This year's Father's Day falls on Sunday, June 21, and those who are still stressing on how to make the stars of the day feel special need not fret. The key to making a dad happy is knowing what he likes and making sure he gets it. So for the occasion, it's all about knowing the man of the house. 

For the dad who is into tech, gadgets will likely make his day. One will never go wrong with an all-round smartwatch. Not only will this gizmo amp up his style, the all-inclusive wearable has great features that's all about productivity and convenience. 

Dad will surely love going to the office wearing an Apple Watch, which offers a wide range of models and designs. An Apple Watch Sport costs $349. The pricing will depend on the bands and material of the timepiece. Apple's site offers options to choose from. 

A Microsoft Surface Pro 3 ($799) will be great for the dad who carts in work whenever he can; but for him who simply loves to read whenever he feels like, a $99 Amazon eReader will hit the nail on the head. For the dad who always drives, a Zuna Drive smartphone case will keep his smartphone in sight. 

Father's Day for the music-loving dad will be awesome with either the Sengled Pulse Bluetooth, an LED light bulb with integrated JBL Bluetooth speakers, or a Sennheiser Momentum In-Ear Headphones for daddies who like to enjoy music by themselves or listen to their favorite songs on their way to work. 

Speaking of work, one can help daddy carry his work in style with a Bude Backpack from Knomo. This $169 pack is made of lightweight canvas and can house a 15-inch laptop. It is also made to resist dirt and water apart from making a working dad look sleek and stylish. 

Dads who are all about fun will enjoy the $499 Parrot Bebop drone with built-in HD camera that he can control using an Android or an iOS device. For the man whose idea of fun is Netflix, Hulu Plus, Amazon Instant Video, there the Amazon Fire Stick.
