It bridges the gap between ultra-premium players and more mainstream options, offering detailed sound and support for most lossless formats, plus the flexibility of Android music streaming apps. The tiny player features Bluetooth 5.3, Hi-Res audio, up to 250mW of power, the option to use 3.5mm or 4.4mm wired headphones, and wide compatibility with all of the most popular file formats, including FLAC, MP3 and OGG. Quirks aside, this is a cute little audio gadget that’s ideal for taking your music streaming offline, with storage for over 1,000 tracks and support for both wired and wireless earphones. A hi-res audio player, music streamer and DAC, the Activo P1 natively supports most audio file formats, from compressed MP3 to lossless, 32-bit FLAC. For audiophiles, dedicated players pack superior digital-to-analogue converters (DACs), higher power outputs and support for lossless audio formats to deliver truly high-resolution sound that your phone simply can’t match.

What’s the difference between balanced and unbalanced output on hi-res players?

Expandable storage also gives you much more flexibility in what you carry with you, and lets you listen offline without relying on streaming services. Yes, you can listen to a hi-res audio player wirelessly, but it’s worth remembering that Bluetooth usually compresses audio. DSD is known for capturing exceptional detail with a smooth, natural sound that many audiophiles prefer. This is 64 times that of 44.1 kHz, aka CD audio sampling rate, but with 1-bit samples instead of 16-bit. Unlike PCM, which uses multi-bit recordings (like 16-bit for CD quality), DSD employs a 1-bit Sigma Delta Modulated (SDM) system. If you’re using budget headphones or mostly stream compressed music from services like Spotify, you may not hear a dramatic difference.

So while you should really be giving it all of the 24bit/192kHz FLAC files, this particular Astell & Kern will readily tolerate and deliver 320kbps Spotify streams better than most. Also, while the SR35 deserves the best standard of content, it’s less fussy than many rival players. Sound quality is superb for the price, detailed, and well-balanced, with an impressively wide soundstage. With over 12 hours of battery life, it outperforms most entry-level players. Despite its price, it packs twin Cirrus Logic CS43198 DACs, supports 32-bit/384kHz and DSD256, and includes high-performance op-amps in a fully balanced layout. Activo launched the Q1 in-ears to go with it at the end of 2024 and our full Activo Q1 review is glowing about them – and the sound profile combines superbly with the player.

What are lossless and lossy audio files?

For serious music fans, Bluetooth audio, while better than it used to be, still can’t deliver full hi-res quality without a wired connection. Even so, Bluetooth always involves some compression, which is why many audiophiles still feel that hi-res music sounds best through a wired setup. The difference between listening to hi-res audio with wired vs wireless headphones used to be huge, but that gap is slowly closing. There are a few different ways to get hi-res music files, and the best option depends on whether you prefer downloading or streaming. By comparison, CD-quality audio is much higher resolution at 1,411 kbps, while the best MP3 files top out at 320 kbps. Not everyone will notice or care about the uplift in sound quality, but for the people who do, an MP3 player can make a huge difference to how they listen.
