Now that it's $100 off, reaching the price of $249.99 (originally $349.99) after the on-page coupon, it's at its lowest price ever, according to price-tracking tools. While you might've never heard of the brand before, I can attest that this speaker is quality, and now, it's a bargain for its price. Ikarao Shell S1 Smart Karaoke Speaker Battery Life: 9 hours, Connectivity: USB, AUX In/Out, HDMI, Wifi, OTG, and Bluetooth V5.4. $349.99 at Amazon Get Deal Get Deal $349.99 at Amazon It bewilders me why no company before thought of doing what Ikarao has done with the Shell S1: Combine a touchscreen tablet, two Bluetooth microphones, and powerful sound to a small portable speaker. None of those things are new technologies, yet it took until Ikarao thought of it to make it happen. The Shell S1 is their newest and most affordable karaoke speaker. And it's loud enough to host a house party with its 104dB stereo speaker (it fills my whole 1,300 square foot home with sound loud enough to have a party). The two wireless microphones have a 20-hour rechargeable battery life while the speaker itself lasts about nine hours if you're using the screen. The screen is a 10.1-inch touchscreen tablet that lets you control the music. It comes with an integrated Spotify app but unfortunately no YouTube app (it does have a direct link to it using a web browser).You can hook up the speaker to a TV to have more people sing along with you, but you'll need to hook up an HDMI cable. There is a casting option but it's done through a third-party app that you need to download. It's not as easy as AirPlay or connecting an HDMI cable. If you're looking for a reliable and compact karaoke machine that you can hook up to your TV and play for hours, the Shell S1 at $250 is the best you can get right now.
