RevoNext QT2 Triple Driver In-ear Earphone, Detachable Wired Headphone Earbuds Hifi Stereo Headset with Dynamic Driver and Balanced Armature Hybrid

The first thing I did was change the standard earbuds for triple flange silicone. I have double flanged somewhere, I'll test those in the next few days. I have boxes of the squeezable replacements but always find the triple flange to seal the ears better.The bass is deep but not overblown, voices sound normal and the treble sounds sweet. I tested using music, mp3, FLAC, WAV (rock, classical, some pop, blues, jazz), and a loud full of explosions movie (Mission Impossible Ghost Protocol).Any headphone, earbud or speaker has to do well what it was built for, sound quality first, and these earbuds sound great. Considering they were under £40 makes them an instant 5 star. In I have earbuds costing three times the price and these are right up there with them.What I do not like so much is the cable is a few inches shorter than a normal cable, it's not a big issue. Also, the cable is a sticky type rubber which is great in that no extraneous sound is transmitted to the ears when rubbing or moving against clothes, but can cause the cable to semi-tangle if not correctly stored. This can be a little frustrating but it is entirely livable, no more annoying sounds when walking around.It would be great if RevoNext bought out a non-sticky rubber and slightly longer spare cable and if they offered these earbuds with double or triple flange earbud replacements, then they would have a product that would run and run and run.I'll do a full comparison with 1-More Triple Driver earbuds over the next week or so after I've used the RevoNext for a while longer.Long-term quality is always an issue with cheaper products so I'll do a long-term comparison as well in the future.

The build quality of theses is excellent. Lovely metal build and they fit very comfortably. I use the revonext braided cable with remote, which I think was £8 as the original cable is a bit meh.Out of the box, these sound very clear and airy with slightly flat bass. They are a bit harsh sounding after ten minutes as the BA is in the nozzle. They do have nice shimmer however and are very detailed. The bass is a bit flat at 100 to 200 hz.So I don't have to eq them, I put some foam tips on them and put a tiny piece of tissue in them, which reduces the nozzle size. This reduces the highs and increases the bass a bit, but reduces the detail. It does convert them into bass cannons, however. Which is a bonus for me. It has the added bonus of being reversed in two minutes by removing the tissue.With this mod they are also great for noise isolation.Out of the box, these are more detailed than my KZ zs10 s and those are 5 driver headphones. But it can be a headache, if you are treble sensitive. The sub bass goes deeper han my Kz earphones though and has less decay.

I would've given the earphones an overall 2 stars because of one major disappointment - after 24 hours the left earphone gave up and stopped working - everything else re the earphones is great - so I gave in a gave it another 3rd star. Has to return them and so far can't persuade myself to get another pair - sound alone is fantastic but not sure if I want to take that chance

On first use the IEM's are brilliant. The sound was amazing and comfortable to wear. Unfortunately after only 5 hours use the left speaker stopped working. This seems to be a re-occurring problem with these monitors.Purchase with caution.

Sound is uneven that follows the earbud when switched and they're not actually that comfortable... when you can get them to actually stay in and sealed that is.If it weren't for them issues they seem solidly built and fit comfortably in the ear.

first the sound would randomly cut out in each ear then go back to normal after few hours and now the cable has to be in a specific position to hear music
