Dimension comparison
Design and Build Quality
The INSMY C12 boasts an IP67 waterproof rating, allowing it to be fully submerged for up to 30 minutes, making it an excellent choice for outdoor activities. In contrast, the OontZ Angle 3 is rated as splashproof and can resist gentle water spray but cannot be submerged. This difference highlights the C12's superior durability for aquatic environments. The C12's compact design makes it portable, suitable for kayaking and shower use, while the OontZ Angle 3 has a unique triangular design that enhances sound quality, making it visually appealing and functional for home use.
Sound Quality
When it comes to audio, the OontZ Angle 3 delivers a higher quality sound with its dual precision acoustic stereo drivers and a proprietary passive bass radiator, providing clarity in mids and highs. It reaches a powerful 12 watts, ensuring loud, distortion-free playback. The INSMY C12, while also producing loud and clear sound, focuses on a bass-heavy experience with its active driver and passive radiator. However, its sound quality, although impressive for its size, may not match the clarity offered by the OontZ. Thus, audiophiles may prefer the OontZ for its refined sound profile.
Battery Life
The OontZ Angle 3 excels in battery performance, offering an impressive 24-hour playtime on a single charge, which is double the INSMY C12's 12-hour playtime. This extended battery life makes the OontZ more suitable for long outdoor events or extended listening sessions without the need to recharge frequently. The C12's shorter battery life may require more planning for longer outings, especially if consistent music playback is desired. The substantial difference in battery life could be a deciding factor for users who prioritize longevity in their speakers.
Connectivity
Both speakers offer reliable Bluetooth connectivity, but the OontZ Angle 3 shines with a remarkable 100-foot wireless range, allowing users to play music from a distance. This feature is particularly advantageous in outdoor settings where distance from the device may vary. The INSMY C12 supports Bluetooth but does not specify its range, making the OontZ a more appealing choice for those needing flexibility in their listening environments. Additionally, the C12 supports TF card playback, offering versatility for users who may not always have Bluetooth connectivity available.
Portability
The INSMY C12 is designed for portability, featuring a compact round design that fits easily into bags and can be attached to surfaces with its suction cup. This makes it ideal for beach trips or shower use. The OontZ Angle 3, while also portable, is slightly heavier at 10 oz and has a unique shape that may not be as easily stowed away. Users looking for a lightweight and versatile speaker that can be easily transported may find the INSMY C12 more suitable for their needs.
Price Point
In terms of price, the INSMY C12 is currently priced at $26.99, while the OontZ Angle 3 is slightly cheaper at $24.99, making it about 7% less expensive. While the price difference is minimal, it may influence budget-conscious buyers. Both speakers fall within a similar price range, making them competitive choices in the market. However, the added features and performance of each should be weighed against their respective costs to determine the best value for individual needs.
Popularity and Sales Rank
The OontZ Angle 3 holds a bestseller rank of 801, indicating its popularity among consumers. This rank suggests a strong market presence and customer satisfaction, which may instill confidence in potential buyers. The INSMY C12, with a sales rank of 1324, is also well-regarded but does not match the OontZ's popularity. For consumers who consider popularity and proven performance as key factors in their purchasing decisions, the OontZ Angle 3 may have the edge.
Which should you buy?
Ultimately, the choice between the INSMY C12 and the OontZ Angle 3 boils down to individual preferences and specific use cases. If you're looking for a waterproof speaker that excels in aquatic environments and is portable enough for various outdoor activities, the INSMY C12 is a solid choice. However, if sound quality, extended battery life, and greater Bluetooth range are your priorities, the OontZ Angle 3 offers compelling features that justify its selection. Both speakers provide excellent value within their price range, ensuring satisfaction for different listening needs.
