Features

Waterproof Function

Feature Description

A function that protects the speaker from water splashes and rain. You can use it without worry at the beach, by the pool, or in the bathroom. Enjoy music anywhere without worrying about water damage.

About This Product

IPX7 waterproof rating allows the speaker to be fully submerged in water up to 3 feet for 30 minutes, making it perfect for use in the shower, at the beach, or by the pool. Enjoy worry-free listening in wet environments.

Built-in Microphone Function

Feature Description

A function that allows hands-free calling when connected to a smartphone. You can answer calls directly through the speaker while doing housework or working. Convenient for hands-free communication.

About This Product

This speaker does not have a built-in microphone, so you cannot use it for hands-free calling or voice assistant control. This limits its functionality compared to speakers with this feature.

External Device Charging Function

Feature Description

A function that allows charging smartphones and other devices using the speaker's battery. Useful as a backup battery for your smartphone when you are outdoors. Prevents battery drain when away from power sources.

About This Product

This speaker does not support external device charging, so you cannot use it as a power bank for your smartphone or other devices. This reduces its utility for outdoor activities where power sources are limited.

Stereo Pairing Function

Feature Description

A function that allows connecting two identical speakers for stereo playback. You can enjoy a wider soundstage and more powerful sound by separating the left and right channels. Enhances the immersive experience when watching movies or listening to music.

About This Product

You can pair two OontZ Ultra speakers together for stereo playback, creating a wider soundstage and more immersive listening experience. This feature enhances the audio quality for music and movies.

Preset Equalizer Function

Feature Description

A function that allows selecting sound modes optimized for different music genres. You can easily switch to the ideal sound settings for pop, rock, or classical music. Enjoy music with sound quality tailored to each genre.

About This Product

This speaker does not have preset equalizer functions, so you cannot easily switch between sound modes optimized for different music genres. This limits customization of the audio output.

Voice Assistant Activation Function

Feature Description

A function that allows activating voice assistants like Siri or Google Assistant. You can control music playback, check the weather, and perform other tasks hands-free. Provides smart control without touching your smartphone.

About This Product

This speaker does not support voice assistant activation, so you cannot use voice commands to control music playback or access other smart features. This reduces its convenience compared to speakers with voice control.

SHOPSTAFF Rating Score

#31

Ranked #31 out of 99 products in Category

3.8

Overall Rating

The OontZ Ultra Dual offers good sound and stereo pairing at an affordable price. However, it lacks advanced features and may not suit audiophiles. It's suitable for casual listening and outdoor use.

Sound Quality (Frequency Response, Clarity)

3.5

Rating Criteria Explanation

The most crucial aspect of any speaker is its sound quality. Consider the frequency response range – a wider range (e.g., 20Hz - 20kHz) generally indicates the speaker can reproduce a broader spectrum of sounds, from deep bass to crisp highs. Clarity refers to how well you can distinguish individual instruments and vocals within a song. A speaker with good clarity will sound detailed and defined, while a speaker with poor clarity might sound muddy or muffled. Listen for distortion at higher volumes, which indicates the speaker is struggling to reproduce the sound accurately. Read reviews and, if possible, listen to the speaker in person or watch sound tests online before purchasing. Pay attention to descriptions of bass response (is it boomy or tight?), mid-range clarity (are vocals clear and present?), and treble detail (are high frequencies crisp without being harsh?).

Rating Comments

Offers clear audio and decent bass for its size, but may lack the depth and clarity of higher-end models. Good for casual listening but not for critical audiophiles. Distortion is minimal at moderate volumes.

Battery Life

4.0

Rating Criteria Explanation

A portable speaker is only as good as its battery life. Consider how long you'll typically use the speaker between charges. If you plan on using it for long periods outdoors, like camping or at the beach, a longer battery life is essential. Pay attention to the stated battery life and read reviews to see if it matches real-world performance. Battery life is often specified at a moderate volume level; playing music at higher volumes will drain the battery faster. Also, consider the charging time. A speaker that takes a very long time to charge can be inconvenient. Some speakers also offer power bank functionality, allowing you to charge your phone or other devices, which can be a valuable feature.

Rating Comments

Provides a solid 20 hours of playtime, suitable for extended outdoor use. Charging time is quite long at 20 hours. This could be inconvenient for users needing a quick recharge.

Durability and Water Resistance

4.5

Rating Criteria Explanation

Since it's a portable speaker, durability is key. Look for speakers with rugged designs that can withstand bumps, drops, and exposure to the elements. Water resistance is also important, especially if you plan on using the speaker near water (pool, beach, shower). IP ratings (e.g., IPX5, IPX7) indicate the level of water resistance. IPX5 means the speaker can withstand splashes of water, while IPX7 means it can be submerged in water for a short period. Consider the materials used in construction. Speakers with rubberized housings or reinforced corners are generally more durable. Read reviews to see how well the speaker holds up over time and in different conditions.

Rating Comments

IPX7 waterproof rating ensures protection from water submersion, making it ideal for beach and poolside use. The build quality is durable enough to withstand bumps and drops.

Bluetooth Connectivity and Range

4.0

Rating Criteria Explanation

Reliable Bluetooth connectivity is essential for a seamless listening experience. Look for speakers that support Bluetooth 5.0 or later, as these versions offer improved range, stability, and power efficiency. The stated Bluetooth range is also important, especially if you plan on moving around while using the speaker. A range of 30 feet or more is generally sufficient. Consider whether the speaker supports multi-point pairing, which allows you to connect to two devices simultaneously. This can be convenient if you want to switch between playing music from your phone and your tablet. Check reviews to see if users have experienced any connectivity issues, such as dropouts or difficulty pairing.

Rating Comments

Bluetooth 5.0 offers a stable connection with a range of 100ft, allowing for uninterrupted music streaming. Multi-point pairing is not explicitly mentioned, which could be a limitation.

Portability and Size

4.0

Rating Criteria Explanation

The ideal size and weight of a portable Bluetooth speaker depend on how you plan to use it. If you want something that's easy to carry in a backpack or purse, a smaller and lighter speaker is preferable. However, smaller speakers often have limitations in sound quality and battery life. Consider the overall dimensions and weight of the speaker, and whether it has a convenient carrying handle or strap. If you plan on using the speaker primarily at home, a slightly larger and heavier model might be acceptable, as it can offer better sound quality. Think about where you'll be using it most often.

Rating Comments

The speaker is portable and easy to carry, though not the smallest option available. Its size is a good balance between portability and sound quality, suitable for various environments.

Extra Features (Microphone, AUX Input, USB Charging)

2.5

Rating Criteria Explanation

Consider any extra features that might be useful to you. Some speakers have built-in microphones for taking calls or using voice assistants like Siri or Google Assistant. An AUX input allows you to connect devices that don't have Bluetooth, such as older MP3 players. USB charging ports can be used to charge your phone or other devices. Some speakers also have FM radio functionality or support for playing music from USB drives or microSD cards. Evaluate which features are important to you and choose a speaker that offers the right combination of features.

Rating Comments

Lacks a built-in microphone, AUX input, and USB charging. The absence of these features limits its versatility compared to other portable speakers. No voice assistant support.

Manufacturer Reliability and Warranty

4.0

Rating Criteria Explanation

The reliability of the manufacturer is a significant factor in the longevity and overall satisfaction with your Bluetooth speaker. Established brands with a good reputation are generally a safer bet, as they are more likely to offer reliable products and good customer support. Research the manufacturer's history and read reviews to see what other customers have experienced. A solid warranty is also crucial. A longer warranty period indicates that the manufacturer has confidence in the quality of their product. Check the terms of the warranty to understand what is covered and what is not. A good warranty can provide peace of mind and protect you from unexpected repair costs.

Rating Comments

Cambridge Soundworks is a reputable brand with a history of producing audio equipment. The limited warranty provides some assurance, but a longer warranty would be preferable.

Cost Performance

4.0

Rating Criteria Explanation

Ultimately, you need to consider the cost performance of the Bluetooth speaker. This means evaluating the features and performance of the speaker relative to its price. A more expensive speaker might offer better sound quality, battery life, and durability, but it might not be worth the extra cost if you don't need those features. Read reviews and compare different models to see which offers the best value for your money. Don't automatically assume that the most expensive speaker is the best choice. Consider your budget and prioritize the features that are most important to you.

Rating Comments

Offers good value for its price, providing a balance of sound quality, durability, and portability. It's a worthwhile option for budget-conscious consumers seeking a reliable portable speaker.
