If you want a dedicated replacement cable for older JBL portable speakers like the Charge 3 or Flip 4, choose SCOVEE Charger Cord; if you need a modern 2-in-1 adapter to listen on wired headphones while fast charging your latest smartphone or laptop, choose Mxcudu USB C. These two products solve completely different problems in the audio ecosystem, and picking the wrong one leaves you with a dead device or a speaker that won't turn on.
• SCOVEE Charger Cord: Its strength is being a specialized, durable flat Micro-USB cable designed specifically for legacy JBL speakers (Charge 2 through Charge 3) and Logitech UE Boom units; its trade-off is zero compatibility with any modern Type-C devices or new phones.
• Mxcudu USB C: Its strength is combining Hi-Res audio output via a 3.5mm jack with 60W Power Delivery charging in a single compact dongle for newer smartphones and laptops; its trade-off is that it cannot transfer data and is useless for older speakers with Micro-USB ports.
• Who is this for?: The SCOVEE pick is for teachers still relying on older classroom speakers or students with vintage gear, while the Mxcudu pick is for anyone using iPhone 16/15 series or Samsung Galaxy S24/S23 devices who needs to multitask audio and power.
This product exists for a very specific niche of users who own older generations of portable Bluetooth speakers. If you are a teacher who has been using the same JBL Charge 3, Flip 4, or Clip 2 in your classroom for years, you know the frustration of losing the original charger. This cord is built to fill that exact gap. It features a flat design which is a practical choice for travel, reducing the chance of tangling in a backpack or bag compared to round cables. The bright red color makes it easy to spot among other black cords in a chaotic environment.
The technical specifications highlight its purpose clearly. It supports fast charging up to 2.4A and syncs data at speeds up to 480Mb/s, ensuring your older speaker charges quickly without draining your battery for hours. However, you must be extremely careful about compatibility. It also excludes newer Logitech speakers that have moved to Type-C. If your speaker has a rounded, smaller USB port, this Micro-USB connector will fit perfectly; if it has the oval, reversible port found on modern tech, this cable simply will not plug in.

You should buy this if you have a JBL SOUNDGEAR, GO 2, Pulse 3, Charge 2+, Charge 3 Special Edition, Clip 2, Flip 3, Flip 4, or Micro II speaker. It is also compatible with the Logitech UE Boom. If you are looking for an over ear headphone solution or a bone conduction option, this cable is irrelevant because those devices usually charge via their own proprietary ports or standard Micro-USB inputs that might differ slightly. This is strictly a replacement power supply line. You should skip this entirely if you are trying to charge a modern phone, tablet, or the newest generation of JBL speakers, as the physical connector type is fundamentally different.
This adapter targets the modern user who has embraced the trend of removing the headphone jack from smartphones and tablets. If you are a teacher using an iPhone 16 Pro Max or a Samsung Galaxy S24 Ultra, you likely own wired headphones for better sound quality during quiet study sessions but find yourself needing to charge your device simultaneously. This unit solves that by splitting your single USB-C port into two distinct functions: a 3.5mm audio jack and a USB-C charging port. It allows you to listen to music or take calls while the device receives power, preventing the battery from draining during long lectures or commutes.
The performance capabilities here are robust for a small dongle. It includes a built-in Realtek DAC chip capable of decoding Hi-Res audio up to 32Bit/384Khz, which ensures high fidelity sound without the compression often associated with cheap adapters. It also supports 60W Power Delivery (PD), meaning it can handle fast charging standards like PD, QC, AFC, and PPS. This makes it versatile enough to charge not just phones, but also larger devices like the iPad Pro or MacBook Air. The construction uses nylon braided cable and TPE material, suggesting a focus on durability against daily wear and tear.
However, there are clear limitations you must accept. This device does not support data transfer; it is purely for audio and power. It is also incompatible with Moto and OnePlus phones, so you must check your device model before purchasing. While it works with most major brands including Apple and Samsung, the inline controls may not function correctly with Apple-branded headphones, even though the audio passes through fine. This is the ideal touch control headphone companion for users who want to manage volume and calls directly from their headset while keeping their device powered. If you need to connect a laptop to a car stereo or a classroom PA system via a 3.5mm cable while charging your laptop, this is the tool for the job.
• Best for legacy JBL speakers → SCOVEE Charger Cord (specifically for Charge 2, 3, Flip 2, 3, 4).
• Best for modern smartphones → Mxcudu USB C (iPhone 16/15, Galaxy S24/S23, Pixel 8/7).
• Best for simultaneous charging and listening → Mxcudu USB C (splits port for audio + 60W PD power).
• Best for flat, tangle-free storage → SCOVEE Charger Cord (flat micro-USB design).
• Best for high-fidelity audio decoding → Mxcudu USB C (supports 32Bit/384Khz via Realtek DAC).
• Best for classroom portability → Mxcudu USB C (lightweight 11g design fits easily in pockets).
• Best for older equipment maintenance → SCOVEE Charger Cord (essential replacement for aging hardware).
• Best for laptop connectivity → Mxcudu USB C (works with MacBook Air/Pro and iPad Pro).
As someone who has seen how quickly technology shifts, I recommend the Mxcudu USB C for the vast majority of people today. In my opinion, the ability to combine 60W fast charging with Hi-Res audio output makes it an indispensable accessory for anyone with a modern smartphone or laptop. It addresses the real-world pain point of having a dead battery while trying to use wired headphones.
For teachers specifically, this adapter offers more value than the SCOVEE cable unless they are managing a room full of older, non-upgradable speakers. The Mxcudu unit keeps your device running longer and sounds better, making it a smarter investment for the current year. That said, do not dismiss the SCOVEE Charger Cord if you are stuck with older gear; it is a lifesaver for those specific legacy models, but it serves a dying market. I would buy the Mxcudu for my own daily carry to ensure I never miss a beat during a long day of teaching.
It only works with older models like the Charge 3 and Flip 4.
No, this adapter is designed solely for audio output and charging. The specifications confirm that it does not support data transfer, so you cannot move photos or documents through this dongle.
While it does not actively cancel noise like electronic ANC, the built-in Realtek DAC chip provides superior decoding with powerful noise reduction and higher fidelity sound to minimize static and distortion during playback.
Yes, the compatibility list confirms it works with the entire iPhone 16 series (including Pro, Pro Max, Plus) as well as iPhone 15 and 14 models, allowing for both audio playback and 60W fast charging.
