Build Aspect

Infinity Swing 350 from JBL is a True Wireless earphone offering ₹ 3000 in India. This pair of TWS earphones are well constructed and feel relatively robust. They are quite slim and have a matte and gloss finish combination which gives them a decent look. In-ear comfort levels are really good and they are rather sturdy and won’t fall off easily. Furthermore these have some tolerance against foreign elements since they are IPX4 rated.

Performance Aspect

JBL Infinity Swing 350 Bluetooth Earphones have a good sound signature with a tuning that will please most if not all. Essentially they have decent bass, natural mid range and extended treble. Although treble can be a bit too bright on some tracks. Nonetheless Swing 350 delivers an enjoyable and non fatiguing sound for hours at a stretch. So it would suffice to say to wrap up by saying that the Swing 350 are one of the best wireless earphones under 3000 Rupees in India.
