INSMY C12 IP67 Waterproof Shower Bluetooth Speaker - Compact Loud

In this review the INSMY C12 is presented as a compact, water-ready speaker for people who want music at the shower, pool, or on short outdoor trips. The bottom line: it is ideal for anyone needing a truly waterproof, portable speaker with clear sound and long battery life. The reviewer found the IP67 waterproof rating, small but bass-forward design, and 12-hour playtime to be the strongest reasons to buy, while noting it is a small speaker so absolute maximum volume varies by taste.

Key Features

• IP67 waterproof: Can be fully immersed up to 1 meter for about 30 minutes, so it survives showers, pool splashes, and rainy days without worry.
• Shockproof design: Shock-absorbent materials and compact construction make it more durable for hiking, kayaking, and other outdoor activities.
• Big sound in a small body: An active driver plus a passive radiator deliver stronger bass and a surprisingly full sound from a very compact speaker.
• Long battery life: Built-in 1200mAh battery offers up to 12 hours of playtime, which is enough for a day at the beach or repeated shower sessions.
• Hands-free calls and accessories: Built-in microphone for calls and included lanyard plus detachable suction cup for mounting on tiles or mirrors.
• Multiple playback options: Bluetooth with lower latency and TF micro SD card support lets you play stored music without a paired device.

Who It's For

This speaker is best for shower users, swimmers, paddlers, and casual outdoor users who want a truly waterproof small speaker that can be attached to tiles or taken on a boat. The IP67 rating and included suction cup make it especially useful for bathroom and poolside listening.

Those looking for theater-level loudness, room-filling sound for large gatherings, or audiophile detail should look elsewhere; the C12 excels at portability, durability, and balanced sound for its size rather than extreme volume or ultra-high fidelity.
