Picture this: you’re lying in bed, trying to tune out the world, and you’ve got these little earbuds that barely weigh anything nestled in your ears. That’s the vibe with the 1MORE ComfoBuds Z. They’re built for low-key nighttime use, but they’re not just a one-trick pony, they handle music and podcasts too. So, what’s under the hood of these pint-sized gadgets? Let’s break it down, piece by piece!

What Makes the ComfoBuds Z Tick?

The 1MORE ComfoBuds Z aren’t your typical earbuds. They’re small, light, and designed to stay out of the way, especially when your head’s on a pillow. But there’s more to them than just size. Here’s a look at what they’re all about, from how they’re built to how they connect.

Design and Build: Small but Mighty

These earbuds are tiny, seriously tiny. Each one measures 24 x 9.2 x 14.2 mm, which means they sit flush in your ear without sticking out like some bulkier models. Think of them as the earbud version of a minimalist’s dream. They weigh just 2.7 grams apiece, so light you might forget they’re there. The charging case isn’t much bigger, clocking in at 60 x 30 x 38.5 mm and tipping the scales at 34 grams on its own, or 39.4 grams with the buds inside.

The earbuds come with four sizes of silicone tips - extra small, small, medium, and large, so you can swap them out to fit your ears just right. The tips are soft and flexible, designed to sit snugly without feeling like they’re digging in. The case, meanwhile, has a simple, egg-shaped design with a matte finish and a single LED on the front to show battery status: green for full, orange for medium, red for low. It’s all pretty no-frills, but it gets the job done.

Battery Life: How Long They Last

Battery life is a big deal with wireless earbuds, and the ComfoBuds Z keep things practical. Each earbud has a 30 mAh battery, while the charging case packs a 410 mAh one. Here’s how that shakes out in real use:

1. Bluetooth Mode: You get about 2.5 hours of playtime on a full charge if you’re streaming music or podcasts the usual way.

2. BLE Mode: Switch to Bluetooth Low Energy (BLE), and that bumps up to 3.5 hours.

3. With the Case: The case can recharge the buds multiple times, giving you up to 10 hours total in Bluetooth mode or 14 hours in BLE mode before you need to plug it in.

Charging’s straightforward too. The earbuds take 75 minutes to fill up in the case, and the case itself needs 65 minutes via its USB-C port. No wireless charging here, but the USB-C cable comes in the box, so you’re set from the start.

Sound Setup: What You Hear

The ComfoBuds Z use a full-range balanced armature driver to handle audio. That’s a fancy way of saying they’ve got a single component per earbud that’s tuned to deliver sound across the spectrum. The speaker impedance is 22 ohms, which is on the higher side for earbuds but works fine with their low-power design. Frequency range? It’s listed as 2.400 GHz to 2.4835 GHz, though that’s more about the Bluetooth connection than the audio itself, expect a typical range for human hearing, roughly 20 Hz to 20 kHz.

They don’t have active noise cancellation, but the in-ear fit blocks out up to 24 dB of outside noise passively. That’s enough to muffle background sounds like a fan or distant traffic. You can switch between two listening modes via the 1MORE MUSIC app: “Music” for streaming and “Soothing” for built-in sounds like rain or wind. More on that later.

Connectivity: Staying Linked Up

Wireless earbuds live or die by their connection, and the ComfoBuds Z keep it simple with Bluetooth 5.0. Here’s how it all comes together.

Bluetooth Basics

• Version: Bluetooth 5.0, which means decent range and stability compared to older versions.

• Profiles: Supports A2DP (for audio streaming), AVRCP (for remote control), and BLE (for lower power use). No fancy HD codecs like aptX here, just the standard SBC and AAC.

• Range: Up to 10 meters in open space, though walls or interference might cut that down a bit.

Pairing’s easy. Take the buds out of the case, and they power on and pair with each other automatically. A flashing white LED on each bud shows they’re ready to connect to your phone. After the first pairing, they’ll link back up with your device whenever you pull them out, unless you reset them by holding the case’s pairing button for 3 seconds.

No Frills, No Fuss

There’s no touch controls, microphones, or sensors here. Want to pause your music or skip a track? You’ll need to grab your phone. It’s a trade-off for keeping the buds small and light, and it means they’re focused on the basics: playing sound without extra bells and whistles.

In the Box: What You Get

When you crack open the ComfoBuds Z package, here’s what’s inside:

1. The earbuds themselves (left and right).

2. A charging case.

3. Four pairs of silicone ear tips (XS, S, M, L).

4. A USB-C charging cable.

5. A user guide and warranty info.

6. A cloth pouch for carrying everything.

It’s a lean setup, no extra adapters or fancy add-ons, just the essentials to get you going.

Using the ComfoBuds Z: The Tech Details

Let’s get into how these earbuds actually work day-to-day, from fitting them in your ears to tweaking settings in the app.

Fit and Comfort

The ComfoBuds Z are built to sit flush in your ears, which makes them handy for folks who rest on their side or don’t like bulky buds sticking out. The silicone tips come in four sizes, so you can try a few to find what feels right. They’re light enough that you might not notice them after a while, and the in-ear design helps block out some noise without any fancy tech.

Powering Up and Pairing

• Power On: Pull the buds out of a charged case, and they switch on automatically.

• Power Off: Pop them back in the case, and they turn off and start charging.

• Pairing Mode: If they don’t pair right away, press the case’s pairing button for 3 seconds until the LEDs flash white. For single-ear use, double-click the button to set them up separately.

If they won’t connect to your phone, make sure they’ve got some juice, charge them for at least 30 minutes if they’re dead. After pairing once, they’ll reconnect automatically unless you’re too far out of range (over 10 meters). To reconnect, just tap their name in your Bluetooth settings.

Charging Breakdown

• Earbuds: Fully charge in 75 minutes inside the case. A glowing white LED on each bud means they’re topped off.

• Case: Takes 65 minutes with a USB-C cable (5V 1A input). The front LED shows the case’s status while charging.

If you haven’t used them in a while, like over three months, it’s a good idea to charge them fully to keep the battery in shape. Stick to standard USB-C cables and adapters to avoid any hiccups.

Audio Modes and the App

The 1MORE MUSIC app (available for iOS and Android) is where you control what these buds do. It’s pretty basic but covers the essentials:

• Music Mode: Streams whatever’s on your phone - music, podcasts, you name it.

• Soothing Mode: Plays one of 30 built-in sounds stored on the buds themselves, like breeze or drizzle. You can download your picks from the app’s playlist and set a timer (30, 60, 90, 120, or 150 minutes) to shut them off automatically.

Volume for soothing sounds adjusts in the app, not your phone’s buttons, since they run off the buds’ internal memory. No custom timers here, just those five preset options.

What’s Missing?

The ComfoBuds Z strip things down to keep them small and focused. Here’s what you won’t find:

1. Microphones: No calls or voice commands.

2. Touch Controls: Use your phone for play, pause, or volume.

3. Active Noise Cancellation: Just passive blocking from the fit.

It’s a trade-off for their size and simplicity, less tech, but less bulk too.
