/Bluetooth pairing the W variant leads with, which tracks with Yealink’s usual U/W naming split. For a desk with a fixed Ethernet drop and no need for wireless peripherals, it’s the straightforward version of the same screen and build.

Best for: fixed desks on wired Ethernet where WiFi and Bluetooth aren’t needed.

SIP-T73W

The T73W steps down to a 2.8-inch, 320×240 colour display, while keeping built-in WiFi 6.0 and Bluetooth 5.0 with close-to-pair, USB headset and EHS support, and colour-screen expansion module compatibility. It’s effectively the T74W’s feature set in a smaller, simpler screen footprint – the wireless-equipped entry point into the T7 Series.

Best for: standard desks that want WiFi/Bluetooth flexibility but don’t need (or want to pay for) a larger screen.

SIP-T73U

The T73U is the simplest model in either series reviewed here: the same 2.8-inch, 320×240 display as the T73W, in a wired configuration without the built-in wireless. It keeps the same noise-filtering acoustics, Three Rings of Security architecture, and accessibility mode as every other model in the line-up. For desks that just need a reliable, no-frills IP phone, this is that phone.

Best for: standard wired desks where a compact screen and core calling features are all that’s needed.
