With its stainless steel build, the $99 Beats EP may be the best value in the Beats line. It comes in black, white, red and blue.
The $99 JBL Flip 4 is also waterproof and delivers similarly great sound.
The ideal gift for someone starting high school or college is a new pair of wireless headphones -- and there are now plenty of great choices in this under-$100 range. The Plantronics BackBeat 500 is one of our recent favorites, and it costs just $80.
The $65 Skullcandy Grind Wireless headphones are a good value for the price, too.
If you're buying for a runner or an athlete, the sporty BackBeat Fit wireless headphones may be just the ticket.
Jabra Halo Smart is a wireless "neckband" model. Its stereo earbuds magnetically hold together around the neck when not in use.
If your gifting budget is limited to around $60, the Sony MDR-XB50BS wireless in-ear headphones are a worthy choice.
Moving from wireless to wired headphones: The Sony MDR-7506 headphones are invariably older than the student you're buying them for -- they first debuted in 1991 -- but they're also the best-sounding headphones you can get for under $100.
This in-ear headphone is an older model, but it delivers solid sound -- and the comfy eartips will keep the buds in place during workouts.
If you're buying for someone who cares more about sound quality than familiar brands, consider the 1More Triple Driver. It's one of the best sounding in-ear headphones under $100.
The $99 Wonderboom is the latest wireless speaker from Ultimate Ears. It sounds great, and even floats -- making it the perfect speaker for summers around the pool.
With its springy coiled design, the Urbanears Stadion is a fresh take on a Bluetooth sports headphone for less than $100.
The Wonderboom's predecessor, the UE Roll 2, is also fully water-resistant -- and can be found for as little as $55.
The Flip 4's predecessor, the Flip 3, is still pretty great, and you can find it on sale for closer to $80.
At just $80, the Amazon Fire HD 8 is the best ultracheap tablet you can buy -- and a pretty great gift to boot.
The older BackBeat Sense wireless headphones have also dipped just south of the $100 mark.
Amazingly, Amazon's Kindle Paperwhite e-reader is actually more expensive than the Fire tablet. But this $119 unit is often discounted to $99. It's a good choice for bookworms who enjoy distraction-free reading.
Turning to video streaming: There are plenty of Roku models at $50 or less. But in the $100 range you'll find the Roku Premiere+. It's worth the extra cash if you're buying for someone who has a 4K TV with high dynamic range (HDR) video compatibility. But even if they don't, they'll like the Wi-Fi remote (no pointing needed) with a headphone jack for private listening.
The best alternative to Roku at this price point is the Amazon Fire TV. The core Fire TV bundle is now $90, the antenna bundle is $100 and the gaming edition bundle (with gamepad) is down to $130.
Young students are obsessed with their smartphones. And the Chromecast Ultra lets them beam most video apps (except for Amazon prime) from the phone to a TV, with 4K and HDR compatibility.
If you're buying for someone who spends all day on a Mac or Windows PC, a top-notch mouse like the Logitech MX Master is just the ticket.
The MX Anywhere 2 mouse is basically a downsized, portable version of the MX Master.
If your giftee is budding globetrotter, the Mophie PowerStation Plus is a good travel companion. The $60 external battery charger has an integrated Lightning cable with a micro USB adapter, so it can juice up most mobile devices.
Is your student moving into a new place? Get it smart home-ready with the Philips Hue White LED Starter Kit. The Alexa-compatible lighting kit includes two dimmable bulbs and a control bridge.
Does your student have a recent Samsung Galaxy phone? The latest Gear VR headset will turn it into a full-fledged virtual reality headset, with a cool new controller to boot.
The same goes for owners of Google's new phones. The $79 Daydream View turns the Pixel and Pixel XL into VR viewers -- and it includes a small controller as well.
Pioneer's Rayz Rally is a compact plug-and-play Lightning speaker for your iPhone or iOS device that doesn't require charging. It works best as a speakerphone but also can be used for music and boosting the sound during video playback.
If $100 is outside your budget, don't worry: We have a whole separate list of great back-to-school gift ideas for under $50, too.
