Every producer hits that wall — the beat sounds great in your headphones, then falls apart on a phone speaker, a car system, or a professional studio monitor. More often than not, it's not the arrangement that's the problem. It's the mix.
After years of producing and working with artists across the UK and beyond, the same issues keep coming up. Here are the five mistakes I see most often — and exactly how to approach fixing them.
1. Too much low-end from too many sources
Bass is the most common culprit behind muddy, unprofessional-sounding beats. The problem usually isn't that there's too much bass — it's that too many elements are competing in the same frequency range. Kick, bass, 808, sub-layer on a synth — they can all pile up below 200Hz without you realising it.
The fix is high-pass filtering. Every element that isn't supposed to carry bass weight should have a high-pass filter applied, typically somewhere between 80Hz and 200Hz depending on the instrument. Roll off the bottom end of your hi-hats, your mid-range synths, your pads — anything that doesn't need to live in the sub. You'll be surprised how much space opens up.
2. Drums that don't cut through on small speakers
Producers often mix drums on full-range monitors and wonder why the kick disappears on a phone. The issue is that the perceived power of a drum hit comes from transient attack — the sharp, fast initial pop — not just the low-end body.
Focus on the 60–100Hz range for the fundamental of your kick, but pay equal attention to the 2–5kHz range where the click and attack live. If those frequencies are present and balanced, the kick will translate on every system. Use a transient shaper if you need more punch without adding boom.
3. Reverb that blurs everything together
Reverb is one of the most useful tools in music production — and one of the easiest to misuse. Long reverb tails on lead elements, particularly snares and vocals, can make a mix feel cloudy and indistinct. Everything starts to blur into everything else.
Two things help here. First, use pre-delay on your reverb. Even 20–40ms of pre-delay creates a separation between the dry signal and the reverb tail, keeping the transient sharp before the space opens up. Second, high-pass your reverb return — remove the low-end rumble from your wet signal so it's not adding mud to the mix.
4. Over-compression that kills the dynamics
Compression is a tool for controlling dynamics, not eliminating them. When everything in a mix is compressed into a flat, even level, the result is fatiguing to listen to and lacks energy. The kick and snare stop feeling like events. Everything sounds the same volume all the time.
Use compression to glue and control, not to squash. Aim for gain reduction of 3–6dB on most elements, with a fast attack and medium release to preserve the transient. Leave headroom in your mix — aim for peaks around -6dBFS rather than pushing everything to zero. Your mastering stage will thank you, and the mix will breathe.
5. Mixing in solo too much
This one's counterintuitive, but soloing individual tracks to mix them is one of the most common mistakes producers make. Elements that sound perfect in solo often don't sit right in context — and elements that sound slightly wrong in solo can work perfectly in the full mix.
Mix in context as much as possible. Reference your mix on different systems — laptop speakers, earbuds, your car — every 20–30 minutes. These translation checks will tell you more about what your mix needs than any amount of solo work on a single element.
These aren't complicated fixes. Most of them take minutes to apply. But getting them right consistently is what separates beats that sound like they were mixed in a bedroom from tracks that hold up in a professional setting.
