Letyet 17oz Bluetooth Speaker Tumbler - Insulated Travel Cup

In this review of the Letyet 17oz tumbler cup, the bottom line is simple: this is a travel-friendly insulated cup for people who want a functional drink container that doubles as a party-ready speaker. The reviewer found the main draw to be the integrated Bluetooth speaker and detachable LED light that flash with music, which makes sipping a beverage more entertaining without sacrificing utility. It is best suited to commuters, outdoor loungers, or anyone who wants a 17oz insulated cup that fits a car cup holder and keeps drinks hot or cold for hours.

Key Features

• Bluetooth speaker: The removable wireless speaker in the base streams audio and syncs with the LED light to flash with the rhythm of your music for a lively listening experience.
• Vacuum insulation: Double-walled vacuum construction helps keep hot drinks hot and cold drinks cold for extended periods while preventing heat transfer to the outer wall.
• Durable stainless steel: Constructed from two layers of 18/8 food grade stainless steel with an electropolished interior to resist rust and maintain flavor neutrality.
• Spill-resistant lid: Comes with a BPA-free sliding lid and reusable straw so the tumbler is neat to use on the go and easy to drink from.
• Tapered, car-friendly shape: The tapered design is made to fit most car cup holders and measures about 7.8 in tall and 3.7 in wide for convenient transport.
• Powder-coated finish: The double-layer powder coating provides a secure grip, sweat-free exterior, and a blue color that resists slips and marks.

Who It's For

The Letyet 17oz tumbler is ideal for people who want a single cup that combines drink insulation with casual entertainment, such as commuters who enjoy podcasts or playlists while traveling, or friends who want portable ambient lighting and sound at picnics. Its 17oz capacity suits those who prefer a moderate serving of coffee, tea, or cold drinks without frequent refills.

It may not be the best choice for audiophiles seeking high-fidelity sound or for those who need an ultra-compact mug for tight bag storage. If you need a vacuum flask with an extremely narrow mouth for sipping or a cup without electronics in the base, consider a plain insulated tumbler instead.
