RevoNext QT2S in Ear Monitor, Triple Driver Headphones 2DD+1BA Metal Shell Noise-Isolating Deep Bass HiFi Earbuds with Detachable Cables(Black with mic)

I have been using these for 2 months now. Sound quality is excellent, they still surprise me sometimes with how good they are. The included cable feels a little flimsy, but otherwise these have no real faults.

Fantastic sound at a good place. I've had fairly high-end headphones in the past and these comfortably compete with the best of them.The wire is a little tangly yet stiff enough that it never gets too bad. The around-the-ear cables reduce microphonics (sound from the cables moving around), and makes them very secure on the ears, with the trade off being they take a few seconds longer to insert than the usual type.Included rubber ear buds are low quality (there's a pronounced seam on them from manufacturing and they're a bit plasticky) but do the job and can be easily replaced.Sound is really very good. Wide sound stage and separation (for in-ears), thumping powerful bass and excellent detail. They can sound a little harsh and sibilant with the high-end on some tracks, but you get plenty of detail at the same time.While not perfect, these headphones easily compete with ones costing ten times as much.

The right headphone monitor was defective right out of the box. I tried it on multiple devices to ensure that it wasn't the headphone jack which was at fault. Having to return them for a refund.I had heard that there were quality control issues with these in the past. Was hoping that the issues had been rectified, but that clearly isn't the case. Very disappointing.

Really good sound quality but trust pretty uncomfortable for extended use.

Ottimo il suono e il comfort. Peccato che dopo qualche mese di utilizzo, una delle due cuffie ha iniziato a funzionare solo per qualche minuto per poi diventare muta, o comuniste a suonare con volume e qualità completamente compromessi. Dopo un intervento con un pulisci contatti secco direttamente all'interno della ghiera, ho ripristinato il corretto funzionamento. Consiglio di non usare i tips in silicone, ma quelli (non inclusi) in memory foam che, col vantaggio di isolare maggiormente dall'ambiente esterno, favorisce il corretto funzionamento del dispositivo perché in questo modo è più difficile che lo sporco si depositi all'interno della cuffia.

Actualización al 25-05-2020:Hace 3 meses tramité directamente con Revonext la garantía porque los audífonos comienzan a perder sonido poco a poco al rato de estar utilizándolos. Su atención al cliente fue inmejorable. Sin embargo el reemplazo recibido ya está presentando la misma falla. Me he comunicado de nuevo con Revonext pero esta vez no mantienen la misma comunicación. Es una lástima porque cuando funcionan, los primeros 30 minutos, el sonido es excelente, pero luego van perdiendo potencia y nitidez, llegando incluso a enmudecerse alguno (aleatoriamente) de los audífonos.Opinión original: Excelente sonido. No es muy difícil acostumbrarse a su tamaño pues no estorban, aunque el cable sobre la oreja y que no sea asimétrico, son detalles que aun no me convencen. Versus unos Sennheiser Cx300 que tengo, estos son muchísimo mas amplios de calidad y nitidez de sonido.

Dès les premières écoutes on profite d'une qualité de son incroyable, digne de modèles hauts de gamme. Ça c'est du son, du bon ! Basse percutantes mais précises, médium bien présents et aigus détaillés. Bonne séparation des instruments et spatialisation. Bons, très très bon même !!! Seul petit reproche : les oreillettes livrées sont a peine assez grandes, même la plus grande taille. Profitez-en avec une source audio de qualité, ils les méritent ! Wahouh.... j'y retourne !!!

tienen un buen sonido,de eso no hay duda .el problema es que con poco tiempo de uso ,el canal derecho comienza a fallar aleatoriamente,unas veces se queda sin frecuencias bajas y otras no emite ningún sonido y de repente vuelve a funcionar bien,fue comprobado con varios cables y el problema persistía.después de leer varios comentarios en amazon.com veo que es un problema habitual,devueltos .una pena por que el sonido era genial
