Which Sennheiser microphone should I buy for live vocals?

For a wired vocal setup, start by comparing the e945 (£167) and e935 (£169). Those are the supplied best new prices, so there’s little between them on cost. Try both through a similar PA if possible: how each suits your voice matters more than that small saving.

The XSW 2-865 wireless handheld system (£418) is the option to consider if stage movement is a priority. This listing is the E Band version; confirm that its frequencies are suitable and permitted where you’ll use it, including any licensing requirements.

Don’t assume spending more automatically gets you the better vocal match. The MD 441-U (£1,080) is a supercardioid dynamic microphone, but its higher price alone isn’t a reason to choose it over a dedicated vocal option. Buy for the job, and leave room in the budget for the rest of your setup.
