I like these
by Jonny GM on 24/11/2017
It’s a return to Soundmagic after forays into other products. I was disappointed , if I’m honest... not with the ST30s or Hifi Headphones, but the lower quality rubbish I’ve been putting up with in between.

The ST30s take a little setting up to adjust them to your lugholes - which size/type of tips to use, whether to use the over-ear supports (or the glasses alternative) or not.

When I find the right set-up, they’re pretty reasonable. If it’s not quite right, the sound will be empty and tinny; a good fit gives a happy all-round sound.

Audiophiles will tell you that Boss will do a lot better... you’d be upset if they didn’t at 6x the £££!!

For me, listening to podcasts and background music on my commute, and blocking out the train tannoy telling me how to dismantle a suspect package, these are great for a reasonable price.

And look what comes in the box.

And what a nice box it is, too.

I can’t say how long-lasting they are - I’ve only just got them and they haven’t broken yet. The battery gives me most of the day listening on and off. Happy days.

Quick delivery from the team, too.

4/5 because nobody gets 5 without giving me a free Tesla!
