Hi guys,
I don't know if I'm doing something wrong or not.
I've had the Jaybird BlueBuds X in-ear Bluetooth headphones for 3.5 years. I wanted something a bit different and as the battery life was worse than half now I decided to go for the RHA T20s. Nice build.
I've had them for 2 days. Upon listening to the reference filters and changing the tips to the most suitable, I thought they sounded tinny with no EQ. Bass filter made it slightly better but sounded dull and either the same or worse sound as the Jaybird's. Put it onto the Treble filter and really made it more lively which I loved and just EQed a bit as was a bit sharp sounding.
With my typical music - Hard Rock and Metal, it doesn't really seem like a step up in quality over my Jaybirds and given I'm using it for commuting, I'm very tempted to return.
To clarify: Using a Huawei P20 Pro with Spotify Premium and Tidal Hi-Fi, no external DAC.
I am a metal listener too. T20i was my first expensive IEM (if you take IEM's $100 + starts as as entry level audiophile). I listened to it with a midrange phone of $200. Before, I was listening to my friend's $150 Bose QC Sport BT for a month. And initially I didn't feel any difference. By Dual DD, T20i is suppose to sound a wide difference. After a week (around 20-30hours burnout), I started to like the sound. I realised T20i is more sharper than the QC sport. The base and drums sounds tingly with sharp impact, but not bloating punches like from cheap loud subwoofers. So actually I fell in love and kept them for a year.
Actually, first I was going for T10, but reading reviews and users impressions on this thread and the T10 thread, saying T10 is punchy bassy, but T20 has concentrated on more sharp clarity.
The reference filters aren't much deal, they just make a slight difference. The basic sound signature is already tuned and it cant be altered with filters. That's just a RHA's marketing tool.
Bose, Jaybird, JBL, Beats and such similar companies concentrate on the common consumer market. They put things which most people pays attention firstly - nice bassy bits, warmness and the loudness. Most people won't suddenly like the "neutral clarity" from a $1000+ audiophile IEM.
I tried upgrading into a DAP and bought Sony ZX-300. From "direct sound" it didn't sound much differ than my phone, but after setting EQ, and other software improvements, it become more wide and bright. So I take this as ZX-300's own signature. T20 doesn't bring much improvement from an DAC or DAP unless your phone's DAC is really poor. Usually most $150 + phones already has good DAC for T20.
So give yourself at least 2 weeks before you decide to return or sale. And finally it depends on your tatse. For me I would still prefer sharp base if I am playing Lamb of God. Whereas others might prefer punchy bass from the base amd drums. If it is Dragonforce or Blind Guardian, then sharp separation is a must. So T20 is really good for $200 budget.
