Which is better, Sennheiser mx365 or cx2?

if the landlord doesn't like rock and DJ, he doesn't recommend CX2. This earphone is in-ear design, paying more attention to low frequency, and the price is more than 2, while the MX365 has a uniform triple frequency, and the price is more than 1. But I want to recommend SONY E888 to the landlord. This earphone has been in demand for many enthusiasts for almost 1 years now, and it uses a bio-fiber diaphragm, which is definitely for listening to female voices. The frequency range is 8-27, Hz, while the above two deep-sea models are both 2-2-2Hz. Obviously, E888 has more advantages, and the price is around 3. I use it very well, so I strongly recommend it. For MP3 players, I recommend Philips spark2, which uses sigmatel-37 professional chips and Philips' unique flying sound effect. This price is good, more than 2.
