If you want the most discreet, portable solution for sleeping with active noise cancellation and a compact case, choose Avantree Relay; if you need superior battery life, deep bass, and over-ear comfort for long listening sessions, choose RCA Wave-56.
• Avantree Relay: Delivers hybrid active noise cancellation in an ultra-portable in-ear design with Bluetooth 5.3 aptX support, but sacrifices the extended battery life of larger headphones.
• RCA Wave-56: Offers up to 40 hours of total playtime with Hi-Res audio and plush over-ear cushions, yet lacks active noise cancellation and is too bulky for side-sleeping.
• The Verdict: Pick Avantree Relay if you prioritize blocking out snoring or travel noise while lying down; pick RCA Wave-56 if you want all-day listening from a couch or bed without worrying about charging.
The Avantree Relay is engineered for the listener who needs to disconnect from the world without disconnecting from their device. As an in-ear system featuring Hybrid Active Noise Cancellation, it actively blocks out up to 24dB of environmental noise. This specific capability makes it a standout choice for those looking for earbuds for sleeping, as the physical seal combined with electronic cancellation creates a quiet zone around your ears. The rounded tips are designed to sit flush within the ear canal, minimizing pressure points that often occur with bulkier hardware when lying on your side.
For commuters or travelers, the versatility of the Relay is its strongest asset. It functions not just as earbuds but as a premium airplane Bluetooth adapter compatible with any AUX output, including older inflight entertainment systems. With Bluetooth 5.3 and aptX-Adaptive support, it ensures low latency and high-quality transmission even when connecting to older devices via the included dual 3.5mm adapters. If you frequently fly or watch TV in noisy environments, this two-in-one functionality removes the need to carry multiple dongles or adapters.

However, this form factor comes with trade-offs. Because the unit relies on small internal batteries to power the drivers and ANC chip, the battery life will naturally be shorter than that of full-size over-ear headphones. It also lacks the "over-ear" cushioning found in larger models, which means some users might find them less comfortable for marathon listening sessions compared to softer, padded alternatives. But for anyone whose primary goal is to block out the world while sleeping or commuting in tight spaces, the compact, noise-canceling design is unmatched.
The RCA Wave-56 is built for the user who values endurance and immersive sound quality above portability. These are over-ear headphones featuring plush ear cups made of plastic with fabric and memory foam, designed specifically for extended wear without strain. The adjustable headband and lightweight frame allow you to wear them for hours, making them ideal for work sessions, long flights, or relaxing at home where you don't have to worry about pressing against a pillow. If you are searching for the best wireless earbuds for sleeping but prefer the security of a headband that won't fall out, these provide a stable fit that stays put during movement.
Sound enthusiasts will appreciate the Hi-Res Audio certification and the enhanced bass performance. The dynamic drivers cover a frequency range from 20 Hz to 40 kHz, delivering crystal-clear highs and deep, resonant lows that smaller in-ear units often struggle to reproduce. The transparency mode is also a practical feature here, blending ambient sounds into your audio so you can stay aware of traffic or conversations without removing the headphones. This balance between isolation and awareness makes them excellent for outdoor activities or busy commutes where safety is a concern.
The defining advantage of the Wave-56 is its battery longevity. With an average battery life of 40 hours, you can go days without plugging them in, which is significantly more than what most true wireless earbuds offer. This makes them perfect for the "set it and forget it" user who wants reliable playback for a week-long trip or a month of daily commutes. However, the lack of active noise cancellation means they rely solely on passive sound isolation from the ear cups, and the over-ear design simply cannot fit comfortably under a pillow like in-ear buds can.
• Best for sleeping on your side → Avantree Relay, due to its low-profile in-ear shape that doesn't protrude from the ear.
• Best for long battery life → RCA Wave-56, offering 40 hours of continuous playtime versus the limited capacity of small earbuds.
• Best for noise blocking → Avantree Relay, because it features Hybrid Active Noise Cancellation that cuts out up to 24dB of noise.
• Best for sound depth and bass → RCA Wave-56, with Hi-Res Audio and enhanced bass technology that over-ear drivers handle better.
• Best for travel adaptability → Avantree Relay, as it doubles as a Bluetooth transmitter for airplane AUX ports and gym equipment.
• Best for comfort during long sessions → RCA Wave-56, thanks to plush memory foam ear cups and an adjustable headband.
• Best for staying aware of surroundings → Both offer transparency modes, but the Wave-56 does so while maintaining open-back style airflow.
• Best value for audiophiles → RCA Wave-56, providing studio-quality audio fidelity that exceeds the frequency response of standard earbuds.
After weighing the specifications and real-world use cases, I would choose the Avantree Relay if my primary goal was finding earbuds for sleeping. The combination of active noise cancellation and the ability to lie flat on your side without discomfort is a game-changer for rest. While the RCA Wave-56 offers incredible battery life and rich sound, its over-ear design simply prevents it from being a viable option for nighttime use. In my opinion, the Avantree Relay is the superior choice for anyone prioritizing sleep quality and portability, whereas the RCA Wave-56 remains the champion for daytime listening and long-duration audio consumption.
The Avantree Relay is the clear winner here because it features Hybrid Active Noise Cancellation that blocks up to 24dB of environmental noise, unlike the RCA Wave-56 which only offers passive sound isolation.
The RCA Wave-56 lasts significantly longer with an average battery life of 40 hours, making it better for long trips, while the Avantree Relay requires more frequent charging due to its smaller in-ear form factor.
The Avantree Relay includes a compact case and acts as a Bluetooth adapter for planes, making it highly portable, whereas the RCA Wave-56 is larger and includes a protective case but takes up more space in a bag.
The RCA Wave-56 wins on raw audio fidelity with Hi-Res Audio certification and a frequency range up to 40 kHz, offering deeper bass and clearer highs than the standard range of the Avantree Relay.
