They sound fantastic, and better than most at 10x the price!
I'm an audiophile. I'm one of those people who get picky about sound. This pair I would buy over and over again. Just take the default ear fittings OFF and go to the biggest one. You can use red color plugs for the right so you never have to guess which is L or R. Sound is great, and you can wear these without fatigue much at all. I've already bought 3 other styles and the brand is where I go. Not Sony, not Samsung or JBL. It's Betron. Seriously, give it a shot.

Simply wired earbuds
These earbuds are just plain wired earbuds, but they are very sturdy, the wire is a nice thick non-tangle wire. They sound great for my purpose. They include a nice little red velvet pouch to protect them and a set of various size buds in red and black. The red buds are difficult to put on so require patience. Otherwise the black buds fit in my ears very well. There is no online volume control but I didn't want one. These wired earbuds will last a very long time. They're a good purchase. I do recommend if you want to make them bluetooth, buy an APEKX bluetooth unit, available on Amazon, that the earbuds can be plugged into to easily use them wirelessly.

Strongly built, but red finish easily chips off.
I bought these because they are no-frills and durable. They have extra thick cords. Sound quality is good. The only problem is the red finish which appears to be a hard, brittle plastic material. It chips easily. I ended up scraping the red off the buds. The underlying material is a hard white plastic.

Quality keeps decreasing
I used to periodically by these earphones, but I've noticed the quality slowly decreasing over the years. They use to have a flat, red ribbon rather than a typical wire but that's changed. The actual earbud shape has also changed. Maybe 1-2 years ago, they changed their labelling of L and R so it's harder to see. The new ones I tried seemed to break sooner. So I'm now trying on new earphones. Unfortunate they didn't simply keep making the version from around 2021. These earbuds are "fine" but just know you're buying a lower-quality product now. I'd much prefer to pay more for the old, better version.

There are scratches on it!
The sound quality is good regarding its price, but when I recieved it, I found many scratches on it! It is the reason that I rate it by two stars!

They still work years later.
I bought these years ago and they still work. Definitely worth the price.

High quality for your money.
I got these to watch movies so as not to disturb my roommate. The sound quality and the Bass really good the construction and material is very nice. I will start looking for more products made in the UK.

Good deal
I like the fact that you don't have to worry about them getting tangled,the sound quality is good. They feel a little bit uncomfortable but I use them everyday and really enjoy your them. I use them with my cellphone and my tablet.I think I will buy another pair so I will keep a pair at home and one that I have with me when I am away from home.

I bought these as other reviewers had recommended them as rugged and I'm a serial headphone breaker
I bought these as other reviewers had recommended them as rugged and I'm a serial headphone breaker, and I was delighted to find that, not only are they indeed rugged, but they are comfortable and have great sound - rather better than the significantly more expensive Sennheiser earbuds I managed to somehow break recently. I also loved the little fabric bag they came with to store them (and which contains the other sizes of bud). The only thing I would change is the vertical 3.5mm connector into an L-shaped one, because those are less prone to getting knocked around, but anyway, great product, great price.

Everything screams, cheap, nasty....but.........
Ok, first things first, I review many headsets from £5 to over £350, so wanted to try these as I was going to go for some reliable Creative E600's. The packaging, was an an actual chore to get into, and I’m still not sure if I did it right, very nicely presented in foam inserts, usual manual, vouchers and the like. So onto the buds, one thing will not escape you, the cable is like no other cable I have ever experienced, and I mean that on the poor side, it reminded me of some Childs toy microphone, with a shiny, plastic feel, that just looks and feels awful. Comes with a drawstring bag, think mine should have been red, but wasn’t, and the usual replacement Small, Med, Lrg, buds, but surprisingly a set of the new style "Memory foam" buds, however, very battered squashed, in the bag. So you maybe asking how has he given 4 stars, I guess your probably guessing why....for all the cheap nasty look and feel...the sound quality these produce is simply outstanding for a sub £10 set of earbuds. So really if your after a throw about set, then look no further, the sound far outways the looks, they probably won’t last 2 minutes, but still great for the price.

the temperature was between -17 C and -25 C and they worked fine. The cable does not seem to knot and ...
As a runner and a big audio book listener I get through a lot of earphones. I am impressed by the Betron RK300 quality. The cable is soft flexible and strong, an advantage when running as it doesn't chafe your skin and on a recent marathon I was in, the temperature was between -17 C and -25 C and they worked fine. The cable does not seem to knot and tangle as much as others I have had. They also do block out background noise so you can still hear your music or audio book at normal sound levels in one case an 4 hour flight on a Russian military jet where they handed out ear plugs because it was so noisy, and they cope well with buses and trains. At a fraction of the cost of other earphones I have had in the past they are exceptional quality and value for money.

Okay, not great
These were bought as a hopefully sturdy replacement for the Betron B550s that I'd previously purchased and had suffered from an amazingly flimsy cable that gave up the ghost after 6 months of daily light use. Pros: -The cable on these is definitely a higher quality and I don't think they'll go the way of their predecessor any time soon. -Sound quality is acceptable for the price, but the B550s were better in this regard. Cons: -The cable whilst sturdy is short, really short. So short in fact that I can't actually keep my player in my pocket whilst the earphones are in my ears, I instead have to clip it somewhere further up my body, and I am by no means tall. -No quite as nice looking as the B550s. Advice to Betron: take the cable from this, make it longer, and then use it on your Betron B550s model. Then sell at a slightly higher price and discontinue the other two products.

FORGET THEM
There was NO depth of tone whatsoever, Bass quality was rubbish. I have given them to my grand daughter as a back up. I went out to Wilkinsons, and got a cheap Sony replacement which is far better. I am a music arranger and was hoping with the description that yours would be good....but no worries ....neither me or my colleabues who tried them will make the mistake again. They look nice, but thats all . . Sorry, no malice or animosity on my part , but in our opinion .....very, very . very poor indeed.
