“Heil Pro 7 vs Sennheiser HMD 300 Pro. This is pretty in-depth – you may need a coffee and a sit down to watch! This was heavier than I expected. Took the best part of Saturday to complete the audio and visual components. I’ve tried to be as fair as I can. My personal conclusion is that if you only want one headset – and only for Ham Radio, maybe the Pro 7 might be the best bet. If you want full range, perhaps recording and listening to full range audio too, maybe the HMD 300 Pros might be best. I have more tests to do including taking these to Isle of Mull for the DXpedition – so watch this space and I’ll see how I get on. Callum. M0MCX.
