This is the second time I’ve bought this brand, and I have had a good experience with using them. My first pair of Sennheiser CX 300 lasted three years before one earbud stopped working properly - much longer than all the previous brands I’ve bought.

The earbuds sit nicely in my ears, the control on the cord works well & the microphone works well when on a call or in an online meeting. I use them daily for listening to music, audiobooks and podcasts on my phone, and am happy with the sound quality.

I had never used headphones, decided I wanted some, couldn't decide on type so I bought two Sennheiser products: This one (AU$59.00) plus their Over Ear Headphones HD 300 (AU$83.75).
About this product: Sound quality is fine, it's just quite fiddly to position them correctly in your ears, a millimeter to the left or right or further into your ears makes all the difference! The three included different-size ear adapters are an excellent feature that I did not find elsewhere in my research.
That said: I find my new Sennheiser Over Ear Headphones hugely more comfortable!

Premetto di essere malato di audiofilia ho acquistato questi auricolari incuriosito dalle buone recensioni ho avuto diversi altri prodotti anche di costo superiore senza andare a menzionare marchi e modelli mi sento di dire che una qualità di riproduzione musicale del genere non credevo fosse possibile in questa fascia di prezzo con un estensione della frequenza impressionante soprattutto in basso pero' hanno un difetto creano dipendenza difficile riuscire a levare gli auricolari dalle orecchie ascoltare musica a questo livello qualitativo è goduria allo stato puro scherzi a parte le CX 300 S sono fantastiche per ascoltare musica 5 stelle sono poche

These headphones are very well made a nice thicker than normal cable so I would like to think it will last a long time.
Great sound with a nice punchy base and a very clear mid-range.
I've been buying Sennheisers since my mid-teens and they've always performed.
Fantastic pair of headphones 5 all day long .

Sennheiser in-ear är helt klart min favorit, jag provade många olika märken innan jag hittde rätt : )

Efter ett dagligt använda in-ear lurar under ca 10 år, de sista 6 åren Sennheiser har detta märke aldrigt krånglat etter gjort mig besviken, bra suport från Sennheiser med.

Rekomenderas således mycket starkt !!

Auriculares de muy alta calidad de audio para su gama de precio. Cordón diseñado para minimizar rizos y nudos. Buena sujeción al oído, si llegar a molestar. Muy recomendable.
