No, headphones need an amp first: if you want quiet practice, buy a compact guitar headphone amp. An adapter only changes plug size.

Short answer: no. You cannot plug normal headphones directly into an electric guitar and expect a usable sound. The guitar needs a headphone amp, practice amp with headphone output, audio interface, or multi-effects unit between the guitar and the headphones.
What to buy instead
If you came here because you want to practice quietly tonight, buy a compact guitar headphone amp first. Compare Fender Mustang Micro Plus if you want more features, or VOX amPlug 3 if you want the simplest plug-in option.

Why headphones do not work straight into a guitar
An electric guitar sends a weak instrument-level signal. Headphones need a headphone-level signal. A headphone amp or regular amp does the missing job: it amplifies the guitar, shapes the tone, and gives your headphones something usable to play back.
A passive adapter does not solve that problem by itself. A 1/4 inch headphone adapter is useful only after you already have a headphone output on an amp, interface, or headphone amp.

When you do need an adapter
Adapters are still useful, but only for matching plug sizes. If your amp has a 1/4 inch headphone jack and your headphones have a 3.5 mm plug, then you need an adapter. The adapter does not replace the amp.

My recommendation
If you are a beginner and the goal is quiet practice, do not start with adapters or recording gear. Start with a compact headphone amp. It is the simplest product category that directly solves the problem.
