Dimension comparison
Design and Portability
Both the INSMY C12 and Soundcore Select 4 Go Bluetooth speakers are designed with portability in mind, but they cater to slightly different user preferences. The INSMY C12 features a compact round design that is small enough to fit in a beach bag, allowing for easy transportation. Weighing in as a lightweight option, it also includes a lanyard and detachable suction cup for versatile placement. In contrast, the Soundcore Select 4 Go is designed to be ultra-portable, featuring a lightweight structure complemented by a strap for easy carrying. It is also noted for its ability to float, which adds to its portability for water-based activities.
Sound Quality
When it comes to sound quality, the INSMY C12 offers immersive audio with its active deliver and extra passive radiator, delivering loud and clear sound even in noisy environments like showers. While the exact output power isn't specified, it is designed for a robust auditory experience. The Soundcore Select 4 Go, on the other hand, boasts a surprisingly punchy 5W output that ensures dynamic audio performance. Both speakers excel in providing quality sound, but the specific emphasis on bass and clarity in the INSMY C12 may appeal more to bass enthusiasts.
Waterproofing and Durability
The waterproofing features of both speakers are impressive, but they have slightly different specifications. The INSMY C12 is rated at IP67, meaning it can be fully submerged in up to 1 meter of water for about 30 minutes, making it suitable for extreme conditions. The Soundcore Select 4 Go also carries an IP67 rating but enhances its outdoor usability by being able to float, which can be beneficial for activities like swimming or boating. Both models are shockproof and built to withstand outdoor elements, but if floating capability is essential for your activities, the Soundcore Select 4 Go has the edge.
Battery Life
In terms of battery life, the Soundcore Select 4 Go outperforms the INSMY C12, providing an impressive 20 hours of playback on a single charge. This extended duration is ideal for all-day outings, ensuring your music continues without interruption. Meanwhile, the INSMY C12 offers a respectable 12 hours of playtime, which is still suitable for most casual use but falls short compared to its competitor. The difference in battery life—approximately 67% more for the Soundcore Select 4 Go—could be a deciding factor for those who prioritize longer listening sessions.
Price Point
When evaluating the price, the Soundcore Select 4 Go is priced at $24.99, making it about 17% cheaper than the INSMY C12, which retails for $26.99. This lower price point may attract budget-conscious buyers looking for quality without overspending. However, the slight premium for the INSMY C12 could be justified by its unique sound features and design elements. Ultimately, the choice may come down to how much value you place on specific features versus saving a few dollars.
Best Seller Rank
Sales performance can be an indicator of customer satisfaction and popularity. The Soundcore Select 4 Go holds a significantly higher bestseller rank of 257 compared to the INSMY C12's rank of 1324. This suggests that the Soundcore has a wider appeal and may be favored among consumers, possibly due to its combination of features, price, and sound quality. If you're inclined to trust popular opinion, the Soundcore Select 4 Go might be the more appealing option given its higher ranking.
User Experience
Both speakers aim to enhance the user experience, but they offer different functionalities. The INSMY C12 is equipped with a built-in microphone for hands-free calls, making it convenient for multitasking. Additionally, it supports TF card playback, allowing users to enjoy music without needing Bluetooth connectivity, which can be a useful feature in certain scenarios. The Soundcore Select 4 Go, however, supports True Wireless Stereo (TWS) pairing, enabling users to connect two speakers for a more immersive audio experience. This feature may appeal to users who want to enhance their listening environment, especially in outdoor settings.
Which should you buy?
Choosing between the INSMY C12 and the Soundcore Select 4 Go ultimately depends on your specific needs and preferences. If you prioritize battery life and a lower price, the Soundcore Select 4 Go, at $24.99, is a compelling choice with its 20-hour playback and floating capability. However, if sound quality, microphone functionality, and unique design features are more important to you, the INSMY C12 at $26.99 offers a robust alternative. Both speakers excel in portability and waterproofing, so you can't go wrong with either option based on the features that matter most to you.
