If you were planning to buy your old man a "World's Greatest Dad" mug for Father's Day, stop right now. You can do much better than that.

If your dad is into technology, there's a whole world of potential gift ideas out there, none of which will break the bank.

Here's our countdown of the best Father's Day gifts for any tech-loving dad.

1. Marshall Kilburn II

Is your dad still using an old transistor radio in his garden shed? Maybe it's time to drag him into the 21st century with a Bluetooth speaker, like the Marshall Kilburn II.

Both the design and cost of Bluetooth speakers vary considerably. However, the Kilburn II is great if you want a classic radio-feel that'll suit your dad's style.

He doesn't even need a music streaming subscription to enjoy it; there are lots of free music apps in the Google Play Store and Apple App Store, as well as plenty of radio options like TuneIn.

2. Amazon Fire TV Stick 4K

The Amazon Fire TV Stick 4K has rapidly grown to become one of the most popular TV streaming options. Their low cost combined with an impressive number of features (including the ability to sideload any Android apps) means they've become a must-have product among the cord-cutting crowd.

You can watch content from Netflix, Prime Video, Hulu Basic, STARZ, SHOWTIME, CBS, and more.

A few different Fire TV products are available---including the more expensive Fire TV Cube. However, for most users, the Fire TV Stick 4K will suffice. Even if you don't have a 4K TV, the more powerful specs of the 4K stick make it a better choice, especially given the price difference is minimal.

3. Plex Pass

If you have a lot of locally-saved video and music content, Plex is one of the best options for managing your collection, streaming it around your home, and accessing it remotely.

A Plex Pass introduces some useful features that are not available to free users. Most notably, you'll be able to watch and record live TV directly from the app (as long as you have an antenna). You also get offline access on mobile, and some premium music and photo features.

4. Amazon Kindle Paperwhite

No bookworm should be without an Amazon Kindle Paperwhite. These lightweight ereaders are the best-in-class, providing your dad with millions of titles at his fingertips.

Once again, a Kindle will also help your dad save some money. Kindle editions of books are consistently much cheaper than their paperback and hardback counterparts.

Just be aware that if your dad already has an extensive collection of ebooks from a non-Amazon source, there's a good chance he'll need to convert them into the AZW format before he can read them on a Kindle. The ebook management app Calibre can help.

Three Kindles are available---the All-New Kindle, the Kindle Paperwhite, and the Kindle Oasis. With 8GB or 32GB and 300ppi, the mid-range Paperwhite arguably offers the best value for money.

5. Audio-Technica AT-LP120-USB

Your dad might be the type of guy who prefers more "traditional" technology. If he's of a certain vintage, a vinyl turntable is worth considering. We like the Audio-Technica AT-LP120-USB; it offers a perfect mix of features for the price.

Don't worry; we're not suggesting you pick up a 1960s relic on eBay; turntable technology has moved on considerably in the last half-century.

Today's best turntables come equipped with Bluetooth, PC connectivity, and dozens of tweaks and settings, depending on the brand you buy.

6. Streaming Subscription

No one should be without a least one streaming subscription.

With the average cable TV bill in the United States now exceeding $100 per month, a streaming service will not only provide you with hundreds of hours of entertainment, but also save you some cash.

The problem? A recent explosion in the number of providers now means there are a lot of streaming services to choose from.

If your father is new to online streaming, we recommend going with Netflix. Despite the increasing competition, it still has the best library of content. You could also check out some niche apps like BritBox or Hulu Live, depending on his preferences.

7. Jabra Move

If your dad already has access to music streaming services, why not get him a pair of high-quality headphones? The difference in sound quality between cheap ear-buds and the best over-ear headphones is massive.

The very best headphones easily cost upwards of $500. For a more affordable solution, we like the Jabra Move. They are lightweight, sturdy, and offer eight hours of continuous playback.

8. Star Trek Blu-Ray Boxset

What do The IT Crowd, Doctor Who, Star Trek, Battlestar Galactica, and Red Dwarf all have in common?

Firstly, they're all TV shows adored by geeks. Secondly, they all have multiple series, making them perfect box sets to buy for a geeky dad on Father's Day.

Sure, lots of the series are available via video streaming services, but there's still something to be said for physical ownership of your media. We've gone for the Star Trek Blu-Ray Boxset as our pick, but make sure you let us know which are your favorite TV shows and movies for geeks in the comments.

9. Amazon Prime Subscription

Readers with shop-a-holic dads should consider an Amazon Prime subscription. It offers free two-day shipping on millions of items and even same-day shipping in lots of large cities.

But a Prime subscription is about more than the just shipping. Your dad will also get access to Prime Video, Prime Music, Audible channels, Prime Reading, Amazon Photos, and a whole lot more.

10. Best Dad Ever Mug

Okay, there's a lot of ideas listed above, so you should be able to find something your dad will like.

If nothing we've suggested has inspired you, you're beyond help. Perhaps you should get him that Best Dad Ever mug after all.
