Features

Active Noise Cancelling (ANC) Function

Feature Description

Reduces ambient noise using microphones and signal processing. Ideal for travel, commuting, or noisy environments where you want to focus on your audio.

About This Product

These headphones do not have active noise cancellation. They rely on passive noise isolation to reduce ambient noise. This means they won't block out as much noise as ANC headphones, but they also don't require batteries or complex circuitry.

Transparency Mode Function

Feature Description

Allows external sounds to be heard while wearing headphones. Useful for safety when walking in urban environments, or for having conversations without removing your headphones.

About This Product

Transparency mode is not available on this model. Users will not be able to hear external sounds without removing the headphones. This could be a drawback in situations where awareness of surroundings is important, such as walking near traffic.

Multipoint Pairing Function

Feature Description

Connects to two devices simultaneously. You can seamlessly switch between listening to music on your laptop and answering a call on your smartphone.

About This Product

Since these are wired headphones, multipoint pairing is not applicable. They can only connect to one device at a time via the 3.5mm jack. This simplifies the connection process but lacks the convenience of switching between multiple devices.

Customizable EQ Function

Feature Description

Allows users to adjust the sound profile of the headphones to their preferences. Fine-tune bass, treble, and mid-range frequencies to optimize the audio for different music genres or personal tastes.

About This Product

These headphones do not offer customizable EQ settings. The sound profile is fixed, which may not suit users who prefer to fine-tune their audio. However, the default sound is designed to be balanced and suitable for a variety of content.

Detachable Cable Function

Feature Description

The audio cable can be disconnected from the headphones. If the cable is damaged, it can be easily replaced without needing to repair or replace the entire unit.

About This Product

The cable is not detachable, which means that if the cable is damaged, it cannot be easily replaced without potentially needing to replace the entire unit. This could reduce the lifespan of the headphones if the cable is subjected to wear and tear.

Folding Design Function

Feature Description

The headphones can be folded for compact storage. Makes the headphones easier to transport in a bag or backpack when not in use.

About This Product

The folding design allows for compact storage, making these headphones easy to transport in a bag or backpack. This feature is particularly useful for travelers and students, ensuring that the headphones remain protected when not in use. The included carrying pouch further enhances portability.

Ranked #58 out of 100 products in Category

2.7

Overall Rating

These headphones are a budget-friendly option for kids, offering basic functionality and hearing protection. Durability may be a concern with extended use. Good for basic use cases like school and travel.

Sound Quality (Frequency Response)

3.5

Rating Criteria Explanation

The frequency response of headphones indicates the range of sound frequencies it can reproduce. Generally, headphones with a wider frequency range (e.g., 20Hz - 20kHz, which is the typical range of human hearing) can reproduce a more complete and balanced sound. Look for reviews and frequency response charts to understand how the headphones emphasize different parts of the spectrum (bass, mids, treble). A flat frequency response is often desired for accurate sound reproduction, while some headphones may boost bass for a more 'fun' sound. Consider your preferred music genres and listening habits when evaluating this aspect. For example, bass-heavy music benefits from headphones that accentuate lower frequencies, while classical music may sound better on headphones with a more balanced profile.

Rating Comments

The frequency response is standard (20Hz - 20kHz), providing adequate sound for general use. The two speakers deliver clear sound, suitable for music, online courses, and gaming. However, audiophiles may find the sound quality lacking in depth and detail.

Comfort and Fit

4.0

Rating Criteria Explanation

Comfort is paramount, especially for extended listening sessions. Over-ear headphones should have well-padded earcups that don't put too much pressure on your ears. The headband should also be comfortable and adjustable to accommodate different head sizes. Consider the materials used (e.g., leatherette, velour) as they can affect breathability and heat buildup. Also, think about the weight of the headphones; heavier headphones can become uncomfortable over time. Fit refers to how securely the headphones stay on your head. If you plan to use them during activities like jogging or working out, a snug and secure fit is crucial. Some headphones are designed with more clamping force for this purpose, but this can also impact comfort.

Rating Comments

The over-ear design and adjustable headband provide a comfortable fit for most children. The earcups are adequately padded, reducing pressure during extended use. The lightweight design ensures that the headphones don't feel too heavy on the head, enhancing comfort.

Noise Isolation/Cancellation

3.8

Rating Criteria Explanation

Noise isolation refers to the headphone's ability to physically block out external noise through its design and materials. Over-ear headphones generally provide better noise isolation than on-ear or in-ear models simply because they cover the entire ear. Noise cancellation, on the other hand, uses active electronic circuitry to reduce ambient noise. This is particularly useful in noisy environments like airplanes, trains, or busy offices. There are varying degrees of noise cancellation effectiveness. Some headphones offer adjustable noise cancellation levels, allowing you to tailor the amount of noise reduction to your specific environment. Consider whether you need passive isolation, active noise cancellation, or a combination of both based on where you plan to use the headphones most often.

Rating Comments

These headphones offer passive noise isolation, which helps to reduce ambient noise. This feature is useful in classrooms or during travel, allowing kids to focus on their audio. However, it's not as effective as active noise cancellation in very loud environments.

Bluetooth Codec Support

0.0

Rating Criteria Explanation

If you're using Bluetooth headphones, the audio codec used for wireless transmission significantly affects sound quality. SBC is the standard Bluetooth codec, but it's also the lowest quality. Higher-quality codecs like aptX, aptX HD, LDAC, and AAC offer better sound fidelity and lower latency. However, both your headphones and your audio source (e.g., smartphone, laptop) must support the same codec to take advantage of it. Check the specifications of both devices to ensure compatibility. For example, if you have an Android phone, aptX codecs are common, while AAC is more prevalent on Apple devices. LDAC offers the highest bitrate but requires compatible devices. Using a higher-quality codec can result in noticeably improved audio clarity and detail.

Rating Comments

Since these are wired headphones, Bluetooth codec support is not applicable. They connect via a 3.5mm jack, ensuring compatibility with a wide range of devices. This eliminates the need for Bluetooth pairing and reduces latency issues.

Battery Life and Charging

0.0

Rating Criteria Explanation

Battery life is a crucial consideration for wireless headphones, especially if you plan to use them for extended periods or while traveling. Look for headphones with a long battery life (e.g., 20+ hours) to avoid frequent charging. Also, consider the charging time; some headphones offer fast charging capabilities, providing several hours of playback with just a short charging session. Check if the headphones use a standard charging port (e.g., USB-C) for convenience. Some headphones also offer the option of wired listening, which can be useful when the battery is depleted. Knowing how long the headphones take to fully charge and how long they last on a single charge is very important to making an informed decision.

Rating Comments

As wired headphones, battery life and charging are not relevant. These headphones draw power directly from the connected device, ensuring uninterrupted listening without the need for batteries or charging.

Microphone Quality (for Calls/Conferencing)

3.5

Rating Criteria Explanation

If you plan to use your headphones for phone calls, video conferencing, or online gaming, microphone quality is essential. Look for headphones with a clear and noise-canceling microphone that can accurately capture your voice and minimize background noise. Some headphones have multiple microphones or advanced noise reduction algorithms to improve voice clarity. Read reviews or listen to microphone samples to assess the microphone performance in different environments. A good microphone ensures that you can communicate effectively without having to speak loudly or repeat yourself. The presence of a high-quality microphone can greatly enhance the overall communication experience when using the headphones for calls or online meetings.

Rating Comments

The built-in HD microphone allows for hands-free talking and clear communication during online courses and video calls. While it's adequate for basic use, the microphone quality may not be exceptional in noisy environments. It is suitable for general communication purposes.

Manufacturer Reliability and Warranty

3.0

Rating Criteria Explanation

The reputation of the manufacturer can be a good indicator of product quality and customer support. Established brands often have a track record of producing reliable products and providing good after-sales service. Check online reviews and forums to see what other customers have experienced with the brand and the specific headphone model you're considering. A good warranty can provide peace of mind, knowing that you're protected against defects or malfunctions. Pay attention to the warranty period and the terms and conditions. Some manufacturers offer extended warranties for an additional cost. A reputable manufacturer will stand behind their products and provide prompt and helpful support if you encounter any issues. Considering the manufacturer's reliability and warranty policies can help you make a more confident purchase.

Rating Comments

SIMOLIO is a brand committed to researching hearing needs and providing safe audio products. While not as well-known as some major brands, they offer customer support and a focus on hearing protection, adding to their reliability. The warranty information should be checked upon purchase.

Cost Performance

4.0

Rating Criteria Explanation

Ultimately, you need to balance the features and performance of the headphones with their price. Consider your budget and identify the features that are most important to you. Don't necessarily assume that the most expensive headphones are always the best. There are many excellent headphones available at different price points. Read reviews and compare specifications to find the headphones that offer the best value for your money. Consider factors such as sound quality, comfort, features, and durability when evaluating the overall cost-effectiveness of the headphones. A good cost-performance ratio ensures that you're getting the most for your investment.

Rating Comments

At $18.99, these headphones offer good value for the price. The combination of hearing protection, built-in mic, sharing jack, and foldable design make them a cost-effective option for parents seeking reliable headphones for their children.
