Letyet 17oz Bluetooth Speaker Tumbler with LED Light - Travel Cup

Our review of the Letyet 17oz tumbler finds it best suited for people who want a travel cup that combines drink insulation with music and mood lighting. The single biggest reason to buy is the integrated Bluetooth speaker and detachable LED light built into the bottom, which turns a stainless steel vacuum insulated cup into a mini portable party or relaxing companion. The cup feels sturdy, holds a practical 17oz volume for coffee or cold drinks, and the double-layer powder-coated finish gives it grip and a pleasant look while the lid and straw make it convenient for sipping on the go.

Key Features

• Bluetooth speaker: The built-in speaker at the cup bottom provides hands-free audio playback so you can enjoy music while you drink without carrying a separate device.
• Detachable LED light: The removable LED light adds ambient illumination and can be used independently to create atmosphere at night or during outdoor gatherings.
• 17oz capacity: The 17OZ size is substantial enough for a large coffee or water while remaining compact enough for most cup holders and backpacks.
• Stainless steel vacuum insulation: Double-wall insulation helps keep beverages hot or cold longer than a single-wall cup, making it practical for daily use.
• Double-layer powder coat: The powder-coated finish improves grip, resists minor scratches, and gives a clean, colorful appearance in blue.
• Included lid and straw: The lid and straw combination reduces spills and makes sipping easy while commuting or working at a desk.

Who It's For

This tumbler fits people who want a multiuse drink container that doubles as a small speaker and light source, such as commuters who enjoy podcasts, students in dorm rooms, or anyone who likes to take music and ambient light to picnics or small gatherings. The 17oz capacity and vacuum insulation suit those who want a single cup for coffee, tea, or cold beverages throughout the day.

Those who need professional-grade audio or extremely long battery life should look elsewhere, since the speaker is designed for convenience and portability rather than high-fidelity sound. If you prefer a pure insulated bottle without electronics, a plain stainless steel tumbler would be a simpler, electronics-free alternative.
