Ingress protection ratings refer to the level of protection given by an enclosure, against solids and liquids. The letters 'IP' are followed by two values The first value refers to protection against solids say dust, followed by the one that refers to resistance against liquids (water).
Having a value of IPX4, the Bose SoundSport Free's rating is read as, the first number of X denotes that no data available to specify a protection rating, and the second number of 4 means that they can withstand low pressure spray similar to that of a shower head when tilted at 180° for 10 minutes. In comparison to the Bose SoundSport Free, Sony LinkBuds S have a rating of IPX4 meaning that
we are not yet certain of their rating with solids (dust)
and that of liquids is that,
they both have the same rating against liquids

which implies that they have a smaller driver unit than that of Bose SoundSport Free by 5mm
, a common assumption that driver units of a bigger size automatically produce better sound quality.
However, large drivers find it difficult to produce high frequencies so it's true that, larger drivers can generate louder sound, but this does not indicate that they deliver better quality sound. The Bose SoundSport Free's lowest frequency is at 20Hz, low-frequency response measures if and how well an audio device produces low frequencies that can be heard, and if it alters the signal while at it.
Sony LinkBuds S's lowest frequency is at 20Hz, this means that
both devices produce equal bass
The Bose SoundSport Free's highest frequency is at 20,000Hz, high-frequency response shows how well a particular audio device generates high human frequencies and if it changes to the signal on its way through. Sony LinkBuds S's highest frequency is at 40,000Hz, this means that
Sony LinkBuds S can produce a clearer and crispier treble than the Bose SoundSport Free
