Controllers that attach directly to smartphones go by many names — telescopic, clamp-style, stretch controllers, and more. There are also cheap clip-on button attachments, like the discontinued GameSir F7 Flaw. But the market and most players have clearly settled on telescopic controllers as the best option. With one or two exceptions, this is the standard. Original article: https://www.hlplanet.com/telescopic-controllers-list/
Telescopic controllers expand horizontally to hold a smartphone in the middle, transforming it into something like a Nintendo Switch. The phone slides into the center, while the controller grips both sides. Most connect directly via USB-C or Lightning, which means:
No pairing fuss — just plug and play.
Low latency — far better than Bluetooth, especially for cloud gaming or competitive titles.
Comfortable design — shaped like a traditional console controller, making long sessions easier on the hands.
Pass-through charging — so you can play and charge at the same time.
Unlike Bluetooth pads (which can introduce lag) or cheap grips (which just add buttons on top of the touchscreen), telescopic controllers feel like a real console experience. They’re stable, ergonomic, and responsive. For people playing Xbox Cloud Gaming, PlayStation Remote Play, or emulators, the difference is night and day.
Backbone and Razer dominate the marketing space — you’ll see their names everywhere. And yes, they make very good controllers. But they’re also expensive. Meanwhile, brands like GameSir and EasySMX are pushing harder in 2025, offering hardware that’s just as good (if not better) for much less money.
What makes them stand out?
Hall Effect sticks and triggers (longer lifespan, no drift)
Extra features like back buttons, gyroscope, rumble, or even cooling fans
Lower latency and wider compatibility across Android, iOS, Switch, and even PC
Not all telescopic controllers work everywhere. Some are USB-C only, others Lightning, and some add Bluetooth fallback for extra flexibility. A few even double as controllers for Nintendo Switch or PC — handy if you don’t want to buy a second pad for couch co-op.
Here’s a quick look at the strongest options, without drowning in specs:
Backbone One (Gen 2) — The most polished experience, with companion app, official Xbox/PlayStation versions, and premium feel. Best for cloud gaming and casual players who want something that “just works.”
Razer Kishi V2 / V2 Pro — Excellent ergonomics and clicky buttons. The Pro adds haptics and a headphone jack. Best for serious gamers using Game Pass or GeForce NOW.
GameSir G8 Plus — Feature-packed at a mid-tier price. Hall Effect sticks, gyroscope, back buttons, and Bluetooth for iOS or Switch. Great for emulation fans or anyone who wants maximum versatility.
EasySMX M15 / M10 — Affordable yet premium, with Hall Effect hardware and back buttons. Strong choice for people who want performance without paying Razer/Backbone prices.
GameSir X3 Pro — A niche pick, but notable because it includes a built-in cooling fan — useful for demanding games that heat up your phone.
👉 Bottom line: If you want polish and branding, Backbone and Razer are still excellent. But if you care about durability, features, and price, GameSir and EasySMX are leading the way in 2025.
