The Sennheiser Momentum 2 earphones retail for $125, but Walmart has slashed $25.05 off its regular price tag just in time for the holidays.

Amazon's Fire TV box is the perfect gift for the television fanatic in your life.  

Shoppers who splurge on the set-top box can access popular games and streaming apps, like Hulu, Netflix and YouTube. Meanwhile Prime members get unlimited access to Amazon's original programming and can watch TV on specialty channels like Starz and Showtime. 

Parental controls, 4K compatibility and voice search support via Alexa Voice, Amazon's digital assistant, help the Fire stand out among the competition. 

Amazon Kindle: $79.99

The Amazon Kindle isn't as fancy as its higher-priced siblings — the PaperWhite ($119) and the Voyage ($199.99) — but it's still a great e-reader. The glare-free touchscreen display is easy to read from, and a fully charged battery lasts up to four weeks. Plus it's lightweight — clocking in at 161 grams — which makes it easy to carry around. 

Prime membership gives readers an unlimited number of books to read while the Kindle's complementary Goodreads integration makes it easy to connect and share thoughts and comments with other book lovers. 

Google Chromecast Ultra: $69

Sit back and relax this season with help from Google's easy-to-use Chromecast Ultra. 

The dongle allows owners to stream 4K and ultra high-definition videos from phones, tablets or streaming apps — like Netflix, CraveTV and YouTube — straight to their TV. It also opens up access to Chromecast-specific content from sites like Google Play

It also comes with an Ethernet adapter, which can be plugged into any router or modem for faster connections. If the Ultra's retail price is a little too steep, opt for Google's standard version that goes for $34.86, but doesn't include Ethernet or high-end streaming options.
