Cleer Ally Plus True Wireless Earbuds: Immersive Sound with Advanced Noise Cancellation
Update on Feb. 9, 2025, 5:54 p.m.
The modern world is a noisy place. From the rumbling of traffic to the chatter of crowds, we’re constantly bombarded with sounds that can be distracting, stressful, and even harmful to our hearing. It’s no wonder that so many of us crave moments of peace and quiet, a chance to escape the cacophony and immerse ourselves in our own auditory world. This is where noise-canceling technology comes in, and the Cleer Ally Plus True Wireless Earbuds are a prime example of how far this technology has come.
A Brief History of the Hush
The quest for quiet is nothing new. For centuries, people have sought ways to block out unwanted noise. Early attempts were simple, like plugging your ears with your fingers or using earmuffs. But the development of active noise cancellation (ANC) in the 20th century marked a major breakthrough. The first ANC systems were bulky and expensive, primarily used in aviation. Over time, however, the technology has become smaller, more affordable, and more effective, making its way into consumer headphones and earbuds like the Cleer Ally Plus.
Active Noise Cancellation: Fighting Fire with Fire (or Sound with Sound)
Active Noise Cancellation might seem like magic, but it’s actually based on a fundamental principle of physics: wave interference. To understand how it works, we need to understand a little bit about sound itself.
Sound travels in waves, much like ripples spreading across a pond. These waves have peaks and troughs. The frequency of a wave determines its pitch – high-frequency waves sound high-pitched, and low-frequency waves sound low-pitched. The amplitude of a wave determines its loudness – larger amplitude means louder sound.
Now, imagine two sets of ripples on a pond. If the peaks of one set of ripples meet the peaks of another set, they combine to create even larger ripples. This is called constructive interference. But if the peaks of one set of ripples meet the troughs of another set, they cancel each other out. This is called destructive interference.
ANC works by using destructive interference to cancel out unwanted noise. Here’s how:
-
Microphones Listen to the Noise: Tiny microphones on the earbuds “listen” to the ambient noise around you. There are two main types of microphones used in ANC systems:
- Feedforward microphones: These are located on the outside of the earbud and listen to the noise before it reaches your ear.
- Feedback microphones: These are located on the inside of the earbud, near the speaker, and listen to the sound that does reach your ear.
-
Digital Signal Processing (DSP): The signals from the microphones are sent to a Digital Signal Processor (DSP) chip. This chip is the “brain” of the ANC system. It analyzes the incoming noise and creates an “anti-noise” wave that is exactly the opposite of the noise wave – its peaks align with the noise wave’s troughs, and its troughs align with the noise wave’s peaks.
-
Anti-Noise is Played Back: The anti-noise wave is then played back through the earbud’s speakers, along with your music (if you’re listening to any).
-
Cancellation Occurs: When the original noise wave and the anti-noise wave meet inside your ear canal, they cancel each other out, resulting in silence (or at least a significant reduction in noise).
Hybrid ANC: The Best of Both Worlds
The Cleer Ally Plus uses hybrid ANC, which means it combines both feedforward and feedback microphones. This provides more comprehensive noise cancellation, as it can address both the noise that’s approaching your ear and the noise that manages to get past the earbud’s seal.
Sound Quality: More Than Just Silence
While noise cancellation is a crucial feature, it’s not the only thing that matters when it comes to a great listening experience. Sound quality is equally important. And this is where the drivers inside the earbuds come into play.
Headphone drivers are essentially tiny loudspeakers. They convert electrical signals into sound waves. The most common type of driver is the dynamic driver, which uses a diaphragm attached to a voice coil. When an electrical current passes through the voice coil, it creates a magnetic field that interacts with a permanent magnet, causing the diaphragm to vibrate and produce sound.
The Cleer Ally Plus uses 10mm dynamic drivers with neodymium magnets. Neodymium is a rare-earth element that creates a very strong magnetic field for its size. This allows for more powerful and precise movement of the diaphragm, resulting in:
- Stronger Bass: Neodymium magnets can generate a stronger magnetic field, that enables powerful bass.
- Clearer Highs: The precise movement of the diaphragm also allows for accurate reproduction of high frequencies.
- Lower Distortion: A stronger magnetic field means the driver can move more efficiently, reducing distortion.
Frequency response refers to the range of frequencies (from low bass to high treble) that a headphone can reproduce. A wider frequency response generally means a more accurate and detailed sound.
Introducing the Cleer Ally Plus: Science in Action
The Cleer Ally Plus True Wireless Earbuds are a showcase for all these principles. They combine sophisticated hybrid ANC technology with high-quality drivers to deliver a listening experience that’s both immersive and enjoyable.
Deep Dive: Hybrid ANC in the Ally Plus
The Ally Plus’s hybrid ANC system uses both external (feedforward) and internal (feedback) microphones to capture a wider range of noise frequencies. The DSP chip then processes these signals, creating an anti-noise wave that’s tailored to the specific noise environment. This results in effective noise reduction across a broad spectrum of sounds, from the low rumble of a bus engine to the higher-pitched chatter of a busy café.
Deep Dive: The Sound Signature of the Ally Plus
The Ally Plus is known for its powerful and well-defined bass response, thanks to those 10mm neodymium drivers. But it’s not just about the bass. The earbuds also deliver clear and detailed mids and highs, resulting in a balanced and engaging sound signature that’s suitable for a wide range of musical genres.
The Seal of Approval: The Importance of Ear Tips
Even the best ANC technology can be compromised if the earbuds don’t fit properly. A good seal between the ear tip and your ear canal is crucial for two reasons:
- Passive Noise Isolation: A tight seal physically blocks out external noise, preventing it from reaching your ear. This is known as passive noise isolation.
- ANC Effectiveness: A good seal ensures that the anti-noise wave generated by the ANC system can effectively cancel out the incoming noise. If there’s a leak, the noise can “sneak in,” reducing the effectiveness of the ANC.
The Cleer Ally Plus comes with multiple sizes of ear tips to help you find the perfect fit.
Powering Your Peace: Battery Life
The Cleer Ally Plus earbuds offer up to 10 hours of playback on a single charge, with the charging case providing an additional 20 hours, for a total of 30 hours. This is thanks to the efficient lithium-polymer battery and the power-saving features of Bluetooth 5.0. And if you’re in a hurry, a quick 5-minute charge can give you an hour of playback.
Seamless Connection: The Magic of Bluetooth
The Ally Plus uses Bluetooth wireless technology to connect to your smartphone, tablet, or other devices. Bluetooth transmits audio signals digitally, and different codecs are used to encode and decode the audio. Common codecs include SBC and AAC. AAC, generally offers better audio quality than SBC, especially on Apple devices. The use of modern Bluetooth technology also contributes to a stable and reliable connection, minimizing dropouts and interruptions.
The inclusion of Google Fast Pair 2.0 provides near-instantaneous pairing with compatible Android devices, streamlining the setup process.
Designed for Life: Comfort, Durability, and Control
The Ally Plus earbuds are designed for comfort and durability. Their ergonomic shape and multiple ear tip sizes ensure a secure and comfortable fit, even during extended use. The IPX4 water-resistance rating means they can withstand sweat and light rain, making them suitable for workouts and outdoor activities. The touch controls on the earbuds allow you to easily play/pause music, answer calls, adjust the volume, and activate your voice assistant.
ANC Myths: Busted!
- Myth: ANC blocks out all sound.
- Reality: ANC is most effective at reducing low-frequency, constant sounds, like the drone of an airplane engine or the hum of an air conditioner. It’s less effective at blocking out high-frequency, sudden sounds, like a baby crying or someone talking directly to you.
- Myth: ANC is harmful to your hearing.
- Reality: ANC itself is not harmful. In fact, by reducing the overall noise level, it can actually protect your hearing from damage.
- Myth: ANC completely isolates you from your surroundings.
- Reality: While ANC can significantly reduce noise, it typically doesn’t eliminate it entirely. Most ANC headphones also offer an “ambient mode” that allows you to hear your surroundings when needed.
