Muy buena calidad de sonido y seguramente muy fiables,la unica pega es que sientan un poco duros e incomodos al llevarlos puestos.

Overall, I like this IEM a lot. I love the sound profile, though the comfort may be left desired. The IEM is smooth, lean, warm-tilted, and balanced at the same time. It's a great addition to your collection if you'd like a warm, fun, and a bit colored sound signature.

Pros: - VERY wide soundstage, - Sound profile that doesn't offend most people yet keeping it balanced, - Decent detail and separation, decent, clear, balanced sound, won't offend, - beautifully balanced sound, - excellent sound separation, - great imaging, - neutral tonality...

Cons: - Comfort is not for everyone, - Soundstage doesn't have much depth, - High rolled off pretty early, - Tip rolling is a MUST, - Cable is too long for daily, uncomfortable, too big (both nozzle size and body), for me, due to the above two reasons, unusable, rather harsh highs, quite cheap sounding,,...

The audio quality is great, but the reinforced section of the cable that you bend around your ear broke after 6 months of use and the left earbud no longer stays in place. A bit disappointing considering the price.

Pros: Good Bass, Great Sound

Cons: Falls Off/Out Of Ear, Flimsy Construction, Poor Value

By far the best budget in ear monitors I’ve used! Sounds clean and balanced! My experience with other brands within the same price range has been mediocre at best! These are definitely worth it!

I play keyboards and I needed in-ear monitor, whether it's wireless or wired. Since I don't move on stage too much, I decided to use the wired option and needed good in-ear buds. I found them! Fit well -- can be adjusted to fit perfectly due to their design. Hi-fi sound too!

As a bass player, Ath E40 gives an incredible sound,easy-to-use and really affordable for that level of quality. You guys should try this one!

I am a drummer in a band and wear these at least 3 time a week. I have never had any issues with them at all. Good bass without losing the vocals from the mix. I use the Comply T-500 tips.

Pros: Comfortable, Durable, Good Bass, Good Value, Great Sound

Really great bass response and highs for in ear monitors, for the price you can’t beat these.

It's definitely a decent earphone with a reasonable price. It works very good for pop and rock music. I will reccommand this product to my friend.

These in-ear headphones were my first from Audio-Technica's lineup. The sound quality on these headphones are superb and can definitely handle bass with quality and clarity. Out of the box these headphones do not provide a passive bass boost but that should not deter any user from purchasing these...

Pros: Compact, Durable, Easy To Use, Good Audio, Lightweight, Versatile

Cons: Bulky/Heavy
