AZLA SednaEarfit Crystal for Bose Earbuds 6Pair - Bose Earbuds Replacement Tips - Ear Tips for Noise Cancelling Headphones - for Bose Quietcomfort Ultra Earbuds, Bose QC Earbuds II

Valen definitivamente la compra. Desde el tacto del material sin duda son mucho mejores que las originales, se ajustan mejor que incluso hay que tirar con fuerza para quitar los audífonos del oído. Mejoran un poco la cancelación de ruido y en cuanto a la calidad de sonido es subjetivo según lo que escuches. Este paquete de todos los tamaños te permite probar para encontrar el fit correcto, llegó en tiempo y forma en perfectas condiciones 👍

音質の違いはわかりませんでしたが、耳から絶対落ちないなと確信を持てるぐらい密着感があります。 ここの評価は人によりけりかと思います。密着感が強くて安心ですが、逆を言えばイヤホンが耳についていると主張してくるわけで、付けてるのを忘れるようなつけ心地を求めている人には合わないです。

These earbuds are a fantastic alternative to the Bose QuietComfort II. The passive noise cancellation is just as effective, thanks to a great seal. Plus, the tips are compatible with the Bose earbuds, which is a huge benefit given how difficult it can be to find replacement Bose tips. I've decided to switch to these permanently. The original Bose tips have a known design flaw—a fragile silicone strip that holds a C-clip in place, which is prone to breaking. These new tips are a much more durable solution.

As advertised, these are high quality silicone. As some have noted on the board, they are not oval, but they mount fine on Bose QCII earbuds. The net effect on the fit is that the tops and bottoms (the "long part" of the oval) is tighter than the sides, but the silicone is thick enough that they fit relatively comfortably. Audio quality and passive noise cancelling are fine. If you have large ear holes, these may not be a good choice for you, as anything larger than medium will cause your earbuds to not fit in the case (at least in the case of my QCII's - maybe on other models it is fine). BTW - I have found that using 3rd party ear tip covers like these https://www.amazon.com/dp/B0CP2BW1S3?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 can improve the ability for the earbuds to stay mounted, and therefore may not need as large of an in-ear size to keep them in place. One other caveat, make sure you have these mounted really well. Because they require some effort to get onto the earbud correctly, a partially mounted one could end up in your ear (almost happened to me). Make sure to give them a good tug before use. These are a little pricey, but the six provided sizes should work for just about anybody (again, though, the large sizes may not work with your charging case). If you have friends with different sized ears than you, you could perhaps trade the extras for a beer or coffee.

El paquete llego en mal estado. La caja estaba apachurrada y toda deformada; para no ser un articulo barato me parece de mala calidad lo que se envío.
