How to Use Memorex Wireless Headphones (Without Frustration): A 7-Step Setup Guide That Fixes Bluetooth Pairing Failures, Battery Confusion, and Sound Dropouts in Under 5 Minutes

By James Hartley · December 20, 2023

Why Getting Your Memorex Wireless Headphones Right Matters More Than You Think

If you've ever asked how to use Memorex wireless headphones, you're not alone—and you're probably already experiencing one of three silent frustrations: the headphones won’t pair after the first charge, the left earbud cuts out during calls, or the battery dies after just 45 minutes despite the box claiming '20 hours.' These aren’t quirks—they’re symptoms of misconfigured Bluetooth profiles, undercharged lithium-ion cells, or overlooked firmware behavior. In 2024, over 63% of wireless headphone returns stem from setup confusion—not hardware defects (Consumer Technology Association, 2023). That means your headphones likely work perfectly—if you know how to speak their language.

Step 1: Power Up & Charge Correctly (The #1 Mistake)

Before touching any button, plug in your Memorex wireless headphones using the included micro-USB or USB-C cable (check model: MX-BT500 uses micro-USB; MX-BT700 uses USB-C). Here’s what most users miss: Memorex units ship with ~30–40% charge—not zero, but *not enough* for stable Bluetooth negotiation. Charging for just 15 minutes unlocks full pairing mode; skipping this causes erratic LED behavior and failed connections.

Use only a 5V/1A wall adapter (not a fast-charging phone brick). Why? Memorex charging circuits lack voltage regulation for >5V inputs—overvoltage stresses the 3.7V Li-ion cell and degrades cycle life by up to 40% over 12 months (per IEEE Std. 1624-2022 battery safety guidelines). A red LED pulsing slowly = charging; solid red = fully charged (typically 2.5 hours). Never leave them plugged in overnight—the built-in cutoff is reliable, but thermal stress accumulates.

Pro tip: After first charge, do a full discharge-recharge cycle once every 90 days. This recalibrates the fuel gauge IC so the battery indicator matches actual runtime—not estimated.

Step 2: Pairing Done Right—Not Just 'Turn On & Hope'

Memorex headphones use Bluetooth 5.0 (MX-BT500) or 5.2 (MX-BT700), supporting SBC and AAC codecs—but not LDAC or aptX. That matters: AAC delivers richer mids on iOS, while SBC dominates Android. To pair:

Power on headphones by holding the center button for 5 seconds until blue/red LED alternates rapidly (this is pairing mode, not power-on).
On your device, go to Bluetooth settings → 'Add Device' (not 'Connect').
Select 'Memorex MX-BTxxx'—not 'MEMOREX' or 'BT-Headset', which are legacy aliases that cause profile mismatches.
When prompted, tap 'Pair'—do not enter PINs. Memorex uses Secure Simple Pairing (SSP); entering '0000' or '1234' forces legacy mode and breaks call audio routing.

Once paired, the LED turns solid blue. If it blinks blue/white, you’re in multipoint mode (MX-BT700 only)—a feature many don’t realize requires manual toggling via triple-press, not automatic switching.

Case study: Sarah K., remote educator, spent 3 days troubleshooting echo on Zoom calls. Her MX-BT500 was paired to her laptop *and* phone simultaneously—causing A2DP (music) and HSP/HFP (call) profiles to conflict. Solution: Unpair from one device, then re-pair with HFP priority enabled in laptop Bluetooth settings. Call clarity improved instantly.

Step 3: Mastering Controls & Audio Profiles

Memorex wireless headphones use tactile, not touch-sensitive, controls—a deliberate choice for reliability. But button mapping varies by model:

Single press (center button): Play/pause (music) OR answer/end call.
Double press: Skip forward (music) OR reject incoming call.
Triple press: Activate voice assistant (Siri/Google) OR toggle multipoint (MX-BT700 only).
Press-and-hold (2 sec): Volume up/down—not swipe.

Crucially: The 'volume' command only works when audio is playing. If you adjust volume while paused, the setting resets at next play. This isn’t a bug—it’s Bluetooth AVRCP 1.6 compliance, ensuring consistent behavior across devices (confirmed by Memorex firmware v2.11 changelog).

For audiophiles: Memorex doesn’t offer EQ presets, but you *can* shape sound via your source. On Android, enable 'Bluetooth Audio Codec' in Developer Options and select AAC for wider stereo imaging. On iOS, AAC is auto-selected—but disable 'Low Latency Mode' in Settings > Accessibility > Audio/Visual to prevent compression artifacts during podcasts.

Step 4: Troubleshooting Real Problems (Not 'Restart Bluetooth')

Most online guides say 'forget device and restart'—but that ignores root causes. Here’s what actually works:

Sound drops out intermittently?

This is almost always RF interference—not weak batteries. Memorex BT500 operates at 2.4GHz, sharing bandwidth with Wi-Fi routers, microwaves, and baby monitors. Test: Move 10 feet away from your router. If dropout stops, relocate your router’s 2.4GHz band to Channel 1 or 11 (least congested per Wi-Fi Alliance spectrum maps). Also, avoid wearing Bluetooth headsets under metal-framed glasses—the frame acts as a Faraday cage, attenuating signal by 12–18dB (measured in anechoic chamber test, AES Convention Paper 104-000123).

Left earbud silent?

Unlike true wireless earbuds, Memorex over-ear models have a physical L/R channel link. Check the hinge joint near the left ear cup: debris (lint, hair) can break the gold-plated contact pin. Use a dry, soft-bristled brush—not compressed air—to clean. If still silent, perform a hard reset: hold power + volume down for 10 seconds until LEDs flash red/blue 3x. This clears the Bluetooth address cache without erasing firmware.

Battery drains in 2 hours?

Check ambient temperature. Lithium-ion cells lose 30% capacity below 10°C (50°F) and degrade 2x faster above 35°C (95°F). Store and charge between 15–25°C. Also verify auto-off: MX-BT700 defaults to 15 min idle timeout; MX-BT500 uses 5 min. Extend via firmware update (see 'Support' tab on memorex.com/support/bt700).

Frequently Asked Questions

Do Memorex wireless headphones work with PlayStation or Xbox?

Officially, no—neither console supports standard Bluetooth audio input for headphones (PS5 requires USB dongle; Xbox requires Xbox Wireless protocol). However, you *can* use them with a third-party Bluetooth transmitter like the Avantree DG60 (tested with MX-BT700), which plugs into the controller’s 3.5mm jack. Latency is ~120ms—acceptable for movies, not competitive gaming. For zero-latency, use wired connection via the included 3.5mm aux cable.

Can I replace the ear cushions myself?

Yes—and you should every 18–24 months. Memorex sells OEM replacements (part #MC-MX700-EAR for MX-BT700; MC-MX500-EAR for MX-BT500) for $12.99. DIY replacement takes <2 minutes: peel off old cushion, align new cushion’s inner ridge with the plastic groove, and press firmly clockwise until seated. Avoid generic cushions—they often lack the 15mm memory foam density needed for proper acoustic seal and passive noise isolation (verified by independent lab test, Audio Precision APx555).

Is there a way to update firmware?

Only via Memorex’s desktop app (Windows/macOS), not mobile. Download 'Memorex Audio Suite' from memorex.com/support. Firmware updates fix known issues like iOS 17.4 call routing bugs and improve multipoint stability. As of April 2024, latest versions are v2.11 (MX-BT500) and v3.04 (MX-BT700). Updates take 90 seconds—do not disconnect during transfer.

Why does my voice sound muffled on calls?

The MX-BT500 uses a single beamforming mic; MX-BT700 uses dual mics with AI noise suppression. Muffled voice usually means the mic port (small hole near hinge) is blocked by fabric or pocket lint. Clean with a toothpick wrapped in microfiber cloth—never use liquids. Also, ensure 'Voice Isolation' is enabled in your phone’s Accessibility settings (iOS) or 'Noise Suppression' in Android Sound Settings.

Are these waterproof?

No IP rating—Memorex wireless headphones are not water-resistant. Sweat exposure degrades the earpad foam and corrodes internal contacts over time. If you exercise with them, wipe daily with a dry cloth and store in the ventilated case. For gym use, consider the Memorex Sport Series (IPX4 rated) instead.

Common Myths

Myth 1: “Leaving them on charge overnight ruins the battery.”
False. All current Memorex models include CE-certified overcharge protection. The real risk is heat buildup from poor ventilation—so never charge inside a closed drawer or under a pillow. Ambient temps above 30°C accelerate degradation more than extended charging.

Myth 2: “Higher Bluetooth version = better sound quality.”
Misleading. Bluetooth 5.2 improves range and stability—not codec support. Since Memorex only supports SBC/AAC (same as BT 4.2), upgrading from BT 5.0 to 5.2 yields no audible difference in fidelity. It *does* reduce dropouts in crowded RF environments, though.
