- [Sennheiser CX300 II](/headphone-measurements/iems/sennheiser/sennheiser-cx300-ii.md): Resolution is missing and tuning is quite wrong
- [Sennheiser CX880i](/headphone-measurements/iems/sennheiser/sennheiser-cx880i.md): Good 'open' sound.
- [Sennheiser CX890i](/headphone-measurements/iems/sennheiser/sennheiser-cx890i.md)
- [Sennheiser Momentum M2 IEi](/headphone-measurements/iems/sennheiser/sennheiser-momentum-m2-iei.md): Ok, but not great. Cheap earbuds are better in most ways.
