The picks, ranked
Ordered by rating, review volume, and how well each one holds up over time — top pick first.
The JBL Charge 4 is recommended for its performance among budget speakers.
✓ Pros
- ✓ It's a good alternative to other portable Bluetooth speakers like the Koss KPH30i and JBL Charge 3.
- ✓ One reviewer has high-end audio experience with it
✗ Cons
- ✗ Newer to our list — less long-term data
Optical out, bass boost switch, 32-150 Ohm output power. The entry-level DAC/amp that transforms your computer's terrible audio into something audiophiles actually respect.
✓ Pros
- ✓ Massive sound upgrade from PC audio
- ✓ Works with 32-150 Ohm headphones
- ✓ Optical output
✗ Cons
- ✗ No balanced output
- ✗ USB-B (older connector)
A $20 IEM that makes audiophiles visibly uncomfortable. Single dynamic driver tuned to Moondrop's VDSF target curve — which is a fancy way of saying they sound exactly right. r/headphones recommends these to everyone who says they can't afford good audio.
✓ Pros
- ✓ Audiophile-tuned for $20
- ✓ Detachable cable
- ✓ Excellent imaging for price
✗ Cons
- ✗ Wired only (IEM style)
- ✗ No mic on base model
The Chu II's closest competition — and r/headphones loves pitting them against each other. Wider soundstage, slightly different tuning, same absolutely unacceptable-for-the-price performance. Buy both. Seriously. They're $20 each.
✓ Pros
- ✓ Wide soundstage for the price
- ✓ Harman-adjacent tuning
- ✓ Comfortable long-wear fit
✗ Cons
- ✗ Wired only
- ✗ Build feels plasticky
Cardioid condenser USB mic with an adjustable desk arm included. Records podcasts, music, gaming sessions, and voice-overs in rich quality — and the arm alone would cost $20 on its own.
✓ Pros
- ✓ Arm stand included
- ✓ Rich condenser sound under $50
- ✓ Plug-and-play
✗ Cons
- ✗ Arm isn't super sturdy
- ✗ No gain knob
