Dont let these tiny guys disappoint you by looks. Plug them in and you wont believe your ears. These are that good, It sounds like large over ear headphones. I have owned many earbuds like Sennheiser MX-170, MX-270, MX-580, Tingo TG-38s and for IEMS I have owned TTPOD T1e, JVC HA-FXT90, Sony XB90ex and Yamaha EPH-100 and believe me these tiny earbuds blow all of them out of the water. You can hear the bass rumble like on Sony XB90ex, but with less quantity. The mids are Euphonic and Highs are above average. The best part is the instrument separation...
