Neoteck 3.5mm Headphone Amp with Bass Boost

Neoteck’s compact 3.5mm headphone amp delivers cleaner, louder hi‑fi sound with an optional bass boost for headphones from 16 to 600 Ω.

Small enough to fit in a pocket yet built with an aluminum matte finish, this portable headphone amplifier raises volume headroom and refines audio detail for phones, laptops, MP3 players, tablets and gaming controllers. It uses a 3.5mm input/output chain, a high signal‑to‑noise ratio and ultra‑low distortion to preserve clarity when driving both sensitive in‑ear monitors and demanding over‑ears. A one‑touch bass switch adds low‑end presence when you want more impact, while a rechargeable battery keeps the unit running for extended listening sessions.

How does this amplifier improve everyday listening?

The Neoteck amp increases available power and reduces background noise, so tracks sound more open and instruments sit clearer in the mix. It raises perceived loudness without pushing your source device to distortion, which is useful for low‑gain phones or older MP3 players.

• High SNR (>100 dB) for quieter backgrounds and better detail
• THD+N 0.0005% to preserve sonic accuracy at higher volumes
• Compatible with 16–600 Ω headphones for a wide range of cans
• Simple 3.5mm pass‑through hookups for plug‑and‑play use

When should I use the bass boost switch?

Flip the bass switch when you want fuller low frequencies for movies, electronic music or gaming. It enhances low‑end warmth without muddying mids, giving percussion and basslines more presence for a more immersive experience.

• Engage for bass‑heavy tracks or cinematic soundscapes
• Leave off for neutral, reference listening and vocal clarity
• Quick hardware toggle—no app or software required

Will it work with my device and headphones?

Yes. The unit accepts a 3.5mm input and provides a 3.5mm headphone output, making it compatible with most smartphones, tablets, laptops, MP3 players and controllers that expose an analog jack. Its output stage supports a wide impedance range so both sensitive and high‑impedance headphones can be driven more effectively.

• Works with phones, iPad, Mac, PC, PS4/PS5 controllers and portable players
• Supports headphones from 16 Ω to 600 Ω
• Analog 3.5mm input/output for universal connectivity

How long does the battery last and how do I charge it?

The built‑in rechargeable battery provides more than eight hours of continuous playback on a single charge, suitable for commutes, flights and long listening sessions. For best performance, avoid using the amplifier while charging to prevent current interference and ensure safety.

• 8+ hours typical playback per full charge
• Rechargeable battery with standard USB charging (cable included)
• Recommended: charge between uses, avoid simultaneous play‑while‑charging

Who is this for? Audiophiles and casual listeners who want an affordable, portable step up from a device’s built‑in headphone driver will appreciate the Neoteck amp. It’s ideal for commuters, gamers, students and anyone who uses multiple source devices and desires clearer dynamics, louder volume without clipping, and an optional bass enhancement in a lightweight, durable package.
