Choosing DJ equipment can come down to a basic split: do you need a new mixer for multi-source mixing now, or are you specifically after a CD/MP3-oriented unit with effects and are prepared for a parts-condition project? The Doslnlya XR-4 and Edison Scratch 2500 take distinctly different routes, even though both are black DJ audio mixers.
Quick verdict
Pick the Doslnlya XR-4 Black 4 Channel Professional Bluetooth 5.0 DJ Audio Mixer when four-channel mixing, Bluetooth 5.0, and New condition are the priorities. Its listed price is USD 70.05, which is USD 28.95 lower than the Edison.
The Edison Scratch 2500 Professional Dual CD USB MP3 DJ Audio Mixer is the more specific choice for someone seeking CD/MP3 compatibility, a two-channel digital format, and a broad listed effects set. However, at USD 99.00, it is marked For parts or not working and needs a power cord.

Where each mixer makes more sense
Doslnlya XR-4: four-channel mixing and a new-condition option
The XR-4 has the clearer path for a setup that calls for more than two mixing inputs. Its four-channel designation and Bluetooth 5.0 are the central differentiators, while the compact black design keeps the presentation straightforward. New condition is also a meaningful practical distinction against the Edison's parts designation. Choose it when your decision is led by channel count and Bluetooth capability rather than dedicated CD/MP3 integration.
Edison Scratch 2500: CD/MP3 format and a wider named effects set
The Scratch 2500 is aimed at a different kind of shopper: one drawn to its dual CD USB MP3 identity and listed compatibility with CD and MP3 players. It also names more individual effects, including delay, distortion, dub echo, echo, filter, and flanger, alongside 3-band and 4-band equalizer features. Those format and effect details are compelling only if the unit's parts condition fits the intended use.
Product notes
Edison Scratch 2500 Professional Dual CD USB MP3 DJ Audio Mixer
The reason to choose the Edison Scratch 2500 is its unusually specific format: a digital, two-channel mixer built around dual CD, USB, and MP3 use. Its listed effects collection gives an effects-focused setup several named tools to work with, from echo and filter to flanger and distortion. CD/MP3-player compatibility and the 3.5 mm TRS input/output ports further define its music-playback orientation. The limitation is substantial rather than minor: the mixer is marked For parts or not working, needs a power cord, and has front knobs pushed in; one low-EQ knob is also described as loose. It suits a shopper who wants this particular feature mix and accepts a repair-oriented condition.
Doslnlya XR-4 Black 4 Channel Professional Bluetooth 5.0 DJ Audio Mixer
The Doslnlya XR-4 is the more direct choice for someone who wants a New black mixer with four-channel mixing input and Bluetooth 5.0 in the product name. Its description also emphasizes multi-device connection, reverb and digital effects, loopback sound synthesis, and stereo output, making it oriented toward combining sources rather than centering the setup on CD/MP3 playback. The compact dimensions listed in the description reinforce its small-format approach. Its trade-off is simply a different feature emphasis: the XR-4 does not carry the Edison's dual-CD USB MP3 identity or its long list of individually named effects. Choose it for channel capacity and Bluetooth-led flexibility, not for a dedicated CD-player-style format.
Final choice by use case
For a new four-channel Bluetooth mixer, choose the Doslnlya XR-4. For a CD/MP3-compatible digital mixer with named echo, filter, and flanger effects, the Edison Scratch 2500 is the relevant option-but only where its For parts or not working condition, needed power cord, and knob issues fit the plan.
