Source: GalaxusWe already found it difficult to make a clear judgement on the Sony LinkBuds Open. It is even more difficult with the Sony LinkBuds Fit. While the LinkBuds Open are far removed from the in-house competition due to their open design and therefore don't necessarily have to be measured against them in terms of price, the LinkBuds Fit are a different story...
Also new in Stiftung Warentest's constantly updated headphone database: 16 current Bluetooth headphones - including in-ears, open-ears and headband models. One in-ear reduces ambient noise perfectly, another fails in this test point. The devices also perform very differently in terms of wearing comfort: many fit well or very well, others fall out of the ear easily...
I would describe the LinkBuds from Sony as standard fare. The headphones work as they should and deliver a decent sound. However, in the now very saturated true wireless market, you can find better products for the same price - both in terms of sound, app and operation.
The new Sony LinkBuds cut a fine figure in both versions. In addition to the very long battery life, this is due to the good sound quality during phone calls and the great app. Nevertheless, there are problems here and there: Although the Open are pleasantly open, wearing comfort and sound are not always ideal. The Fit scores highly in terms of sound, but the noise cancellation is rather weak.
