This significant difference may appeal to budget-conscious consumers looking for a portable audio solution. The lower price of the INSMY speaker does not compromise its features, making it an attractive option for those wanting quality sound without breaking the bank.

Sound Quality

In terms of sound quality, both speakers deliver impressive audio for their compact sizes. The INSMY Small Bluetooth Speaker features a 5W full-range speaker that provides rich audio and clear sound, claiming to create a surprisingly immersive experience for such a small device. On the other hand, the soundcore Select 4 Go also boasts a 5W output and emphasizes powerful and punchy sound. While both speakers excel in delivering quality audio, the choice may come down to personal preference for sound characteristics.

Battery Life

Battery life is another crucial factor for portable speakers. The soundcore Select 4 Go outshines the INSMY model with an impressive 20-hour playback time on a single charge. This extended battery life makes it suitable for long outdoor adventures or all-day gatherings. In contrast, the INSMY Small Bluetooth Speaker offers up to 10 hours of playback at 50% volume. For users who prioritize longer listening sessions, the soundcore Select 4 Go is the clear winner in this category.

The INSMY speaker is lightweight at just 100 grams and has a compact size, making it easy to carry in a handbag or pocket. Meanwhile, the soundcore Select 4 Go also features a lightweight design and includes a strap, enhancing its portability for various activities. However, the INSMY speaker’s smaller size may give it an edge for those seeking ultra-compact options.

Waterproof Rating

This makes it especially suitable for use in wet environments, such as while showering or at the beach.

While both products offer useful features, the INSMY model may appeal more to those interested in hands-free functionality.

Sales Rank

In terms of popularity, the soundcore Select 4 Go has a significantly higher sales rank, sitting at 253 compared to the INSMY Small Bluetooth Speaker's rank of 2062.
