I picked up these SoundPEATS headphones for £26 from Amazon and they are far, far better than they have any right to be for that price:
I already have a pair of KZ6 in-ear monitors, which in their wired configuration are probably the best in-ear headphones I've ever owned. They come wired as standard, but you can swap out the wires for a bluetooth module if you don't mind sacrificing convenience for sound quality (which I don't). Alas, while sounding great, they suffer from the same problem as most other bluetooth earbuds: the battery module. This usually sits a little way down from one of the earbuds and makes them slightly heavier on one side and swings as you walk. It's a minor design issue - but I want to be able to forget that I have the earbuds in.
Truly wireless earbuds seemed to be what I was looking for. I did some research on what was available and found some that sounded good on paper, but almost all came at considerable outlay. Apple's AirPods would be the obvious choice but they're really expensive and look a little odd. These SoundPEATS headphones are listed at £32 on Amazon, with over two hundred reviews and a four and a half star rating (plus a 20% discount when I ordered). I'm normally suspicious of unknown brands with loads of good ratings but at this price they seemed worth a punt.
There isn't much in the box - just the headphones, the charging box, a tiny USB cable, some different sized tips and a small manual. I had a little trouble getting the earbuds to connect to each other at first but since I figured it out now they connect automatically (you have to take the right one out of the charger first). The sound quality won't blow you away but it's far from awful - and these are over a hundred quid cheaper than AirPods. They are advertised as sweat and splash proof, but not waterproof. Battery life is supposed to be around 3 hours and the case will charge them three to four times before it needs charging. I can't exaggerate how handy it is to be able to charge your headphones while they are in your pocket and have them fully charged when you need them. The connectivity is excellent too. I haven't had any stuttering with my phone in my bag or my back pocket. They even work well with the Apple Watch.
Based on what I've seen so far, I'd highly recommend these if you want to see if truly wireless earbuds are for you.
