Wireless gaming keyboards remove cable clutter, but they vary more in key feel and controls than the word “wireless” suggests. These three Logitech TKL models all support a 2.4 GHz LIGHTSPEED connection, Bluetooth and USB. The choice is therefore mostly about keyboard height, media controls and what you are prepared to spend.
The three to compare
| Model | Key profile | Media controls | Best fit |
|---|---|---|---|
| G515 LIGHTSPEED TKL | Low-profile | Function shortcuts | Slimmer, simpler wireless setup |
| PRO X TKL LIGHTSPEED | Standard mechanical | Media keys and volume roller | Conventional key height for gaming |
| G915 X LIGHTSPEED TKL | Low-profile | Media keys and volume roller | Slim build with PBT keycaps and more controls |
All three are tenkeyless, so none has a number pad. If a number pad is essential, these specific models are the wrong shortlist.
Start with the G515 if you want slim and simple
The G515’s low-profile GL switches make it visibly thinner than a conventional mechanical TKL board. That is useful if you want a flatter hand position and a cleaner desk. It still retains the function row and arrow keys. The trade-off is a leaner set of dedicated controls than the other two boards here; it does not have their prominent volume roller.
Logitech G515 LIGHTSPEED TKL

Layout: Tenkeyless
Connection: LIGHTSPEED 2.4 GHz, Bluetooth, USB
Switches: Low-profile GL mechanical
- Wireless desk setup
- Low-profile keys
- Room for mouse movement
- You want a number pad
- You want adjustable magnetic actuation
Choose the PRO X TKL for a conventional key height
The PRO X TKL looks and feels like the more traditional mechanical keyboard in this group. Logitech offers GX mechanical switch variants, while the TKL layout makes room for mouse movement. It adds dedicated media controls and a volume roller. If you already know you prefer taller keycaps and travel, this is the more relevant comparison against the low-profile G515 than a raw spec sheet alone.

- Compact competition-style layout

Consider the G915 X TKL for low profile plus controls
The G915 X LIGHTSPEED TKL combines a slim chassis with a media roller, dedicated media keys and double-shot PBT keycaps. It is the most feature-rich low-profile pick of these three. Those additions matter most if you use the same keyboard for games, media and everyday work. If you only want wireless TKL gaming, compare its current price to the G515 before choosing it.

Which one would we shortlist first?
Start with the G515 for a lower-profile wireless board without paying for extra controls. Choose the PRO X TKL if you prefer full-height mechanical keys. The G915 X TKL is the one to inspect when you want both a slim build and hardware media controls. Check the exact switch and layout variant in each Amazon listing; stock and prices can move independently of the product names.
